military threats to human rights concerns. Some were longstanding, others of newer vintage.
During the Cold War, the prospect of nuclear annihilation led to historic treaties and a framework that kept the world from blowing itself up. At this meeting, for the first time, cyberweapons — with their own huge potential to wreak havoc — were at the center of the agenda.
But Mr. Putin’s comments to the media suggested the two leaders did not find much common ground.
In addition to his denials that Russia had played a destabilizing role in cyberspace, he also took a hard line on human rights in Russia.
He said Mr. Biden had raised the issue, but struck the same defiant tone on the matter in his news conference as he has in the past. The United States, Mr. Putin said, supports opposition groups in Russia to weaken the country, since it sees Russia as an adversary.
“If Russia is the enemy, then what organizations will America support in Russia?” Mr. Putin asked. “I think that it’s not those who strengthen the Russian Federation, but those that contain it — which is the publicly announced goal of the United States.”
President Biden said on Wednesday that “I did what I came to do” in his first summit meeting with President Vladimir V. Putin of Russia.
Speaking after the summit in Geneva, Mr. Biden said the two leaders had identified areas of mutual interest and cooperation. But he said he had also voiced American objections to Russia’s behavior on human rights, and warned that there would be consequences to cyberattacks on the United States.
Any American president representing the country’s democratic values, Mr. Biden said, would be obliged to raise issues of human rights and freedoms. And so he said had discussed with Mr. Putin his concerns over the imprisonment of the Russian opposition leader Aleksei A. Navalny and warned there would be “devastating” consequences if Mr. Navalny were to die in prison.
Mr. Biden also brought up the detentions of two American citizens in Russia, Paul Whelan and Trevor Reed, he said.
On the issue of cybersecurity, Mr. Biden said he had argued that certain parts of the infrastructure need to be off limits to cyberattacks. He said he had provided Mr. Putin with a list of critical areas, like energy, that must be spared. Mr. Biden also said the two leaders had agreed to enlist experts in both countries to discuss what should remain off limits and to follow up on specific cases.
“We need to have some basic rules of the road,” Mr. Biden told reporters after the summit.
And if Russia continues to violate what he called the basic norms of responsible behavior, he said, “We will respond.”
Mr. Biden made clear that, during his discussions with Mr. Putin, there were no threats, no talk of military intervention and no mention of what specific retaliation the United States would take in such cases. But Mr. Biden said that the United States was fully capable of responding with its own cyberattacks —“and he knows it.”
Mr. Biden said “there’s much more work to do,” but declared over the course of his weeklong European trip, he had shown that “the United States is back.”
He also said Russia stood to lose internationally if it continued to meddle in elections. “It diminishes the standing of a nation,”Mr. Biden said.
President Vladimir V. Putin on Wednesday repeated well-worn denials of Russian mischief and tropes about American failings, as he spoke to the press after his first summit with President Biden.
But between those familiar lines, he left the door open to deeper engagement with Washington than the Kremlin had been willing to entertain in recent years. On issues like cybersecurity, nuclear weapons, diplomatic spats and even prisoner exchanges, Mr. Putin said he was ready for talks with the United States, and he voiced unusual optimism about the possibility of achieving results.
“We must agree on rules of behavior in all the spheres that we mentioned today: That’s strategic stability, that’s cybersecurity, that’s resolving questions connected to regional conflicts,” Mr. Putin said at a nearly hourlong news conference after the summit. “I think that we can find agreement on all this — at least I got that sense given the results of our meeting with President Biden.”
Mr. Putin’s focus on “rules of behavior” sounded a lot like the “guardrails” that American officials have said they hope to agree on with Russia in order to stabilize the relationship. “Strategic stability” is the term both sides use to refer to nuclear weapons and related issues.
To be sure, there is no guarantee that the United States and Russia will make progress on those fundamental issues, and American officials fear Russian offers of talks could be efforts to tie key questions up in committees rather than set clear red lines. But in recent years, substantive dialogue between the two countries has been rare, making Wednesday’s promises of new consultations significant.
But Mr. Putin fell back on familiar Kremlin talking points to bat away criticisms, pointing to supposed human rights violations in the United States and denying Russian complicity in cyberattacks. He also refused to budge in response to questions over his repression of dissent inside Russia and the imprisonment of the opposition leader Aleksei A. Navalny. As he has said in the past, he repeated that the Kremlin does not see domestic politics as up for negotiation or discussion.
“If you ignore the tiresome whataboutism, there were some real outcomes,” said Samuel Charap, a senior political scientist at the RAND Corporation in Arlington, Va. “Russia is not in the habit of confessing its sins and seeking forgiveness. Particularly under Putin.”
The main outcomes to Mr. Charap were the agreement on U.S.-Russian dialogue on strategic stability and cybersecurity, as well as the agreement for American and Russian ambassadors to return to their posts in Moscow and Washington. Mr. Putin also said there was “potential for compromise” on the issue of several Americans imprisoned in Russia and Russians imprisoned in the United States.
To tout his renewed willingness to talk — while acknowledging the uncertainty ahead — Mr. Putin quoted from Russian literature.
“Leo Tolstoy once said: ‘There is no happiness in life — there are only glimmers of it,’” Mr. Putin said. “I think that in this situation, there can’t be any kind of family trust. But I think we’ve seen some glimmers.”
After President Biden met his Russian counterpart on Wednesday, the two men did not face the news media at a joint news conference.
President Vladimir V. Putin of Russia spoke first, followed by Mr. Biden, in separate news conferences, a move intended by the White House to deny the Russian leader an international platform like the one he received during a 2018 summit in Helsinki with President Donald J. Trump.
“We expect this meeting to be candid and straightforward, and a solo press conference is the appropriate format to clearly communicate with the free press the topics that were raised in the meeting,” a U.S. official said in a statement sent to reporters this weekend, “both in terms of areas where we may agree and in areas where we have significant concerns.”
Top aides to Mr. Biden said that during negotiations over the meetings the Russian government was eager to have Mr. Putin join Mr. Biden in a news conference. But Biden administration officials said that they were mindful of how Mr. Putin seemed to get the better of Mr. Trump in Helsinki.
At that news conference, Mr. Trump publicly accepted Mr. Putin’s assurances that his government did not interfere with the 2016 election, taking the Russian president’s word rather than the assessments of his own intelligence officials.
