United States President Donald Trump told his Ukrainian counterpart Volodymyr Zelensky on Friday that he is “gambling with World War III” amid ongoing negotiations over the conflict. Addressing Zelensky in front of reporters in the Oval Office, the American head of state warned him to be thankful for the US support. “You either make the deal or we are out,” Trump stressed, calling the Ukrainian president’s comments disrespectful. The exchange between the two leaders quickly became heated, with Vice President JD Vance stepping in to intervene.
