KHARKIV, Ukraine — Even as his family sobbed into the dirt of his brother's grave, Ukrainian soldier Artem Reshetilov warned President Donald Trump that he should not compromise with Russia duringFriday's peace talks in Alaska. His brother, Andrei, 38, was killed by a Russian artillery strike while fighting to defend Ukraine's frontlines. At the funeral on the eve ofthe talks in Anchorage— to which Ukraine has not been invited — Reshetilov urged Trump not to bend toVladimir Putin's demandsof more Ukrainian land. "We don't have to compromise with the enemy and give up our beloved land because this enemy won't stop," said Reshetilov, 46, as hundreds of Ukrainian flags, each marking the grave of a fallen soldier, flapped in the breeze behind him at this cemetery near the major northern city of Kharkiv. Like manywho will not be present in Anchorage, he told NBC News he fears Russia could merely use a ceasefire to "return even stronger" and attack Ukraine and even other countries in Europe. "We know Russia and they never keep agreements," he added. These fears are not confined just to Ukrainian hearts but shared by governments, experts and people across Europe and beyond who fear what Trump might agree with Putinin a bid to resolve a warhe once promised the American people he could fix in 24 hours. Follow live updates here Alarmed at being frozen out of the talks, Ukrainian President Volodymyr Zelenskyy and his government this week turned to European leaders for a lifeline, hoping to influence the high-stakes summit and prevent a potential disaster for Ukraine. A flurry of diplomacy culminated with a Wednesday emergency video call between Trump, Zelenskyy, and leaders from Britain, France, Germany, the European Union and NATO, all of whomurged the American president not to capitulate to Putin. Trump said afterward that he had assured them there would be "very severe consequences" if Putin did not agree to end the war. U.S. allies came away hopeful they had steered the president away from a potential Putin diplomatic trap, but nonetheless anxious, European diplomats and former U.S. officials said. "It's looking better today than it did a week ago," said William Taylor, a former U.S. ambassador to Ukraine. "The Ukrainians and the Europeans were all worried that Trump and Putin would get together and make some decisions for Ukraine." Even so, the apprehension is palpable. "We all are preparing ourselves for an outcome that may be highly problematic," said one European official who spoke on condition of anonymity due to the sensitivity of the talks. So far, Ukrainian officials and European allieshave tried to tread carefullyto avoid antagonizing Trump. But if the talks produce a lop-sided proposal favoring Russia, "then there is no way that Europe can simply pretend that everything is simply ok," the European official said. Asked for a response to these criticisms, the White House directed NBC News to statements Trump has made this week saying that it would be up to Ukraine and Russia to make a deal between them, and that this meeting was merely a "listening exercise" that could lead to an eventual summit between the warring leaders. Trump said Thursday that Putin was "not going to mess around with me," but added that he "will be very proud to end this war" along with several others he claims to have helped resolve, calling himself the "peacemaker-in-chief." What's caused the most consternation in Ukraine is Trump's repeated suggestions thathe could negotiate a "land swap" between Russia and Ukraine, having previously suggested it would be unrealistic for Ukrainians to expect the return of lands illegally invaded and currently occupied by Russia. The American president told European leaders this week that he would not discuss territory divisions during his sit-down with Putin,two European officials and three other people briefed on the call told NBC News. That's not to say opinion in Ukraine hasn't shifted. A survey bypollster Gallup this monthsuggested the public now favors a negotiated solution — thoughthe majority still rejectRussia's absolutist terms. Regardless of what Trump and Putin discuss, Ukraine's absence renders the entire exercise absurd and insulting for many in the country actually under attack. "Why should they talk about Ukraine without Ukraine's participation?" said Oksana Andrusyak, 26, who works as a communications analyst in the Ukrainian capital. She expects such from Putin, a man wanted for war crimes by the International Criminal Court. "But why does the United States, which positions itself as a state that values the rule of law," she asked, want to take part in what she calls a "circus?" Putin has said he is ready for peace — but only if Ukraine essentially surrenders. Rather than showing willingness to wind up his war, he is killing more Ukrainian citizens than ever. July saw more civilian casualties than any other month during the war — 286 people killed and 1,388 injured — the United Nations announced last month. The attritional losses on the frontlines are also piling up. NBC News' interview with Artem Reshetilov at his brother's graveside was interrupted by another funeral filing into the cemetery immediately after, soon to be a new flag driven into a fresh mound of soil. The past week has illustrated how Ukraine may now see Europe — not the United States —as its primary partner and advocate, with European powers increasingly taking the lead in military and financial assistance and imposing sanctions on Moscow, experts and former U.S. officials said. "If the US is backtracking, someone has to come in, otherwise it's an open flank for Putin, " said Christian Forstner, director of the Hanns Seidel Foundation in Washington, a German nonprofit. The run-up to the summit underscored how both Russia and Ukraine are competing to win Trump over and persuade him of their case, and that the American president appears to have no fixed position, European officials and experts said. Europe sees this as being about Ukraine but also so much more. They believe that rewarding Putin's aggression would embolden him to launch further forays into former Soviet territory, upending the post-Cold War landscape of the entire continent. Other scholars have suggested it might betaken as a signal in Beijingthat it's own designs on Taiwan may escape unpunished. The fact that Trump agreed to the summit in the first place, without any change in Russia's behavior or position, reinforced fears in Ukraine and Europe that Trump and his envoy, Steve Witkoff, are misreading Putin and have yet to formulate a coherent strategy on how to end the conflict, experts said. There is a fear in Germany and other European countries that the U.S. president could agree to "a ceasefire at any price," Forstner said. Though Trump has in recent weeks expressed verbal frustration with Putin, he has done little to punish him in practical terms. A supposeddeadline last Friday for Putin to agree to the war or face punishing tariffswas postponed after the summit was announced. In reality, Putin has not shifted his stance since December 2021 when he issued to Western countries a set of eight demands, including a promise that Ukraine would never join NATO and an agreement to the alliance's military forces from Russia's eastern flank. If anything, emboldened by a war he believes he is winning, Putin has only doubled down, now insisting on a larger landgrab in Ukraine and its effective surrender. Many Ukrainians say their best case scenario is that the talks don't produce much at all. But the symbolism of the meeting still stings. "It's just simply an unpleasant fact that it is happening," said Andrusyak, the communications analyst in Kyiv, "and that it is happening kind of behind our backs."
