Relations between Donald Trump and Volodymyr Zelensky have fallen to their lowest point since their heated clash at the White House. Trump has been conceding more and more ground to Moscow as he pushes to end the war. Zelensky has stopped holding back and now answers the American president openly. Their latest mutual callouts show how far the two men's positions have drifted apart. Kyiv worries that Washington may pressure Ukraine into terms written by the Kremlin. Trump, for his part, keeps stressing that he wants the fighting settled quickly. The public quarrel leaves the future of American support for Ukraine hanging in uncertainty.
