U.S. President Donald Trump and Ukrainian President Volodymyr Zelensky had a tense showdown in the Oval Office on Friday—the likes of which many world leaders were able to watch unfold, thanks to the media being present with their cameras rolling. The pair, joined by U.S. Vice President J.D. Vance, interrupted each other repeatedly during a meeting initially intended to be about a key U.S.-Ukraine minerals agreement.

“You don’t have the cards right now,” Trump told Zelensky in the exchange, referencing Ukraine’s ongoing war with Russia and Russian President Vladimir Putin. Zelensky responded with a point of his own: “We’re not playing cards.”

Trump made various other remarks about Zelensky and Ukraine’s current position, and the involvement the Biden Administration had in supplying support and funds to Ukraine after it was invaded by Russia. Zelensky remained steadfast on his point that a cease-fire agreement between Ukraine and Russia wouldn't be sufficient without security guarantees from the U.S., and that Putin cannot be trusted.

“You’re gambling with [the] lives of millions of people, you’re gambling with World War III and what you’re doing is very disrespectful to this country,” Trump told Zelensky.

Trump followed that up by saying: “Your men are brave, but they had our military. If you didn’t have our military equipment, this war would have been over in two weeks.”

Shortly after the exchange, Trump canceled a planned press conference with Zelensky and cut off negotiations. He took to his own social media platform, Truth Social, where he wrote that Zelensky “is not ready for Peace if America is involved.”

“He disrespected the United States of America in its cherished Oval Office. He can come back when he is ready for Peace,” Trump said.

Following the Oval Office confrontation, many world leaders have spoken out, remarking upon what happened.

Many have reified their support for Ukraine in its defense against Russia’s invasion. A few have supported Trump. Zelensky took to posting on X (formerly Twitter) to thank the world leaders who have come to his defense on the platform.

The Ukrainian leader travelled to London and met with British Prime Minister Keir Starmer, as planned, on Saturday. Zelensky remarked on social media that they'd had a "meaningful and warm meeting."

"During our talks, we discussed the challenges facing Ukraine and all of Europe, coordination with partners, concrete steps to strengthen Ukraine’s position, and ending the war with a just peace, along with robust security guarantees," Zelensky said.

Later on Saturday, British Chancellor of the Exchequer Rachel Reeves and Ukraine's Finance Minister Sergii Marchenko signed the U.K.-Ukraine Bilateral agreement. The U.K. reinforced its support for Ukraine with a £2.26 billion ($2.84 billion) loan to bolster Ukrainian defence capabilities.