The spectacle in 2018 drew sharp condemnations from across the political spectrum for providing an opportunity for Mr. Putin to spread falsehoods. Senator John McCain at the time called it “one of the most disgraceful performances by an American president in memory.”
Piggybacking on the attention to Russia with the Biden-Putin meeting on Wednesday, the European Union issued a long and pessimistic report on the state of relations between Brussels and Moscow.
“There is not much hope for better relations between the European Union and Russia anytime soon,” said Josep Borrell Fontelles, the E.U.’s foreign policy chief, introducing the report. It was prepared in advance of a summit meeting of European leaders next week at which the bloc’s future policy toward Russia will be on the agenda.
That discussion has been delayed several times by other pressing issues, including the pandemic.
“Under present circumstances, a renewed partnership between the E.U. and Russia, allowing for closer cooperation, seems a distant prospect,” Mr. Borrell said in a statement, introducing the 14-page report prepared by the European Commission.
The report urges the 27-member bloc to simultaneously “push back” against Russian misbehavior and violations of international law; “constrain” Russia’s efforts to destabilize Europe and undermine its interests, especially in the Western Balkans and neighboring post-Soviet states; and “engage” with Russia on common issues like health and climate, “based on a strong common understanding of Russia’s aims and an approach of principled pragmatism.”
The ambition, Mr. Borrell said, is to move gradually “into a more predictable and stable relationship,” a similar goal to that expressed by the Biden administration.
Mr. Borrell had an embarrassing visit to Moscow in February as he began to prepare the report. He stood by without reacting in a joint news conference as his Russian counterpart, Foreign Minister Sergey Lavrov, called the European Union an “unreliable partner.”
As they were meeting, Moscow announced that diplomats from Germany, Poland and Sweden had been expelled for purportedly participating in “illegal protests” to support the jailed opposition politician Aleksei A. Navalny, a fact Mr. Borrell discovered only later through social media.
He defended the trip, telling the European Parliament that he “wanted to test whether the Russian authorities are interested in a serious attempt to reverse the deterioration of our relations and seize the opportunity to have a more constructive dialogue. The answer has been clear: No, they are not.”
Relations have worsened since then with overt Russian support for a crackdown against democracy and protests in Belarus.
Even before the summit between the United States and Russia got underway on Wednesday, Ukrainian officials played down the prospect for a breakthrough on one of the thornier issues on the agenda: ending the war in eastern Ukraine, the only active conflict in Europe today.
Ukraine said it would not accept any arrangements made in Geneva between President Biden and President Vladimir V. Putin on the war, which has been simmering for seven years between Russian-backed separatists and the Ukrainian Army, officials said.
Before the summit’s start, Dmitri S. Peskov, the Kremlin’s spokesman, said that Ukraine’s entry into NATO would represent a “red line” for Russia that Mr. Putin was prepared to make plain on Wednesday. Mr. Biden said this week that Ukraine could join NATO if “they meet the criteria.”
The Ukrainian government has in recent years dug in its heels on a policy of rejecting any negotiation without a seat at the table after worry that Washington and Moscow would cut a deal in back-room talks. The approach has remained in place with the Biden administration.
“It is not possible to decide for Ukraine,” President Volodymyr Zelensky said on Monday. “So there will be no concrete result” in negotiations in Geneva, he said.
Ukraine’s foreign minister drove the point home again on Tuesday.
“We have made it very clear to our partners that no agreement on Ukraine reached without Ukraine will be recognized by us,” Dmytro Kuleba, the foreign minister, told journalists. Ukraine, he said, “will not accept any scenarios where they will try to force us to do something.”
Ukraine will have a chance for talks with the United States. Mr. Biden has invited Mr. Zelensky to a meeting in the White House in July, when a recent Russian troop buildup along the Ukrainian border is sure to be on the agenda.
Russia massed more than 100,000 troops along the Ukrainian border this spring. Despite an announcement in Moscow of a drawdown, both Ukrainian and Western governments say that only a few thousand soldiers have departed, leaving a lingering risk of a military escalation over the summer.

If President Biden wanted an example of a summit that did not go according to plan, he needed only to look back to 2018.
That year, President Donald J. Trump flew to Helsinki to meet President Vladimir V. Putin of Russia, the first face-to-face meeting between the two and a highly anticipated moment given the then-ongoing investigations of Russian interference and cooperation with Mr. Trump’s 2016 presidential campaign.
It might have been a chance for Mr. Trump to push back against those accusations by offering a forceful denunciation of Russia’s actions in private, and again during a joint news conference by the two men.
Instead, standing on the stage by Mr. Putin’s side, Mr. Trump dismissed the conclusions by U.S. intelligence agencies about Russian meddling and said, in essence, that he believed Mr. Putin more than he did the C.I.A. and other key advisers
“They said they think it’s Russia,” Mr. Trump said. “I have President Putin; he just said it’s not Russia.” He added that he didn’t see any reason Russia would have been responsible for hacks during the 2016 election. “President Putin was extremely strong and powerful in his denial today.”
It was the kind of jaw-dropping assertion that U.S. administrations usually strive to avoid in the middle of highly scripted presidential summits. Critics lashed out at Mr. Trump for undermining his own government and for giving aid and comfort to an adversary. Even Republican allies of the president issued harsh denunciations.
“It is the most serious mistake of his presidency and must be corrected — immediately,” said Newt Gingrich, the former Republican House speaker and a staunch supporter of Mr. Trump.
There was nothing about the one day Helsinki summit that was normal. Mr. Putin and Mr. Trump were so chummy that the Russian president gave Mr. Trump a soccer ball to take home as a gift. Mr. Trump thanked him and bounced the ball to Melania Trump, the first lady, in the front row, saying he would take it home to give it to his son, Barron.
(Sarah Sanders, the White House press secretary at the time, later issued a statement saying that the ball — like all gifts — had been examined to make sure it had not been bugged with listening devices.)
In a statement issued as Mr. Biden headed to Europe last week, Mr. Trump once again called his meeting with Mr. Putin “great and very productive” and he defended supporting the Russian president over his intelligence aides.
“As to who do I trust, they asked, Russia or our ‘Intelligence’ from the Obama era,” he said in a statement. “The answer, after all that has been found out and written, should be obvious. Our government has rarely had such lowlifes as these working for it.”
