President Vladimir Putin said on Tuesday that Russia successfully tested the Poseidon unmanned nuclear-powered underwater vehicle, confirming for the first time that its onboard nuclear reactor had been activated during launch. The announcement sparked alarm across NATO, with Belgium’s Defence Minister Theo Francken warning that any Russian strike on Brussels would be viewed as an attack on “the heart of NATO.” Former Russian President Dmitry Medvedev responded online, mocking Francken and warning that “Belgium will disappear” if used as a test ground. The exchange marks one of the sharpest rhetorical escalations between Moscow and a European NATO member since the start of the Ukraine conflict, as Western officials warn of growing risks from Russia’s new generation of autonomous nuclear systems.
