Trump Orders Immediate Resumption of U.S. Nuclear Testing Before Xi Summit in Busan

The directive, issued without test specifics, ends a three-decade U.S. pause as arms-control limits near expiration.

Overview

  • Trump announced on Truth Social that he directed the Defense Department to begin nuclear-weapon testing "on equal basis," without specifying what types of tests or systems would be involved.
  • The declaration came minutes before his meeting with China’s Xi Jinping in Busan, a timing framed by recent Russian weapons trials and intended as a strategic signal.
  • After the meeting, Trump and Xi touted narrow trade steps: China will suspend some rare-earth export controls for one year and resume large U.S. soybean purchases, while the U.S. trims Fentanyl-related tariffs to 47%.
  • Immediate pushback surfaced in Congress, with Nevada Democrat Dina Titus vowing legislation to block testing, as analysts warned of erosion of non-proliferation norms with New START set to lapse in February 2026.
  • Regional tensions also flared as North Korea reported sea-to-sea cruise-missile tests ahead of Trump’s trip, adding to a spate of military demonstrations cited in the U.S. justification.
