Nuclear 'Armageddon' threat back for 1st time since Cold War —Biden

US President Joe Biden said Thursday the world risks nuclear "Armageddon" for the first time since the Cold War and that he is trying to find Russian President Vladimir Putin's "off-ramp."

"We have not faced the prospect of Armageddon since Kennedy and the Cuban missile crisis" in 1962, Biden said at a Democratic party fundraising event in New York.

Putin is "not joking" when he threatens to use nuclear weapons, and "we are trying to figure out what is Putin's off-ramp. Where does he find a way out?" —Agence France-Presse
