U.S. President Donald Trump has directed the Pentagon to begin matching other nuclear powers in weapons testing, citing recent activity by Russia and China. In a post on Truth Social, Trump wrote: “Because of other countries’ testing programs, I have instructed the Department of War to start testing our nuclear weapons on an equal basis. That process will begin immediately.” The announcement came less than an hour before Trump’s meeting with Chinese President Xi Jinping in South Korea on Thursday — their first face-to-face talks since 2019 — aimed at easing trade tensions between the two nations.
