Trump Orders U.S. Nuclear Tests After Russia Announces Poseidon Trial

Overview

• Vladimir Putin said Russia activated the nuclear propulsion of the Poseidon undersea drone in a successful test and recently trialed the nuclear‑powered Burevestnik cruise missile.
• President Donald Trump posted that he instructed an immediate resumption of U.S. nuclear tests, with the Pentagon saying scope and timing will follow technical consultations.
• The Kremlin warned it would respond if Washington abandons the testing moratorium and stressed that Russia’s recent activities did not involve explosive nuclear detonations.
• China urged U.S. adherence to the Comprehensive Nuclear‑Test‑Ban Treaty, and the CTBTO cautioned that any explosive test would be destabilizing while noting its network can detect such events.
• Experts and U.S. agencies say preparing an underground explosive test would take months to years; the United States last conducted a nuclear detonation in 1992, and Vice President J.D. Vance argued testing ensures arsenal reliability.
