No one can win a war by first use of a nuclear weapon.
People who think so are wrong. Nuclear weapon use, even one, will lead to that—and every major power’s-death and destruction.
Putin isn’t stupid. If you admire him, you should know that.
Well, that seems obviously incorrect.
Putin is intimidating the West so we won't send Ukraine all the weapons they need.
People who think they can survive their own "first use" of nuclear weapons may be "wrong" - but can you guarantee that they know it? Or even care? It's more than a little entertaining to see westerners insisting they can predict the actions of foreign religious and political extremists; people who believe they can make such predictions, with consistent reliability, are also "wrong".
Personally, I think it is highly likely that nuclear weapons will be used again. It might happen in a way that average Americans do not expect, that might provide some measure of "plausible deniability" - picture a small freighter entering a port somewhere, and disappearing (along with the port city) in a mushroom cloud. Somebody would be blamed, but it might well be that country's enemy de jour, rather than the actual perpetrator...

I think that happened once already
