So with that in mind, anything Putin says that implies the UK, EU or USA are a nuclear target is nothing but sabre rattling. It's simply not going to happen before a severe battlefield escalation and a severe deterioration in geopolitical relations, even considering how bad they already are.

And if Putin were to press the button, it would be the last act of a madman. He knows it's suicide. He could just put a gun to his head and save humanity the horror. It at least goes through a man's mind before he nukes a major city, right? You think "do I really want to leave this legacy?".

Full scale global nuclear war doesn't really worry me, even in this geopolitical climate. Nobody wins, and everybody knows it. More chance that madman in Korea uses a strategic nuke, and even that is a near zero probability.

idk if anyone is mad enough to use a tactical nuke. If and when it happens it's a new world we're living in, that much is for sure.
