Where There’s Smoke, There’s a Conspiracy Theory at a Russian Consulate

The smoke was first spotted around noon on Friday. Neighbors called the Fire Department.“We responded as if it were a fire,” said a Fire Department spokeswoman, Mindy Talmadge. “When we got to the consulate, we confirmed that it was coming from the chimney.”With a layer of smoke haze covering the bay from wildfires in Northern California, Friday had been declared a “Spare the Air Day,” when residents are urged to cut back on activities that cause pollution. As images of the consulate smoke circulated on social media, the Bay Area Air District tweeted that it was taking action.“I have no idea what they are burning,” said Lisa Fasano, a spokeswoman for the air district, which enforces and regulates air quality in the nine-county region. “But we are having poor air quality out here right now. We need to do everything we can to protect our air.”Ms. Fasano said the inspector patrolled the neighborhood and took pictures […]

Russians Call Putin’s Trump Meeting Win, but Doubt Concrete Gains

One Russian tabloid called the meeting “historic,” and over all there was a sense of relief that if short on concrete agreements, the talks seemed to halt the downward spiral in relations and lack of contact between the two countries.Continue reading the main storyThis meeting “opened the way to a second, a third, a fourth meeting, where meaningful decisions will be made,” Sergei Markov, a political commentator close to the Kremlin, wrote on Facebook. He hailed the return to “normal contacts,” which he said had been destroyed by Mr. Obama, who sought to isolate Russia after it seized Crimea in March 2014.Amid the cheering in Moscow, however, there were notes of caution about the frequent gaps between what Mr. Trump says and what he does and can deliver. And more important, there was a recognition that the domestic mood toward Russia in the United States remained sour.The main message that emerged after more than two hours of talks on the sidelines of the Group of 20 summit meeting in Hamburg on Friday was that deals were possible, analysts said, and the mere fact that the two presidents had met in person for the first time since Mr. Trump was elected mattered more than the lack of a breakthrough.“It is important that they finally met because if you look at the history of the relations between Washington and Moscow, these relations always depended to a large extent on the personal contact between the two leaders,” said Andrei V. Kortunov, the director of the Russian International Affairs Council, a foreign policy research group, in an interview […]

Trump Questions Putin on Election Meddling at Eagerly Awaited Encounter

Mr. Trump, according to Mr. Lavrov, “mentioned that certain circles in the U.S. are still exaggerating, although they cannot prove this, the topic of Russia’s interference with the U.S. election.”Both sides agreed that the two leaders had been eager to pivot from the dispute and discuss other matters, including a new effort to combat cyberthreats and a cease-fire to begin as early as Sunday in a limited area of southwestern Syria.While such a step in Syria would be small, it appeared to reflect a desire by American and Russian officials to move past their tense flare-ups over the Syria conflict and facilitate a way to end the six-year civil war there. Moscow has been backing the government of President Bashar al-Assad of Syria while the United States has sought to aid opposition groups fighting to oust him.Newsletter Sign UpContinue reading the main storyThank you for subscribing.An error has occurred.

Donald Trump, in Poland, Urges West to ‘Defend Our Civilization’

Mr. Trump also decried “the steady creep of government bureaucracy that drains the vitality and wealth of the people,” citing the value of individual freedom and sovereignty, in front of an audience that was composed in part of loyalists bused in for the occasion.Continue reading the main story“Poland will prevail,” he said, citing the country’s centuries-long history of endurance in the face of invasion, partition, Nazi occupation and communist domination. “Poland will always prevail.”Mr. Trump had harsh words for North Korea after its recent test of a new long-range missile, but he refused to say during a short news conference with the Polish president, Andrejz Duda, what steps he would take to punish Pyongyang.He said earlier on Thursday that he was weighing “some pretty severe things” to respond to the North Korean nuclear threat, and he called on all nations to confront what he called the “global threat” from Pyongyang.“We’ll see what happens — I don’t like to talk about what we have planned — but I have some pretty severe things that we’re thinking about,” Mr. Trump said at the news conference. “They are behaving in a very, very serious manner, and something will have to be done about it.”PhotoFriendly crowds gathered to listen to Mr. Trump’s speech.Credit Stephen Crowley/The New York TimesMr. Trump — who is under pressure to confront Mr. Putin on his attempts to sway the election — delivered a mixed message on Russia, one tailored for his Polish audience, the other straight out of his Putin playbook.The president, acknowledging Polish concerns about Russia’s intervention in Ukraine, said, “We are working with Poland” to deal with “Russia’s destabilizing behavior.”But he said he was still not entirely convinced that Russia was solely responsible for interference in the 2016 election, breaking with American intelligence agencies that have agreed that the efforts emanated from Moscow and were directed by Mr. […]

Trump to Meet With Putin at G-20 Gathering Next Week

The encounter could have broad implications for American foreign policy. But it is also fraught with political overtones for Mr. Trump, who is under scrutiny about his willingness to be tough on Moscow after a campaign in which he praised Mr. Putin effusively and exhorted Russia — in what his aides now call a joke — to hack into Hillary Clinton’s email.Continue reading the main storyCongressional committees and a special counsel are digging more deeply into possible ties between the president’s campaign and Moscow. But Mr. Trump has repeatedly cast doubt on the unanimous conclusion of United States intelligence agencies that Russia sought to interfere in the 2016 race, often describing the assertion as a hoax perpetrated to undermine his presidency.Yet even as the Trump administration has sought to develop friendlier ties with Russia, the relationship is under continued strain over Moscow’s seizure of Crimea and interference in Ukraine. It has also proved awkward for Mr. Trump amid recent revelations about the extent to which Mr. Putin personally directed cyberintrusions into the election.General McMaster said the president had directed his team to devise ways of confronting “Russia’s destabilizing behavior,” whether through cyberthreats or political subversion in the United States or elsewhere, and to deter conflicts.“Nobody wants a major-power war,” General McMaster told reporters. He also said Mr. […]
