I don't mean to pick on you in particular, but the popular narrative pretty severely misunderstands what was so controversial about pre-WWII appeasement. The problem isn't that Chamberlain tried to avoid going to war or applied insufficient sanctions to prevent Hitler from conquering the Sudetenland - he approved of it, personally flying to Germany to give him permission, and then talking afterwards about how Hitler's a peace loving guy who'll never invade anyone again. He didn't even wait for Hitler declare the war first! It's very dissimilar to the current scenario, where everyone involved agrees that Putin isn't peace loving and has no legitimate grievances.

More flippantly, I think there are some serious questions to ask yourself if you find yourself staking out a more pro-war position than architects of the Iraq War, none of whom think NATO should send in troops here.
