Biden warns world would face ‘Armageddon’ if Putin uses a tactical nuclear weapon in Ukraine

In his starkest assessment yet, US president says world is the closest it has come to nuclear catastrophe in sixty years

Biden said on Thursday night: “I don’t think there’s any such thing as the ability to easily (use) a tactical nuclear weapon and not end up with Armageddon.”

US intelligence agencies believe that Putin has come to see defeat in Ukraine as an existential threat to his regime, which he associates with an existential threat to Russia, potentially justifying, according to his worldview, the use of nuclear weapons.
