Donald Trump’s remarks on Ukraine on Monday were far from the biggest announcement the US president could have made.

By Lili Bayer and Andrew Gray BRUSSELS (Reuters) -Several European countries said on Tuesday they were willing to buy U.S. arms for Ukraine under a scheme announced by U.S. President Donald Trump, although arrangements still needed to be worked out.

American fatigue with the war and the fickleness of the Trump administration remain concerns for Ukraine’s leaders.

His announcement on Monday that he would send “top of the line” weapons to Ukraine and slap Russia with “severe” sanctions if it doesn’t agree to a ceasefire within 50 days marks a turnabout, especially for a man who only months earlier had bullied Ukrainian President Volodymyr Zelensky in the Oval Office.

Trump asked Volodymyr Zelenskyy whether Ukraine could strike Moscow, an inquiry that the White House says was merely a question but one that came hours after he voiced frustration at Putin’s refusal to accept a ceasefire.

President Trump has effectively handed Vladimir Putin an extraordinary green light: 50 days to finish off his brutal summer offensive in Ukraine before facing any consequences.

President Donald Trump will meet with NATO Secretary-General Mark Rutte to announce plans to sell weaponry that they can then pass to Ukraine for its war with Russia.

Under the plan, other NATO countries would buy U.S.-made arms, then give them to Ukraine to defend itself against Russia. NATO’s secretary general was set to meet Mr. Trump on Monday.
