Trump appeared to place the onus of ending the war on the Ukrainian leader and said Ukraine should give up Crimea and its hopes of joining NATO — key Kremlin demands.

As Trump was flying into Alaska, he was threatening severe consequences if Putin didn’t play ball. Trump stressed that he wouldn’t be happy if he left the summit without an immediate ceasefire and that new sanctions may be necessary if the Russians were intransigent.

Mark Rutte, the secretary-general of NATO, briefly addressed Trump and European leaders at the White House. “Let’s make the best out of today,” he said with a note of cheer. He repeatedly thanked Trump for his attention to the conflict.

Donald Trump has told Ukraine to give up hopes of getting back annexed Crimea or joining NATO as he prepares to host President Volodymyr Zelensky and European leaders in Washington on Monday to press Kyiv into accepting a peace deal with Russia.
