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.
It'll be like conservatives with Vietnam: a stab in the back narrative (albeit less visceral due to it being a proxy war.)
Yep, "they didn't let us win" cope.
we gotta start making flowcharts for the different stages of manipulative rhetoric they use as an issue progresses from background to forefront to background again
