I would imagine there is a similar point of view in many Russians regarding the West (and they can make arguments about abuses and how intrinsically evil the other party is and patriotic jingles and all that too).
So how, on that road, does this end?
I think we know the answer and it really and truly is awful and the end of the world we have previously known.
FYI, they're "dealing with Russia through force" right now. It's just through proxies, and it's going pretty well.
Although there might soon be some "proxies" soon, like Azerbaijan (unfortunately) and (hopefully soon) Georgia.
The road ends the same way it ended last time, 30 years ago - in adjustment of Russian borders.
Unless you claim that a state that can't even manufacture tanks or ordinary cars (or phones; Russia is wholly dependent on technology imports from Europe) is still capable of remanufacturing nuclear warheads, and is willing to sacrifice itself as a state to use them to... not even prove the point, because it would still be a defeat.
Some back and forth, increasing desperate Neocons with no reverse gear pushing the thing. Western society is over indebted and teetering. Eventually the world explodes in fire, billions die, and some version of MAGA presides over a much reduced United States when it ends. (I'd rather believe your prediction but do not).
There might be a way to avoid the scenario (unlikely at this juncture but possible). It isn't with wishful (Russia has lost half it's armed forces) and hostile thinking though.
Just my opinion.
To Ukraine, this is about pretty much everything - Russians are quite open with their intention to erase Ukraine as a nation, and hundred thousand civilians killed in Mariupol alone proves they are serious.
And then there's Russia, USSR's retarded offspring. They will likely get a lifeline, but it's unlikely they will be allowed to keep the army.
