Not hundreds of thousands but millions went on the streets in major European streets. The invasion on Iraq was as bad as invasion on Ukraine, and it doesn't matter that Saddam was a cruel dictator killing his own people. There is absolutely no justification for that.
And history shows we were right: starting a war in Middle East doesn't bring peace but only more wars, and sometimes even evil we hadn't imagined like the ISIS. And I'm happy Americans finally left both countries, and they finally learned the hard lesson that this kind of aggression has only negative consequences.
I was just pointing out that if you know somebody who was pro invading Afghanistan (which in 2001 was like, 90%, so most people do) or Iraq you know somebody who would probably be pro-Ukraine war were they born Russian. It shouldnt be a mystery.
Your bubble likes to downplay stuff like the odessa trade unions massacre.
It puzzles me that you find it puzzling. How hard was it to talk Americans into waging a war of aggrrssion on Iraq or Afghanistan? Not very.
