I think a material difference between Iraq (v2 anyway) and Ukraine is that they can keep doing the "well Russia was the aggressor" thing indefinitely even if the reality is more complicated.
also yes obviously some libs are still stubborn about Iraq, the worst ones, but for the most part its generally agreed that the Iraq War was a bad thing.
Again ?????????? What the fuck does this even mean?
The western powers put ex nazis in control in West Germany but I dont think thats what you're asking about.
