U.S. Orders Nuclear Testing to Resume After Russia Hails Poseidon Trial

Overview

• President Vladimir Putin said Russia successfully activated the nuclear propulsion of its Poseidon underwater drone and claimed it cannot be intercepted.
• President Donald Trump ordered an immediate resumption of U.S. nuclear testing and posted the directive on Truth Social, noting the last U.S. explosive test occurred in 1992.
• The Pentagon said it will announce the technical scope and timing later, leaving unclear whether the United States will conduct explosive detonations or non-explosive activities.
• The CTBTO warned that any explosive nuclear test would be harmful and destabilizing and said its global monitoring system stands ready to detect such events.
• The Kremlin denied restarting explosive tests and said Russia would respond if Washington ends the moratorium, while China urged the United States to respect the comprehensive test-ban.
