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.
Look at the situation with Ukraine - Ukrainians and Russians are as close to brothers as you can get, but for some reason the Ukrainians are white europeans while the Russians are slavic orcs, asiatic, etc. All this will take is pulling that honorary aryan designation back from the Ukrainians and what do you know, they were asian slavic orcs the whole time
