The OP I’m pretty sure is being sarcastic and referring to this obnoxious book by Francis Fukuyama: https://en.m.wikipedia.org/wiki/End_of_history

He had this absurd premise that because the Soviet Union collapsed and free trade was surging every place everywhere would coalesce to a boring democracy.

there is a lot of fear mongering about nuclear holocaust wrt NATO joining the war etc., but this is incredibly far fetched even in a worst case scenario[1]. I don't say the nuclear threat is nil, but it's also not as bad as war-hawks pondering escalation scenarios or the media makes it out to be.

What do you think would happen to Putins daughters in London, to the family members of oligarchs, to anyone who carries the smell (shame) of a past support of that regime. Even enemies of the West will think twice and have no choice supporting the force that is stronger. (whether that's good or bad or if they like it or not)

anyway nobody knows anything about any of this even the ones who are supposed to be experts in it. so certainly don't take my word for it but do question it when they make it clean cut.

[1] assume RU does launch nukes without sabotage on their systems before, and 1 or 2 cities will be lost to nuclear holocaust. There will be immediate containment of many of the missiles not fulfilling their objective. This is a lot messier than the academic idea of a neat escalation scenario that ends in total annihilation of the human race including a nuclear winter.