The former president also took a cheap shot at his successor in the statement, warning him not to “fall asleep during the meeting.”
One thing was certain — Mr. Biden did not follow through on Mr. Trump’s request that when Mr. Biden met with Mr. Putin “please give him my warmest regards!”
In the United States, fireworks lit up the night sky in New York City on Tuesday, a celebration meant to demonstrate the end of coronavirus restrictions. California, the most populous state, has fully opened its economy. And President Biden said there would be a gathering at the White House on July 4, marking what America hopes will be freedom from the pandemic.
Yet this week the country’s death toll passed 600,000 — a staggering loss of life.
In Russia, officials frequently say that the country has handled the coronavirus crisis better than the West and that there have been no large-scale lockdowns since last summer.
But in the week that President Vladimir V. Putin met with Mr. Biden for a one-day summit, Russia has been gripped by a vicious new wave of Covid-19. Hours before the start of the summit on Wednesday, the city of Moscow announced that it would be mandating coronavirus vaccinations for workers in service and other industries.
“We simply must do all we can to carry out mass vaccination in the shortest possible time period and stop this terrible disease,” Sergey S. Sobyanin, the mayor of Moscow, said in a blog post. “We must stop the dying of thousands of people.”
It was a reversal from prior comments from Mr. Putin, who said on May 26 that “mandatory vaccination would be impractical and should not be done.”
Mr. Putin said on Saturday that 18 million people had been inoculated in the country — less than 13 percent of the population, even though Russia’s Sputnik V shots have been widely available for months.
The country’s official death toll is nearly 125,000, according to Our World in Data, and experts have said that such figures probably vastly underestimate the true tally.
While the robust United States vaccination campaign has sped the nation’s recovery, the virus has repeatedly confounded expectations. The inoculation campaign has also slowed in recent weeks.
Unlike many of the issues raised at Wednesday’s summit, and despite the scientific achievement that safe and effective vaccines represent, the virus follows its own logic — mutating and evolving — and continues to pose new and unexpected challenges for both leaders and the world at large.
The conflict in Syria — which has now raged for 10 years and counting — was on the meeting agenda for President Biden and President Vladimir V. Putin of Russia as they met on Wednesday.
Since the start of the war, Russia has supported President Bashar al-Assad and his forces, and in 2015 it launched a military intervention with ground forces in the country to prop up the then-flailing government. In the years since, government forces have regained control of much of the country, with the support of Russia and Iran, as Mr. al-Assad’s forced tamped down dissent and carried out brutal attacks against Syrian civilians.
The United States also became deeply involved in the conflict, backing Kurdish forces in the country’s north and conducting airstrikes in the fight against the Islamic State. It has maintained a limited military presence there. Both the United States and Russian forces have found themselves on opposite sides of the multifaceted conflict on numerous occasions.
After years of failed attempts at peace in Syria as the humanitarian toll has continued to mount, Lina Khatib, the director of the Middle East and North Africa Program at Chatham House, a British think tank, said the moment could be ripe for the two major powers to chart a path forward.
She said that “despite taking opposing sides in the Syrian conflict, there is potential for a US-Russian compromise,” and that the summit could be the best place to begin that process.
“The Biden administration must not waste the opportunity that the U.S.-Russian summit presents on Syria,” Ms. Khatib wrote in a recent piece before the meeting in Geneva. “While the focus of various U.S. government departments working on Syria is on the delivery of cross-border aid, fighting the Islamic State and planning an eventual exit for U.S. troops, all these problems are products of the ongoing conflict, and solving them requires a comprehensive strategy to end it.”
American and Russian reporters engaged in a shoving match on Wednesday outside the villa where President Biden and President Vladimir V. Putin of Russia were meeting, stranding much of the press outside when the two leaders began talking.
The chaotic scrum erupted moments after Mr. Biden and Mr. Putin shook hands and waved to reporters before closed-door meetings with a handful of aides.
President Guy Parmelin of Switzerland had just welcomed the leaders “in accordance with its tradition of good offices” to “promote dialogue and mutual understanding.”
But shortly after the two leaders entered the villa, reporters from both countries rushed the side door, where they were stopped by Russian and American security and government officials from both countries. There was screaming and pushing as both sides tried to surge in, with officials yelling for order.
White House officials succeeded in getting nine members of their 13-member press pool into the library where Mr. Biden and Mr. Putin were seated against a backdrop of floor-to-ceiling books, along with each of their top diplomats and translators. The two leaders had already begun to make very brief remarks before reporters were able to get in the room.
Inside, more scuffling erupted — apparently amusing to the two leaders — as Russian officials told photographers that they could not take pictures and one American reporter was shoved to the ground. The two leaders waited, at moments smiling uncomfortably, for several minutes before reporters were pushed back out of the room as the summit meeting began.
“It’s always better to meet face to face,” Mr. Biden said to Mr. Putin as the commotion continued.
Chaotic scenes are not uncommon when reporters from multiple countries angle for the best spot to view a world leader, often in cramped spaces and with government security and handlers pushing them to leave quickly.
But even by those standards the scene outside the villa in this usually bucolic venue was particularly disruptive. Russian journalists quickly accused the Americans for trying to get more people into the room than had been agreed to, but it appeared that the Russians had many more people than the 15 for each side that had been negotiated in advance.
“The Americans didn’t go through their door, caused a stampede,” one Russian reporter posted on Telegram.
In fact, reporters from both countries had been told to try to go through a single door, and officials for both countries at times were stopping all of the reporters from entering, telling them to move back and blocking the door.
When American officials tried to get White House reporters inside, the Russian security blocked several of them.
Wednesday’s Geneva summit got off to an auspicious start: President Vladimir V. Putin of Russia landed on time.
His plane landed at about 12:30 p.m., an hour before he was set to meet President Biden, who had arrived in Geneva the previous evening. Mr. Putin is known for making world leaders wait — sometimes hours — for his arrival, one way to telegraph confidence and leave an adversary on edge.
But this time Mr. Putin did not resort to scheduling brinkmanship.
The summit’s start was laced with delicate choreography: Mr. Putin arrived first, straight from the airport, and was greeted on the red carpet in front of a lakeside villa by President Guy Parmelin of Switzerland. About 15 minutes later, Mr. Biden arrived in his motorcade, shook hands with Mr. Parmelin and waved to reporters.
