WASHINGTON — President Donald Trump berated Ukrainian President Volodymyr Zelenskyy for being ‘’disrespectful'' Friday in an extraordinary Oval Office meeting, then abruptly called off the signing of a minerals deal with the U.S. that Trump said would have moved Ukraine closer to ending its war with Russia. The astonishing turn of events could scramble international affairs in Europe and around the globe. During his visit with Trump, Zelenskyy had planned to sign the deal allowing the U.S. greater access to Ukraine’s rare earth minerals, then hold a joint news conference. Instead, Ukraine’s leader left the White House shortly after Trump shouted at him, showing open disdain. Untouched salad plates and other lunch items were being packed up outside the Cabinet room, where the lunch between Trump and Zelenskyy and their delegations was supposed to have taken place. The White House said the Ukraine delegation was told to leave. ‘‘You’re gambling with World War III, and what you’re doing is very disrespectful to the country, this country that’s backed you far more than a lot of people say they should have,‘’ Trump told Zelenskky. The last 10 minutes of the nearly 45-minute meeting devolved into a tense back and forth between Trump, Vice President JD Vance and Zelenskyy, who had urged skepticism about Russia’s commitment to diplomacy, citing Moscow’s years of broken commitments on the global stage. Zelenskyy’s main objective going into the sit-down had been to press Trump not to abandon his country and to warn against moving too closely to Russian President Vladimir Putin. Instead he got shouted at while Trump appeared to play up the drama for the cameras. At one point, Zelenskyy said Putin had broken ‘’his own signature'' 25 times on ceasefires and other agreements and could not be trusted. Trump responded that Putin had not broken agreements with him and mostly ducked questions about offering security guarantees to Ukraine, saying he thought the minerals deal — which is now on-hold — would effectively end the fighting.
