Putin issues warning to US with new nuclear doctrine

Russian President Vladimir Putin on Tuesday approved an updated nuclear doctrine, saying that Russia could consider using nuclear weapons if it was subject to a conventional missile assault on it supported by a nuclear power. The decision to change Russia's official nuclear doctrine is the Kremlin's answer to a reported decision by the administration of U.S. President Joe Biden to allow Ukraine to fire American long-range missiles deep into Russia. The updated doctrine, which outlines the threats which would make Russia's leadership consider a nuclear strike, said an attack with conventional missiles, drones or other aircraft could be considered to meet these criteria.