The Swiss president welcomed the two leaders, wishing them “fruitful dialogue in the interest of your two countries and the whole world.” He then stepped aside, allowing Mr. Biden and Mr. Putin to approach each other, smiling, and shake hands.
Russian officials on Wednesday sought to put a positive last-minute spin on the meeting.
“This is an extremely important day,” a deputy foreign minister, Sergey Ryabkov, told the RIA Novosti state news agency hours before the summit’s start. “The Russian side in preparing for the summit has done the utmost for it to turn out positive and have results that will allow the further deterioration of the bilateral relationship to be halted, and to begin moving upwards.”
Even before Mr. Putin landed, members of his delegation had arrived at the lakeside villa where the meeting is being held. They included Foreign Minister Sergey V. Lavrov, who joined Mr. Putin in a small-group session with Mr. Biden and Secretary of State Antony J. Blinken at the start of the summit; and Valery V. Gerasimov, Russia’s most senior military officer.
Police officers from across Switzerland — the words “police,” “Polizei” and “polizia” on their uniforms reflecting the country’s multilingual cantons — cordoned off much of the center of Geneva on Wednesday.
The city’s normally bustling lakefront was off limits, and the park where President Biden and Mr. Putin were meeting was protected by razor wire and at least one armored personnel carrier.
Inside the leafy Parc la Grange, overlooking Lake Geneva, the police directed journalists to two separate press centers — one for those covering Mr. Putin, one for those covering Mr. Biden. As the reporters waited for the leaders to arrive, a Russian radio reporter went on air and intoned that Lake Geneva had become “a lake of hope.”
A storied villa on the shores of Lake Geneva is sometimes described as having “a certain sense of mystery about it,” but there was little mystery this week about why the mansion and the park surrounding it were closed off.
Visitors were coming.
The Villa la Grange, an 18th-century manor house at the center of Parc la Grange, was the site of the meeting on Wednesday between President Biden and President Vladimir V. Putin.
Set in one of Geneva’s largest and most popular parks, the site is known not just for its lush gardens, but also for its role as a setting for important moments in the struggle between war and peace.
In 1825, the villa’s library — home to over 15,000 works and the only room to retain the villa’s original decorative features — hosted dignitaries of a European gathering that aimed to help Greeks fighting for independence.
Designed by the architect Jean-Louis Bovet and completed in 1773, the villa was owned by the Lullin family and primarily used as a summer residence before it was bought by a merchant, François Favre, in 1800.
It cemented its place in history in 1864, when it was the site of a closing gala for officials who signed the original 1864 Geneva Convention, presided over by Henri Dunant, a founder of the International Red Cross. An attempt to ameliorate the ravages of war on both soldiers and civilians, it set minimum protections for people who are victims of armed conflict.
After World War II, a new draft of the conventions was signed in an attempt to address gaps in international humanitarian law that the conflict had exposed.
In 1969, Pope Paul VI, who traveled to the park to celebrate Mass for a congregation of tens of thousands, pointed to the villa’s history as he spoke about the risk of nuclear conflagration.
He spoke about the opposing forces of love and hate and called for “generous peacemakers.”
TRAPPES, France — It all began when a high-school teacher warned that Islamists had taken over the city. The teacher went on TV, issuing alarms from inside what he called a “lost city” of the French Republic. In Trappes, he said, he feared for his life.
“Trappes, it’s finished,” the teacher said. “They’ve won.”
The mayor, a strong believer in the Republic, saw the teacher on television and didn’t recognize the city he described. He knew his city, west of Paris and with a growing population of immigrants and Muslims, had problems but thought it was being falsely maligned. The mayor also happened to be a Muslim.
“The truth doesn’t matter anymore,” he said.
For a few weeks this winter, the fight pitting the mayor, Ali Rabeh, 36, against the teacher, Didier Lemaire, 55, became a media storm that, beneath the noise and accusations, boiled down to a single, angry question that runs through the culture wars rippling through France: Can Islam be compatible with the principles of the French Republic?
Lupin.” But Trappes also saw about 70 of its youths leave for jihad to Syria and Iraq, the largest contingent, per capita, from any French city.
article about Mr. Lemaire, who said he was quitting because of Islamists.
Within a few hours, a conservative politician eyeing the presidency tweeted her support for Mr. Lemaire and “all those hussars on the front line in the fight for the Republic.” Next, the far-right leader, Marine Le Pen, attacked “certain elected officials” for failing to protect the teacher from Islamists.
That the words of a virtually unknown teacher resonated so much was a sign of the times. A few months earlier, an extremist had beheaded a middle-school teacher for showing caricatures of the Prophet Muhammad in a class on free speech. President Emmanuel Macron was now pushing a bill to fight Islamism even as he pledged to nurture an “Islam of France.”
Mr. Lemaire’s words also resonated because of the outsized role in France of public schoolteachers, who are responsible for inculcating in the young the nation’s political values and culture. In the Republic’s mythology, teachers are the “hussars” — the light cavalry once used for scouting by European armies — fighting to preserve the nation’s sanctity.
In the article, Mr. Lemaire said he had been under police escort for months. Trappes’s mayor, he said, had called him an “Islamophobe and racist.” He said he was waiting for an “exfiltration” from deep inside “a city lost for good.”
Overnight, the soft-spoken, longhaired teacher, who said he preferred curling up with Seneca than going on Facebook, was issuing dire warnings on top television news shows.
“We have six months to a year,” he said, “because all these youths who are educated with the idea that the French are their enemies, they’ll take action one day.”
Mr. Lemaire arrived in Trappes, a banlieue, or suburb, in the outer orbit of Paris, two decades earlier. Once a village that grew around a millennium-old Roman Catholic parish, Trappes is now a city of 32,000.
Mr. Lemaire’s high school, La Plaine-de-Neauphle, stands at the heart of an area built to accommodate immigrant workers from France’s former colonies in the 1970s — a mixture of rent-subsidized high-rises, attractive five-story residences and a constellation of parks. The mosque is nearby. So is a market where vendors offer delicacies from sub-Saharan Africa and halal products.
Parti républicain solidariste, which espouses a hard line on France’s version of secularism, called laïcité. He now favors taking girls away from their parents, after a second warning, if the children violate laïcité rules by putting on Muslim veils during school field trips.
