Trump’s Embrace of Russia Rocks NATO Alliance

BRUSSELS—The argument between President Trump and his Ukrainian counterpart at the White House sent relations between the two countries into a tailspin. It also caused serious damage to an alliance at the heart of the post-World War II order: NATO.

Trump staked out a position that many European allies saw as siding with Russia’s autocratic leader, Vladimir Putin, by dismissing the security concerns of a friendly country in need of Western help. He said Ukrainian President Volodymyr Zelensky was losing the war and had “no cards.”
