PARIS >> President Donald Trump on Friday said negotiations between Ukraine and Russia are “coming to a head” and insisted that neither side is “playing” him in his push to end the grinding war.

Trump spoke shortly after Secretary of State Marco Rubio warned that the U.S. may “move on” from trying to secure a Russia-Ukraine peace deal if there is no progress in the coming days, after months of efforts have failed to bring an end to the fighting.

“Now, if for some reason, one of the two parties makes it very difficult, we’re just going to say you’re foolish. You are fools, you horrible people,” Trump said. “And we’re going to just take a pass. But hopefully, we won’t have to do that.”

Rubio’s dour assessment came after landmark talks in Paris among U.S., Ukrainian and European officials produced outlines for steps toward peace and appeared to make some long-awaited progress. Another meeting is expected next week in London, and Rubio suggested it could be decisive in determining whether the Trump administration continues its involvement.

“We are now reaching a point where we need to decide whether this is even possible or not,” Rubio told reporters in Paris. “Because if it’s not, then I think we’re just going to move on. It’s not our war. We have other priorities to focus on.”

He said the U.S. administration wants to decide “in a matter of days.”

The State Department said Rubio issued the same warning in a phone call Friday with NATO Secretary-General Mark Rutte, telling him that “if a clear path to peace does not emerge soon, the United States will step back from efforts to broker peace.”

Trump said “Marco is right” that the dynamic of the negotiations must change, but stopped short of saying he’s ready to walk away.

“Well, I don’t want to say that,” Trump said. “But we want to see it end.”

Rubio’s comments stepped up pressure on both sides to reach a peace deal, even as the U.S. and Ukraine made progress on a minerals agreement that Trump has sought to recoup billions of dollars in military assistance that Washington has sent Kyiv since Russia’s full scale invasion in February 2022.

They also indicated the road to a complete truce will be long and mired with contention, despite Trump repeatedly claiming on the campaign trail that he could end the war within a day. Trump said last month that he was “being a little bit sarcastic.”

Coming out of the Paris talks, the Americans are ready to use both carrot and stick strategies with Russia and understand the need for ?a relationship of force that allows them to get commitments from both sides,” said a French diplomatic official who took part in the talks but was not authorized to comment publicly.

The Americans and Europeans discussed sanctions but “not the question of easing sanctions” on Russia. The official said the European Union needs to use “all instruments at our disposition,” notably to have levers of influence over the Russians to ensure they commit to eventual promises.

U.S. Vice President JD Vance struck a more hopeful tone in Rome on Friday, ahead of talks with Italian Prime Minister Giorgia Meloni.

“We think we have some interesting things to report on, of course in private,” he said. On the negotiations, “I won’t prejudge them, but we do feel optimistic that we can hopefully bring this war, this very brutal war, to a close.”

He didn’t give more details.

The U.S. and Ukraine are nearing a long-delayed deal granting the U.S. access to Ukraine’s vast mineral resources, which has been intertwined with Trump’s peace push. Trump said Thursday: “We have a minerals deal.” Ukraine’s economy minister said Friday that the two countries signed a memorandum of intent ahead of a possible fuller agreement later.

The deal, which Ukrainian Economy Minister Yuliia Svyrydenko said she signed with U.S. Treasury Secretary Scott Bessent, is expected to pave the way for significant investments, infrastructure modernization and long-term cooperation.