“We have to protect children from this manipulation,” of being used “as soldiers or as ideologues,” he said.
‘I See Myself In Them’
remarks to the newspaper Le Monde, the local préfet, the top civil servant representing the central government, praised Mr. Rabeh’s administration for its “total cooperation” in combating Islamism. The préfet also refuted the teacher’s claim to having been under a police escort.
The teacher’s story began wobbling. He admitted to the French news media, as he did to The Times, that he had “not received explicit death threats.” He had also accused the mayor of calling him a “racist and Islamophobe” in an interview with a Dutch television network.
But the network denied the mayor had said any such thing.
‘France Really Doesn’t Like Us’
letter to the students at the teacher’s high school.
“Don’t let anybody ever tell you that you’re worth nothing and that you’re lost to the Republic,” he wrote.
debate was scheduled that evening between Ms. Le Pen and Gérald Darmanin, the interior minister leading the government’s crackdown on Islamism. Hours before the debate, he announced that the teacher would be granted police protection.
That evening, Jean-Michel Blanquer, the national education minister, issued a statement supporting the teacher. He also accused the mayor of trespassing into the high school to distribute tracts — the letter — that morning. “Political and religious neutrality is at the heart of the operation of the School of the Republic,” the minister said.
The city officials at the school that morning told The Times that no copies were distributed inside. The regional education office and Mr. Blanquer’s office refused to make the school principal available for an interview. The minister’s office declined to comment.
The trespassing accusations led to such an avalanche of threats against the mayor that he, too, was put under police protection — a shared destiny, for a while, for the two men of Trappes, who had each lost something.
The teacher was forced to leave the school where he had taught for 20 years and, despite his criticisms of Trappes, said “you really feel you’re on a mission.” He said he should have been more careful with the facts and had made “many mistakes,” but stuck by his interpretation of Trappes as “lost.”
His words, he said, had led to a “clarification of positions today in France.”
The mayor questioned the very Republic that once inspired him. He had believed that “the people who embody the Republic will come, the government will eventually express its solidarity with me.”
“Stunned,” he said, “I find that’s not the case.”
He declined his worried father’s request to resign.
“For a moment during the crisis, I told myself, well, if this is the Republic, I’m abandoning the Republic, just as it’s abandoned me,” Mr. Rabeh said. “But the truth is they’re not the Republic. The kids of Trappes are the Republic.”
SAN FRANCISCO — When India’s government ordered Facebook and other tech companies to take down posts critical of its handling of the coronavirus pandemic in April, the social network complied on some posts.
But once it did, its employees flocked to online chat rooms to ask why Facebook had helped Prime Minister Narendra Modi of India stifle dissent. In one internal post, which was reviewed by The New York Times, an employee with family in India accused Facebook of “being afraid” that Mr. Modi would ban the company from doing business in the country. “We can’t act or make decisions out of fear,” he wrote.
Weeks later, when clashes broke out in Israel between Israelis and Palestinians, Facebook removed posts from prominent Palestinian activists and briefly banned hashtags related to the violence. Facebook employees again took to the message boards to ask why their company now appeared to be censoring pro-Palestinian content.
“It just feels like, once again, we are erring on the side of a populist government and making decisions due to politics, not policies,” one worker wrote in an internal message that was reviewed by The Times.
inflammatory posts from former President Donald J. Trump. But since Mr. Trump left office in January, attention has shifted to Facebook’s global policies and what employees said was the company’s acquiescence to governments so that it could continue profiting in those countries.
“There’s a feeling among people at Facebook that this is a systematic approach, one which favors strong government leaders over the principles of doing what is right and correct,” said Ashraf Zeitoon, Facebook’s former head of policy for the Middle East and North Africa region, who left in 2017.
Facebook is increasingly caught in a vise. In India, Russia and elsewhere, governments are pressuring it to remove content as they try to corral the platform’s power over online speech. But when Facebook complies with the takedown orders, it has upset its own employees, who say the social network has helped authoritarian leaders and repressive regimes quash activists and silence marginalized communities.
BuzzFeed News and the Financial Times earlier reported on some of the employee dissatisfaction at Facebook over Israeli and Palestinian content.
A divide between Facebook’s employees and the global policy team, which is composed of roughly 1,000 employees, has existed for years, current and former workers said. The policy team reports to Sheryl Sandberg, the chief operating officer.
many tricky international situations over the years, including in Russia, Vietnam and Myanmar, where it has had to consider whether it would be shut down if it did not work with governments. That has led to the employee dissent, which has begun spilling into public view.
That became evident with India. In April, as Covid-19 cases soared in the country, Mr. Modi’s government called for roughly 100 social media posts on Facebook, Instagram and Twitter to be pulled down. Many of the posts included critiques of the government from opposition politicians and calls for Mr. Modi’s resignation.
Facebook removed some of the posts and briefly blocked a hashtag, #ResignModi. The company later said the hashtag had been banned by mistake and was not part of a government request.
But internally, the damage was done. In online chat rooms dedicated to human rights issues and global policy, employees described how disappointed they were with Facebook’s actions. Some shared stories of family members in India who were worried they were being censored.
Last month, when violence broke out between Israelis and Palestinians, reports surfaced that Facebook had erased content from Palestinian activists. Facebook’s Instagram app also briefly banned the #AlAqsa hashtag, a reference to Al Aqsa Mosque, one of Islam’s holiest sites. Facebook later explained that it had confused the #AlAqsa hashtag with a Palestinian militant group called Al Aqsa Martyrs Brigade.

Employees bristled. “We are responding to people’s protests about censoring with more censoring?” one wrote in an internal message, which was reviewed by The Times.
Nick Clegg, who leads public affairs, to explain the company’s role in removing content tied to the Israeli-Palestinian conflict, according to attendees. The employee called the situation in Israel “fraught” and asked how Facebook was going “to get it right” with content moderation.
Mr. Clegg ran through a list of policy rules and plans going forward, and assured staff that moderation would be treated with fairness and responsibility, two people familiar with the meeting said. The discussion was cordial, one of the people said, and comments in the chat box beside Mr. Clegg’s response were largely positive.
But some employees were dissatisfied, the people said. As Mr. Clegg spoke, they broke off into private chats and workplace groups, known as Tribes, to discuss what to do.
Dozens of employees later formed a group to flag the Palestinian content that they said had been suppressed to internal content moderation teams, said two employees. The goal was to have the posts reinstated online, they said.
