I can’t tell you exactly why Trump chose to repeat these falsehoods, or why his director of national intelligence, Tulsi Gabbard, once made a TikTok video of herself repeating them, or why they directly echo the Russian propaganda that has long sought to portray Zelensky, along with the nation of Ukraine itself, as illegitimate. Plenty of Republicans, including some I met in Munich, know that these claims aren’t true. American allies must draw a lesson: Trump is demonstrating that he can and will align himself with whomever he wants—Vladimir Putin, Mohammed bin Salman, perhaps eventually with Xi Jinping—in defiance of past treaties and agreements. In order to bully Ukraine into signing unfavorable deals, he is even willing to distort reality.
