Is ending the war in Ukraine as fast as possible (i.e. by handing Russia control over it) a desirable outcome when we KNOW due to multiple historical precedents, public declarations, and even stated intent from Putin himself, that Russia will immediately move to invade other countries like Belarus, Kazakhstan, Moldavia, Georgia, etc?
Of course it fucking isn't. Russia backing the fuck down and learning to respect national sovereignty is the entire point of this war.

Also, ignoring the geopolitics (which is a stupid enough sentence by itself...), who the fuck are you to tell the Ukrainians what they should or should not be doing? They want to fight Russia, they don't want sheltered western bois telling them to surrender to the oppressor who will genocide them, again.

Your line of thinking is wrong. It's patronizing, it's belittling, it's cowardly, it's unproductive, and it's DANGEROUS. It's how we got the Munich treaty, the Vichy Regime, and Collaboration. So we fight Imperialism, wherever we see it. We fight the Nazis when they invade our country, we dunk on the US when they commit imperialism in the ME, and we militarily enable our allies to drive Russia out of their sovereign territory.