Members of Facebook’s policy team have tried calming the tensions. In an internal memo in mid-May, which was reviewed by The Times, two policy team members wrote to other employees that they hoped “that Facebook’s internal community will resist succumbing to the division and demonization of the other side that is so brutally playing itself out offline and online.”
One of them was Muslim, and the other was Jewish, they said.
“We don’t always agree,” they wrote. “However, we do some of our best work when we assume good intent and recognize that we are on the same side trying to serve our community in the best possible way.”
Famine is now knocking on the door of Ethiopia’s Tigray region, where a civil war that erupted last year has drastically cut the food supply and prevented relief workers from helping the hungry, the top U.N. humanitarian official has warned.
In a confidential note to the United Nations Security Council, the official, Mark Lowcock, the under secretary general for humanitarian affairs, said sections of Tigray, a region of more than 5 million people, are now one step from famine — in part because the government has obstructed aid shipments.
The note, seen by The New York Times, was submitted Tuesday under a Security Council resolution requiring such notification when conflicts cause famine and widespread food insecurity.
“These circumstances now arise in the Tigray region of Northern Ethiopia,” Mr. Lowcock said in the note. While below-average rain, locusts and the Covid-19 pandemic have all contributed to food scarcity, he said, “the scale of the food crisis Tigray faces today is a clear result of the conflict and the behavior of the parties.”
since last November. Prime Minister Abiy Ahmed and neighboring Eritrea ordered their military forces into the region to crush Mr. Abiy’s political rivals and strengthen his control.
What Mr. Abiy, a Nobel Peace Prize laureate, predicted would be a short operation has instead become a quagmire that threatens to destabilize the Horn of Africa. Ethiopian and Eritrean troops have been accused of ethnic cleansing, massacres and others atrocities in Tigray that amount to war crimes.
While the United Nations and international relief organizations have achieved some cooperation from the Ethiopian authorities in gaining access to deprived areas of Tigray, Mr. Lowcock said in his note, such cooperation has deteriorated in recent months. “Humanitarian operations are being attacked, obstructed or delayed in delivering lifesaving assistance,” he wrote, and at least eight aid workers have been killed.
“As a result of impediments and the effect of restrictions, not nearly enough support is being provided,” he wrote. He urged Security Council members “to take any steps possible to prevent a famine from occurring.”
His warning was echoed by Samantha Power, the administrator of the United States Agency for International Development, the main U.S. government provider of humanitarian assistance to needy countries. Ms. Power, a former American ambassador to the United Nations, said in a statement that one of the aid workers killed had worked for the agency she now runs.
took the unusual step of penalizing Ethiopia over growing American exasperation with Mr. Abiy’s actions in Tigray. Secretary of State Antony J. Blinken announced visa restrictions on officials linked to the conflict, preventing their travel to the United States.
Ethiopia’s Foreign Ministry reacted angrily, calling the restrictions “extremely regrettable” and suggesting they would “seriously undermine this longstanding and important bilateral relationship.”
Immunity to the coronavirus lasts at least a year, possibly a lifetime, improving over time especially after vaccination, according to two new studies. The findings may help put to rest lingering fears that protection against the virus will be short-lived.
Together, the studies suggest that most people who have recovered from Covid-19 and who were later immunized will not need boosters. Vaccinated people who were never infected most likely will need the shots, however, as will a minority who were infected but did not produce a robust immune response.
Both reports looked at people who had been exposed to the coronavirus about a year earlier. Cells that retain a memory of the virus persist in the bone marrow and may churn out antibodies whenever needed, according to one of the studies, published on Monday in the journal Nature.
The other study, which is also under review for publication in Nature, found that these so-called memory B cells continue to mature and strengthen for at least 12 months after the initial infection.
Some scientists have interpreted this decrease as a sign of waning immunity, but it is exactly what’s expected, other experts said. If blood contained high quantities of antibodies to every pathogen the body had ever encountered, it would quickly transform into a thick sludge.
Instead, blood levels of antibodies fall sharply following acute infection, while memory B cells remain quiescent in the bone marrow, ready to take action when needed.
landmark study in 2007 showed that antibodies in theory could survive decades, perhaps even well beyond the average life span, hinting at the long-term presence of memory B cells. But the new study offered a rare proof of their existence, Dr. Gommerman said.
Dr. Nussenzweig’s team looked at how memory B cells mature over time. The researchers analyzed blood from 63 people who had recovered from Covid-19 about a year earlier. The vast majority of the participants had mild symptoms, and 26 had also received at least one dose of either the Moderna or the Pfizer-BioNTech vaccine.
So-called neutralizing antibodies, needed to prevent reinfection with the virus, remained unchanged between six and 12 months, while related but less important antibodies slowly disappeared, the team found.
confirming results from other studies; the shots also ramped up the body’s neutralizing ability by about 50-fold.
Senator Rand Paul, Republican of Kentucky, said on Sunday that he would not get a coronavirus vaccine because he had been infected in March of last year and was therefore immune.
But there is no guarantee that such immunity will be powerful enough to protect him for years, particularly given the emergence of variants of the coronavirus that can partially sidestep the body’s defenses.
The results of Dr. Nussenzweig’s study suggest that people who have recovered from Covid-19 and who have later been vaccinated will continue to have extremely high levels of protection against emerging variants, even without receiving a vaccine booster down the line.
“It kind of looks exactly like what we would hope a good memory B cell response would look like,” said Marion Pepper, an immunologist at the University of Washington in Seattle who was not involved in the new research.
The experts all agreed that immunity is likely to play out very differently in people who have never had Covid-19. Fighting a live virus is different from responding to a single viral protein introduced by a vaccine. And in those who had Covid-19, the initial immune response had time to mature over six to 12 months before being challenged by the vaccine.
“Those kinetics are different than someone who got immunized and then gets immunized again three weeks later,” Dr. Pepper said. “That’s not to say that they might not have as broad a response, but it could be very different.”
JERUSALEM — Israel will launch a “very powerful” response to any new attacks by Hamas militants, Prime Minister Benjamin Netanyahu warned on Tuesday, thanking the United States for bolstering his country’s air defenses during a visit by the top American diplomat that sought to promote peace.
