I get that it isn’t popular, but if it ends the war, it’s for the best.
Perhaps you’d like to see another $250 billion spent, 1 million lives lost and another 15 years of war. At what point is it not worth it?
It would end this stage of this war for now, while ensuring more wars will happen and this war will be renewed. Dictators would learn that all they have to do is make some people in the west uncomfortable with conflict and they will get what they want. Appeasement has the track record of simply delaying the issue while making it much worse to resolve in the long run.
