Gurgen I didn't call opposition to ongoing war appeasement, I called giving away land for peace appeasement. That's simply what it is. You never gave me that example where this worked. It hasn't worked in 200,000 years of human history and never will;
What does "worked" mean? If you mean stopped expansionist imperialism, fine. You could argue it hasn't worked in that sense. But ceding territory to an enemy after losing in combat has, historically, marked the end of just about every discrete war in human history. This means the end of combat operations, shelling, destruction of heritage and infrastructure, and the mass killing, torture, and rape of civilians and military personnel alike. These are more important goals than maintaining ephemeral political boundaries or labels on maps.
If you cannot secure the military, financial or political capacity to deter an invasion, it's likely you've already lost. Playing out the war is so archaic at this point in human history. If NATO wanted to, they would have matched and exceeded Russian military presence on the Ukrainian borders. They didn't. They wanted a drawn-out conflict for their war-mongering corporate benefactors and Ukrainian leadership played their part perfectly.
The losers are the dead, the wounded, the tortured and disenfranchised - they are resistance fighters who have been lied to, children whose futures are stolen, and families torn apart. Ukraine isn't worth all that, because a nation-state is unequivocally not equivalent with its people. Why fight for a bunch of corporate leeches? For arms dealers and energy executives? For venture capitalists and the political elite? Basically, why fight for JD fucking Vance, just so he can insult you on global television? It doesn't make any sense.
