President Donald Trump is set to make a series of important phone calls on Monday aimed at putting an end to the war in Ukraine. He plans to speak first with Russian President Vladimir Putin at 10 a.m. Eastern Time, followed by a call with Ukrainian President Volodymyr Zelensky, and later with NATO leaders. Trump says the main goal of these talks is to “stop the bloodbath,” referring to the thousands of soldiers dying on both sides every week. He also plans to touch on trade matters during his conversations.

Trump wants to get a ceasefire in place and believes the only way forward is through direct, personal diplomacy. He’s made it clear that if any side stands in the way of a peace deal, they could face sanctions—whether it’s Russia, Ukraine, or even NATO members dragging their feet. If Putin doesn’t show a willingness to negotiate, Trump hinted at the possibility of ramping up sanctions on Moscow.

These calls come just days after Russian and Ukrainian representatives met in Turkey. That meeting led to a prisoner exchange but failed to produce any real breakthrough on ending the fighting. Notably, Putin didn’t attend those talks himself, instead sending lower-level officials, while Zelensky said he wouldn’t show unless Putin did.

Trump sees his role as essential to breaking the current deadlock. He believes that without him personally stepping in, the situation will just continue to spiral. Along with his talks with Putin and Zelensky, Trump will also be coordinating with NATO allies to make sure everyone is on the same page when it comes to the next steps for peace.

In short, Trump is taking the lead on a new diplomatic push to end a war he calls “a war that should have never happened,” and he’s betting that a few tough phone calls can do what years of weak backroom negotiations haven’t.
