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.
The libs will still be anti-Russian in general, but the state and the media will definitely pull a 180 when Ukrainian neo-nazis begin their campaigns of violence across Europe, the libs will then pretend they never normalized global neo-nazism and decry Ukrainians in the same strident tone they currently decry Russians
The blowback from this war will be hideous and the libs are going to be extremely obnoxious about it the whole time, I suspect by 2025 the libs will all become Polish nationalists and start accusing the "tankies" of being neo-Nazis apologists for opposing the deportation and liquidation of every Ukrainian refugee for the actions of Nazis that libs armed, that's the level of absurdity I'm expecting
Get ready for the whiplash
This is spiritually true
We'll also see many people justify the neo-Nazis, by saying they're necessary to weed out communists and get rid of immigrants in Europe.
Libs will probably be both defending the nazis and also denouncing them, depending what makes them look good in that moment.
I think this bit would heavily depend on the lib lol. I guess I can see a case where as the refugee crisis worsens more and more libs become more openly anti-refugee (scratch a liberal ect) but the ones I'm generally talking about in these threads are the "refugees are welcome" type of lib.
"weed out communists" also depends on the level of ideological commitedness probably.
