Then just don't put them on death ground. If they have a way out, with loss of prestige and resources, but still staying in power, they will take it. India and Pakistan have had border clashes when both countries already had nukes. It was close and very dangerous, but it is still a counter-example to claim that every war between nuclear nations is just automatically bound to become a nuclear war.
All that said, I do in fact support giving Ukraine what it needs in order to defend itself. I think that is in fact a worthy and noble goal.
My mistake, but it was not intended rhetorically.
And, you know, I've never over-reacted or misinterpreted someone. Never. Um... at least not today... um, well, uh...
I also was a bit hair-trigger in my reply to you. In particular, you gave pphysch more grace (the first time) than I gave you.
I do need to remind myself to slow down and check both GP and parent before responding (which is what I didn't do here), so it's all good, really.
Oh, I wouldn't go that far. In fact, I think you could occupy as much as 80% of Russia. As long as you make sure that Putin and his friends were left alive and in charge of the remaining 20%, they wouldn't do a thing.
Nuclear annihilation will not come because of some desperate last ditch effort, but because of some politicians convincing themselves that they not only survive, but win, a nuclear conflict. And it's easier than ever to see that sort of mentality spreading in a world where narrative has become far more important than reality, at least to the idiots and octogenarians in charge.
