President Donald Trump’s pursuit of an end to the war between Russia and Ukraine is increasingly being driven by his own impatience — with Ukrainian President Volodymyr Zelenskyy and European leaders who Trump believes are standing in the way of both peace and future economic cooperation between Washington and Moscow.

Trump, who has called for Russia’s return to the G7 and spoken repeatedly about his eagerness to bring Russia back into the economic fold, laid bare his frustrations Monday at the White House with POLITICO’s Dasha Burns for a special episode of “The Conversation.” He derided European leaders as talkers who “don’t produce” and declared that Zelenskyy has “to play ball” given that, in his view, “Russia has the upper hand.”

Zelenskyy, who Trump grumbled hadn’t read the latest peace proposal, spent Monday working with the leaders of France, Germany and Britain on a revision of the Americans’ 28-point proposal that he said has been shaved down to 20 points.

“We took out openly anti-Ukrainian points,” Zelenskyy told a group of reporters in Kyiv, emphasizing that Ukraine still needs stronger security guarantees and that he isn’t ready to give Russia more land in the Donbas than its military currently holds.

With Russia unlikely to budge from its demands, the White House-driven peace talks appear stalled. And as Trump’s irritation deepens, pressure is mounting on the Europeans backing Zelenskyy to prove Trump wrong.

“He says we don’t produce, and I hate to say it, but there’s been some truth to that,” said a European official, one of three interviewed for this report who were granted anonymity because they were not authorized to speak publicly. “We are doing it now, but we have been slow to realize we are the solution to our problem.”

The official pointed to NATO’s increased defense spending commitments and the PURL initiative, through which NATO allies are buying U.S. weapons to send to Ukraine, as evidence that things have started to shift. But in the near term, the European Union is struggling to convince Belgium to support a nearly $200 billion loan to Ukraine funded with seized Russian assets.

“If we fail on this one, we’re in trouble,” said a second European official.

Trump’s mounting pressure on Ukraine makes clear that months of careful management of the president through private texts, public flattery and general deference has gotten Europe very little.

But Liana Fix, a senior fellow for Europe at the Council on Foreign Relations, said that the leaders on the other side of the Atlantic “know very well that they can’t just stand up to Trump and tell him courageously that, you know, this is not how you treat Europe, because [of] the existential dependence that is still there between Europe and the United States.”

Still, some in Europe continue to express shock and revulsion over Trump’s lopsided diplomacy in favor of Russia, disputing the president’s assessment during his POLITICO interview that Putin’s army has the upper hand despite its slow advance across the Donbas, more than half of which is now in Russian control.

“Our view is not that Ukraine is losing. If Russia was so powerful they would have been able to finish the war within 24 hours,” a third European diplomat said. “If you think that Russia is winning, what does that mean — you give them everything? That’s not a sustainable peace. You’ll reward the Russians for their aggression and they will look for more – not only in Ukraine but also in Europe.”

Trump has refused to approve additional defense aid to Ukraine, while blasting his predecessor for sending billions in aid — approved by Democrats and many Republicans in Congress — to help the country defend itself following Russia’s Feb. 2022 invasion.

Jake Sullivan, President Joe Biden’s national security adviser, said Trump’s brief that Russia is prevailing on the battlefield doesn’t match the reality.

“Russia has not achieved its strategic objectives in Ukraine. It has completely failed in its initial objective to take Kyiv and subjugate the country, and it has even failed in its more limited objective in taking all of the Donbas and neutering Ukraine from a security perspective,” Sullivan said, adding that he thinks Ukraine could prevail militarily with stronger U.S. support.

“But if the United States throws Ukraine under the bus and essentially takes Russia’s side functionally, then things, of course, are much more difficult for Ukraine, and that seems to be the direction of travel this administration is taking.”

The White House did not respond to a request for additional comment.

Clearly eager to normalize relations with Moscow, Trump appears to be motivated more by the prospect of cutting deals with Putin than maintaining a transatlantic alliance built on shared democratic principles.

Fiona Hill, a Russia expert who served on Trump’s national security council in his first term, noted that the U.S.-Russia diplomacy involves three people with business backgrounds and investment portfolios: special envoy Steve Witkoff and Trump son-in-law Jared Kushner on the U.S. side and Russia’s Kirill Dmitriev, the head of Russia’s sovereign investment fund.

“Putin’s always thinking about what’s the angle here? How do I approach somebody? He’s got the number of President Trump,” Hill said Monday on a Brookings Institution podcast. “He knows he wants to make a deal, and he’s emphasizing this, and all the context is business, not really as diplomacy.”

Additionally, Trump is eager to end Europe’s decades-long dependence on the U.S., which he believes has been saddled with the burden of its continental security for far too long.

Ending the war with a deal that largely favors Putin would not only burnish Trump’s own self-conception as a global peacemaker — it would serve final notice to Europe that many of America’s oldest and most steadfast allies are truly on their own.

Trump’s new national security strategy, released last week, made that point explicit, devoting more words to the threat of Europe’s civilizational decline — castigating the entire continent over its immigration and economic policies — than to threats posed by China, Russia or North Korea.

Asked by POLITICO if European countries would continue to be U.S. allies, Trump demurred: “It depends,” he said, harshly criticizing immigration policies. “They want to be politically correct, and it makes them weak.”

Europe, despite years of warnings from Trump and their own growing awareness about the need for what French President Emanuel Macron has called “strategic autonomy,” has been slow to mobilize its defenses to be able to defend the continent — and Ukraine — on its own.

At Trump’s behest, NATO members agreed in June to increase defense spending to 5 percent of GDP over the coming decade. And NATO is now purchasing U.S. weapons to send to Ukraine through a new NATO initiative. But it may be too little, too late as the war grinds into a fourth winter with Ukraine’s military low on ammunition, weapons and morale.

“That is why they will continue to engage this administration despite the strategy,” Fix said.

And while Trump sees Ukraine and European stubbornness as the primary impediment to peace, many longtime diplomats believe that it’s his own unwillingness to ratchet up pressure on Moscow — Trump imposed new sanctions on Russian oil last month, only to pull some of them back — that is rendering his peacemaking efforts so fruitless.

“It’s not enough to want peace. You’ve got to create a context in which the protagonists are willing to compromise either enthusiastically or reluctantly,” said Richard Haass, the former president of the Council on Foreign Relations who served as a senior adviser to Secretary of State Colin Powell in the George W. Bush administration. “The president has totally failed to do that, so it’s not a question of wordsmithing. In order to succeed at the table, you have to succeed away from the table. And they have failed to do that.”
