Specifics I like to bring up include-

-The genocide of Native Americans, noting how the desire to expand was a much stronger driving force of the revolution than its claimed

-The American slave trade, “abolition” of slavery, and connecting that to modern times with our prison systems/law enforcement

-Coups around the world! We have so many to pick from, don’t we, but I’m in favor of discussing ‘Banana Republics’ - Honduras is a good one to highlight and has a more recent one to discuss as well. Toppling governments to maintain fruit prices open people’s eyes

-Iraq war, as you said, and how many lies were peddled to get people on board, and the bloodthirsty populace. It ties in nicely to the current ramp up to China

-My personal cherry on top, things like the Tulsa Massacre (1921) and MOVE bombings (1985) to highlight what the American government is willing to do on its own soil to maintain capitalism. The general treatment of groups like the Black Panthers also work

By this point, they should have learned that US history is way bloodier than they were told, all of that shit is lies and mythology, it’ll topple governments on a whim, lie, cheat, manipulate to launch needless wars to maintain power, enslave and opress it’s citizens without qualms, and kill off their own people - or even drop bombs on them - for turning away from capitalism and towards socialism. If that doesn’t make them see things in a different light, then idk what to do
