The nuclear clock just reset. Minutes before his meeting with Xi Jinping, Donald Trump stunned the world by ordering the U.S. military to “immediately begin” nuclear weapon testing — ending a 33-year moratorium. The Kremlin, caught off guard, responded cautiously but warned, “If someone departs from the moratorium, we will act accordingly.” Moscow clarified that its recent Burevestnik and Poseidon tests were not nuclear detonations. As global powers brace for escalation, fears of a new nuclear arms race are rapidly mounting across Washington, Moscow, and Beijing.
