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.
“well even if we were lied to, it was still worth getting rid of Saddam”
I dont hear this very often from libs. Usually they say getting into Iraq at all was a bad idea altogether. But thats just my experience.
