"A Nuclear Bluff is just that, a Bluff. Putin can't win in a nuclear war and if he uses nukes anywhere, he is done for."

We don't know what he would do. A desperate dictator might just use nukes.

There's also the greatly increased risk of accidentally starting a nuclear war -- something we've come close to multiple times, even in peace time. In war time that's just short of WW3, the risk is increased exponentially.

No sane person wants to gamble with the literal fate of the world. Yet both sides are doing this by getting this close to WW3... that doesn't lend confidence to the possibility of staying out of a nuclear war if NATO "calls Putin's nuclear bluff".
