President Biden has warned the world faces the threat of “Armageddon” if Russian President Vladimir Putin decides to use a nuclear weapon in Ukraine. Biden was speaking at a Thursday evening fundraiser for the Democratic Senatorial Campaign Committee at the home of James Murdoch, son of media mogul Rupert Murdoch. In widely quoted remarks, Biden said, “For the first time since the Cuban missile crisis, we have a direct threat of the use of nuclear weapons if in fact things continue down the path they are going. … [Putin is] not joking when he talks about potential use of tactical nuclear weapons or biological or chemical weapons because his military is, you might say, significantly underperforming.”
