The world in the 21st century is not one in which individual sovereign countries are beholden to the dictates of great powers and where therefore a simplified framework for understanding global politics that only considers great powers is useful.

Ukraine fought off the initial Russian attack without US and NATO, do you think they would stop fighting now if support were withdrawn? How exactly do you think the US and NATO could force Ukraine and Russia to the table? Do you think that eastern European countries would withdraw support from Ukraine even absent the US and NATO when Russian incursions on neighbouring territory represent very real threats to them? The entire premise that the US can end this war feels like a hopelessly naive relic of a different era.

My own point of view is that the only way this will end peacefully is with the full withdraw of Russian forces from Ukrainian territory. The question of how this can be achieved without Russia becoming destabilized and fracturing, which I don't feel is desirable, is certainly a concern, although I fear that that may be the only thing that leads to their withdraw. (See Timothy Snyder's piece on the subject: How does the Russo-Ukrainian War end? [1])

If this were a war between NATO and Russia, all those bases that Russian missiles are coming from would be gone. So would Russia's air force. And then the ground-attack planes would start in on all the Russian troops in Ukraine. And they'd feel free to go after every mass of troops that Russia brought anywhere near the border.

None of that is happening. That's how you know it's not a war between NATO and Russia.

To your larger point: You think Russia has the power to destroy the world, so we should let them have their way with Ukraine. You're like a business owner who doesn't interfere when the street gang rapes people outside, because they might burn your business if you did. Can't you see how morally bankrupt that is?
