Biden believes nuclear threat is this high for the first time since the Cuban Missile Crisis

US President Joe Biden said this at a press briefing.

We have a guy that I know pretty well. He is not joking when he talks about the potential use of tactical nuclear, biological or chemical weapons, because his military forces can be said to be far behind, — he said.

The world has not faced the prospect of Armageddon since the Caribbean Missile Crisis, he said, but for the first time since that time, the threat of the use of nuclear weapons has arisen.

So far, the US is trying to figure out what Putin will do next.
