Ukrainian President Volodymyr Zelensky joined European and NATO leaders to thank Trump — a lot — six months after the White House accused him of being ungrateful.

New negotiation, new look. When President Volodymyr Zelensky of Ukraine arrived at the White House on Monday to meet with President Trump, he had swapped the military-style clothing that has been his de facto uniform since the war with Russia began in 2022, for a more statesmanlike ensemble: black field jacket, black shirt and black slacks.

It was a striking contrast to the meeting six months ago, when Trump, red-faced and angry, accused an agitated Zelensky of failing to show enough gratitude to the United States. The blowup was so heated that the Ukrainian delegation was sent from the White House without being allowed to eat their waiting lunch.

Volodymyr Zelensky may be unwilling to make political and territorial concessions in his war with Russia, but on Monday, the Ukrainian president made allowances of his own, arriving at the White House in a suit jacket.

President Trump has offered only vague assurances of security guarantees for Ukraine if President Volodymyr Zelensky agrees to cut a deal with Russia.

One detail of President Trump’s meeting Monday with Volodymyr Zelensky drew particular notice: the Ukrainian president’s attire.Zelensky’s decision not to wear a suit at the two leaders’ February meeting in Washington sparked a testy exchange.

Ukrainian President Volodymyr Zelensky said on Tuesday after his meeting with US President Donald Trump and European leaders that security guarantees for Kyiv will likely be worked out within 10 days.

President Donald Trump and others mocked Ukrainian President Volodymyr Zelensky in March when he showed up at the White House in his customary military-style fatigues. Zelensky apparently got the message.
