Appeasement doesn't work. It did not work out for European powers, it did not work for Stalin, and more recently it did not work with Crimea/Ukraine.
Yet every time a portion of the population will wholeheartedly support appeasement policies out of what I can only assume to be a mix of abhorrent cowardice and a pathological compulsion to submit to authority. I can only imagine the kind of fucked-up childhood these people lived, to make them so afraid of fighting back even when they're the ones holding the bigger stick.