Secretary of State Antony J. Blinken, in his first trip to the Middle East during the Biden administration, was met by a country on edge following more than 10 days of war with Hamas that ended with a tenuous cease-fire late last week.
In brief but blunt comments after their private meeting, Mr. Netanyahu said he was grateful that the Biden administration consistently affirmed Israel’s right to defend itself after coming under rocket attack by militants in the Gaza Strip. He said he and Mr. Blinken had discussed how to curb Hamas, which controls Gaza, and how to help rebuild and otherwise improve the lives of the two million Palestinians who live there.
“If Hamas breaks the calm and attacks Israel, our response will be very powerful,” Mr. Netanyahu told reporters after the meeting, standing next to Mr. Blinken.

rebuild our relationship” with the Palestinian people and the Palestinian Authority. He was to meet later Tuesday in Ramallah with President Mahmoud Abbas and Prime Minister Mohammad Shtayyeh of the Palestinian Authority.
In seeking to prop up the authority, the Biden administration aims to sideline Hamas, the militant group that controls Gaza, which the United States considers a terrorist organization. Hamas and the Palestinian Authority are bitter political rivals, and it is far from assured that the militants will cede any of their grip over Gaza.
In a series of discussions with Mr. Blinken throughout the afternoon, Mr. Netanyahu and other Israeli officials also homed in on what they described as another urgent threat to their stability: Iran.
With American and Iranian diplomats separately meeting with world powers in Vienna, officials have in recent days noted progress in negotiations to bring both sides back into compliance with a 2015 nuclear deal.
the Trump administration jettisoned in 2018, in hopes of imposing stricter limits on Iran’s nuclear, missile and military programs.
Mr. Netanyahu said the original deal “paves the way for Iran to have an arsenal of nuclear weapons.”
riots erupted at Al Aqsa Mosque in Jerusalem, one of the holiest sites in Islam.
“We believe that Palestinians and Israelis equally deserve to live safely and securely to enjoy equal measures of freedom opportunity, and democracy, to be treated with dignity,” Mr. Blinken said.
“Healing these wounds will take leadership at every level of society,” he said.
NAIROBI, Kenya — Growing American frustration over the war in the Tigray region of Ethiopia spilled over into an open confrontation on Monday when Ethiopian officials lashed out at Washington over new restrictions including aid cuts and a ban on some Ethiopians traveling to the United States.
The restrictions, announced by Secretary of State Antony J. Blinken on Sunday, amount to an unusual step against a key African ally, and a pointed rebuke to Prime Minister Abiy Ahmed, a Nobel Peace Prize winner whose troops and allies have been accused of ethnic cleansing, massacres and others atrocities that could amount to war crimes.
Despite “significant diplomatic engagement,” Mr. Blinken said in a statement, “the parties to the conflict in Tigray have taken no meaningful steps to end hostilities or pursue a peaceful resolution of the political crisis.”
American visa restrictions will apply to all actors in the Tigray conflict, Mr. Blinken said, including current and former Ethiopian and Eritrean officials, ethnic Amhara militias and Tigrayan rebels.
a statement on Monday, Ethiopia’s foreign affairs ministry reacted with an expression of regret and what appeared to be thinly veiled threats. It accused the United States of meddling in its internal affairs and trying to overshadow national elections scheduled for June 21.
And it said that Ethiopia could be “forced to reassess its relations with the United States, which might have implications beyond our bilateral relationship.”
gave $923 million, according to USAID, although the vast majority of that money was for humanitarian purposes — health care, food aid, education and democracy support — that will not be hit by the new measures.
The United States had already suspended $23 million in security aid to Ethiopia. Officials say the new measures will preclude any American arms sales to Ethiopia, although much of the country’s weapons come from Russia.
Still, there could be other impacts. Western diplomats say the United States could block international funding to Ethiopia from the World Bank and International Monetary Fund — integral to Mr. Abiy’s economic plans.
dispatched by President Biden in March, and Jeffrey Feltman, the recently appointed Horn of Africa envoy.
American officials worry that the growing chaos in Tigray could destabilize the entire Horn of Africa region, or jeopardize efforts to mediate a high-stakes dispute with Egypt over the massive hydroelectric dam that Ethiopia is building on the Nile.
The growing humanitarian crisis, including the threat of a famine within months, is also driving the sense of urgency.
Those responsible for the Tigray crisis “should anticipate further actions from the United States and the international community,” Mr. Blinken said. “We call on other governments to join is taking these measures.”
After graduating in 1953, Mr. Yuan took a job as a teacher in an agricultural college in Hunan Province, keeping up his interest in crop genetics. His commitment to the field took on greater urgency from the late 1950s, when Mao’s so-called Great Leap Forward — his frenzied effort to collectivize agriculture and jump-start steel production — plunged China into the worst famine of modern times, killing tens of millions. Mr. Yuan said he saw the bodies of at least five people who had died of starvation by the roadside or in fields.
“Famished, you would eat whatever there was to eat, even grass roots and tree bark,” Mr. Yuan recalled in his memoir. “At that time I became even more determined to solve the problem of how to increase food production so that ordinary people would not starve.”
Mr. Yuan soon settled on researching rice, the staple food for many Chinese people, searching for hybrid varieties that could boost yields and traveling to Beijing to immerse himself in scientific journals that were unavailable in his small college. He plowed on with his research even as the Cultural Revolution threw China into deadly political infighting.
In recent decades, the Communist Party came to celebrate Mr. Yuan as a model scientist: patriotic, dedicated to solving practical problems, and relentlessly hard-working even in old age. At 77, he even carried the Olympic torch near Changsha for a segment of its route to the Beijing Olympics in 2008.
Unusually for such a prominent figure, though, Mr. Yuan never joined the Chinese Communist Party. “I don’t understand politics,” he told a Chinese magazine in 2013.
Even so, the Xinhua state news agency honored him this weekend as a “comrade,” and his death brought an outpouring of public mourning in China. In 2019, he was one of eight Chinese individuals awarded the Medal of the Republic, China’s highest official honor, by Xi Jinping, the national leader.
Mr. Yuan is survived by his wife of 57 years, Deng Zhe, as well as three sons. His funeral, scheduled for Monday morning in Changsha, is likely to bring a new burst of official condolences.
All over the world, countries are confronting population stagnation and a fertility bust, a dizzying reversal unmatched in recorded history that will make first-birthday parties a rarer sight than funerals, and empty homes a common eyesore.
