The good news is PresidentDonald Trumpis determined tomake a deal, and fast, to end the grindingwar in Ukraine. For theleaders of Ukraine and Europe, that could be the bad news, too. Concern about whatTrump would be willing to cede to Russiain his supercharged effort to reach an accord − the prime exhibit in hisopen campaign to win the Nobel Peace Prize− drew an extraordinary group of European leaders to the White House to back upUkrainian President Volodymyr Zelenskyyat a pivotal moment for Kyiv.

ButRussian President Vladimir Putinruled out a ceasefire at his ownmeeting with Trump,this one in Alaskathree days earlier, and he apparently won him over. Facing aunited front from NATO and the European Community, from the leaders of France and Germany and Great Britain, Trump on Monday found himself more closely aligned with Moscow on this key question. On his way to Alaska, Trump had called a ceasefire crucial, threatening "serious consequences" if Russia didn't agree. But after Putin's flatnyet,Trump in the East Room described a ceasefire as a nice idea but not an imperative. More:Trump and Zelenskyy meet again, but Putin has faced Trump, other presidents many times Trump said the United States wasprepared to participatein security guarantees for Ukraine, a significant step and one Putin indicated a willingness to consider. That surely increases the pressure on Zelenskyy to agree to what Trump calls "land swaps," perhaps including giving away territory Russia has not yet won on the battlefield. Putin has demanded the Donbas, an area rich in industry and strategically located. Zelenskyy has rejected the idea of ceding any land. The whirlwind of developments in the space of a few days was a telling display of foreign policy in the age of Trump 2.0. For one thing, the tradition of slow-as-you-go diplomacy, of meticulous meetings by aides to hash out the details before the principals meet, has been replaced by sweeping declarations from the top − often streamed live to the world and updated in real time on Truth Social. For another, any inclination by foreign leaders during Trump's first term to challenge him too directly has been replaced by a strategy of flattery. More:A Nobel Peace Prize for Trump? World leaders are lining up That's true for Putin. He is a former KGB agent who has led the Kremlin with an iron hand for a quarter-century. But on this, Putin has persuaded Trump that he has Trump's own interests at heart. "I think he wants to make a deal for me," Trump told French President Emmanuel Macron as they gathered for a group photo in the White House Cross Hall, a private aside picked up by a hot mic. "Do you understand? As crazy as it sounds." It's true forZelenskyy,who showed up at the White House ina dark suit− a concession to Trump's complaints about hisusual military-style attireat his last visit. That encounterimploded into acrimony.In the Oval Office this time, he heaped praise on the president. "Thank you very much for your efforts," he told Trump. Vice PresidentJD Vance, who had laced into Zelenskyy in February's meeting for ingratitude, sat on the couch next to the president, silent and smiling. It was apparent among the European leaders, too. NATO Secretary-General Mark Rutte launched a round-robin of praise." "I really want to thank you, President of the United States, dear Donald," he said, crediting him with "breaking the deadlock" on the war and "starting the dialogue" for peace. More:Ukraine's Zelenskyy avoids Trump mauling at White House. Will he get Putin meeting? Zelenskyy and other leaders expressed particular appreciation for Trump's willingness to support security guarantees, though European forces would be expected to take the lead and the U.S. role hasn't been defined. German Chancellor Friedrich Merz raised the most direct caution of the day. "The next steps are the more complicated ones," he said, adding: "I can't imagine that the next meeting would take place without a ceasefire." Just when and where that next meeting would take place isn't clear, but Merz later told reporters it was supposed to happen within the next two weeks. Trump had "paused" his conversation with the European leaders to hold a 40-minute phone call with Putin. Afterward, he said he"began the arrangements" for a meeting, at a location to be determined, between Putin and Zelenskyy. "After that meeting takes place, we will have a Trilat, which would be the two Presidents, plus myself," he said in a social media post. Skeptics warn that Putin is playing for time, for the opportunity tokeep hammering Ukraineon the battlefield while giving lip service to seeking peace. Putin has another long-standing goal, too: to drive a wedge in the Western alliance that was forged in the aftermath of World War II, in large part as a check on Moscow. An expansionist Russia and a divided alliance is also the European leaders' greatest fear − not only for Ukraine's sake but also for their own. "The optimism of your president is to be taken seriously," Macron told NBC after he left the White House. But he expressed little of Trump's confidence in his new peace partner: "When I look at the situation and the facts, I don't see President Putin very willing to get peace now."
