US nuclear testing resumption could harm alliances

President Trump indicated the U.S. would resume nuclear testing due to other nations' programs, causing ambiguity and opposition from the Energy Secretary. The statement suggests testing delivery systems or low-yield components, not warheads. This follows claims of "supercritical" tests by China and Russia, which are difficult to detect. Resuming full-scale tests would violate the Comprehensive Nuclear-Test-Ban Treaty, alienate allies, and potentially undermine U.S. alliances and deterrence capabilities.