Maternity wards are already shutting down in Italy. Ghost cities are appearing in northeastern China. Universities in South Korea can’t find enough students, and in Germany, hundreds of thousands of properties have been razed, with the land turned into parks.
Like an avalanche, the demographic forces — pushing toward more deaths than births — seem to be expanding and accelerating. Though some countries continue to see their populations grow, especially in Africa, fertility rates are falling nearly everywhere else. Demographers now predict that by the latter half of the century or possibly earlier, the global population will enter a sustained decline for the first time.
A planet with fewer people could ease pressure on resources, slow the destructive impact of climate change and reduce household burdens for women. But the census announcements this month from China and the United States, which showed the slowest rates of population growth in decades for both countries, also point to hard-to-fathom adjustments.
spirals exponentially. With fewer births, fewer girls grow up to have children, and if they have smaller families than their parents did — which is happening in dozens of countries — the drop starts to look like a rock thrown off a cliff.
“It becomes a cyclical mechanism,” said Stuart Gietel Basten, an expert on Asian demographics and a professor of social science and public policy at the Hong Kong University of Science and Technology. “It’s demographic momentum.”
Some countries, like the United States, Australia and Canada, where birthrates hover between 1.5 and 2, have blunted the impact with immigrants. But in Eastern Europe, migration out of the region has compounded depopulation, and in large parts of Asia, the “demographic time bomb” that first became a subject of debate a few decades ago has finally gone off.
South Korea’s fertility rate dropped to a record low of 0.92 in 2019 — less than one child per woman, the lowest rate in the developed world. Every month for the past 59 months, the total number of babies born in the country has dropped to a record depth.
schools shut and abandoned, their playgrounds overgrown with weeds, because there are not enough children.
To goose the birthrate, the government has handed out baby bonuses. It increased child allowances and medical subsidies for fertility treatments and pregnancy. Health officials have showered newborns with gifts of beef, baby clothes and toys. The government is also building kindergartens and day care centers by the hundreds. In Seoul, every bus and subway car has pink seats reserved for pregnant women.
But this month, Deputy Prime Minister Hong Nam-ki admitted that the government — which has spent more than $178 billion over the past 15 years encouraging women to have more babies — was not making enough progress. In many families, the shift feels cultural and permanent.
projections by an international team of scientists published last year in The Lancet, 183 countries and territories — out of 195 — will have fertility rates below replacement level by 2100.
municipalities have been consolidated as towns age and shrink. In Sweden, some cities have shifted resources from schools to elder care. And almost everywhere, older people are being asked to keep working. Germany, which previously raised its retirement age to 67, is now considering a bump to 69.
Going further than many other nations, Germany has also worked through a program of urban contraction: Demolitions have removed around 330,000 units from the housing stock since 2002.
recently increased to 1.54, up from 1.3 in 2006. Leipzig, which once was shrinking, is now growing again after reducing its housing stock and making itself more attractive with its smaller scale.
“Growth is a challenge, as is decline,” said Mr. Swiaczny, who is now a senior research fellow at the Federal Institute for Population Research in Germany.
Demographers warn against seeing population decline as simply a cause for alarm. Many women are having fewer children because that’s what they want. Smaller populations could lead to higher wages, more equal societies, lower carbon emissions and a higher quality of life for the smaller numbers of children who are born.
But, said Professor Gietel Basten, quoting Casanova: “There is no such thing as destiny. We ourselves shape our lives.”
The challenges ahead are still a cul-de-sac — no country with a serious slowdown in population growth has managed to increase its fertility rate much beyond the minor uptick that Germany accomplished. There is little sign of wage growth in shrinking countries, and there is no guarantee that a smaller population means less stress on the environment.
Many demographers argue that the current moment may look to future historians like a period of transition or gestation, when humans either did or did not figure out how to make the world more hospitable — enough for people to build the families that they want.
Surveys in many countries show that young people would like to be having more children, but face too many obstacles.
Anna Parolini tells a common story. She left her small hometown in northern Italy to find better job opportunities. Now 37, she lives with her boyfriend in Milan and has put her desire to have children on hold.
She is afraid her salary of less than 2,000 euros a month would not be enough for a family, and her parents still live where she grew up.
“I don’t have anyone here who could help me,” she said. “Thinking of having a child now would make me gasp.”

Germany is banning most travel from Britain starting on Sunday amid concerns about the spread of a coronavirus variant first discovered in India, the German authorities said on Friday.
German citizens and residents of Germany will still be allowed to enter the country from Britain but will be required to self-isolate for two weeks upon arrival, Germany’s public health institution said as it classified Britain as an area of concern because of the variant.
The move came just days after Britain reopened its museums and cinemas and resumed allowing indoor service in pubs and restaurants. Many people in Britain have been looking forward to traveling abroad in the coming months, and Spain is set to welcome visitors arriving from Britain without a coronavirus test starting on Monday.

This month, the World Health Organization declared the mutation a “variant of concern,” and although scientists’ knowledge about it remains limited, it is believed to be more transmissible than the virus’s initial form.
dozen or so other countries that Germany considers areas of concern because of variants. As of Thursday, Britain had 3,424 cases of the variant first discovered in India, according to government data, up from 1,313 cases the previous week.
Dozens of nations, including European countries and the United States, suspended travel from Britain or imposed strict restrictions earlier in the pandemic amid concerns about the spread of a variant first detected in England.
Britain’s Office for National Statistics said on Friday that the percentage of people testing positive for the coronavirus in England had showed “early signs of a potential increase” in the week ending May 15, although it said rates remained low compared with earlier this year. At its peak in late December, Britain recorded more than active 81,000 cases, compared with about 2,000 this month.
The country’s inoculation campaign is continuing apace, with an increased focus on second doses in an effort to thwart the sort of spikes that led to restrictions imposed earlier this year.

Prime Minister Boris Johnson has vowed to proceed with a plan to lift all restrictions by June 21, although scientists have warned that the spread of the B.1.617 variant could delay such plans. Most cases of the variant have been found in northwestern England, with some in London.
In Germany, the restrictions on travel from Britain come as outdoor service resumed on Friday in cafes, restaurants and beer gardens after months of closure. Chancellor Angela Merkel urged people to “treat these opportunities very responsibly.”
