Motherfucker I asked you how this bum ass fuckin country was founded, it was founded on fuckin bloodlust, they operate on fuckin bloodlust, and for some fuckin reason you act like it's so confusing that they've earned this hate. You must be a dipshit
America has killed millions, funded terrorism around the world, overturned governments and replaced them with fascists to open countries up to exploitation resulting in the absolute most horrible conditions imaginable.
Meanwhile all you know about these other countries is what America's ruling class feeds you- that they are evil, backwards nations incapable of governing themselves.
Unfortunately this is also racist - you probably didn't want to hear that but hey you're the one who thinks these things. It's also pretty racist that America itself was founded on the genocide of millions of real Americans (Natives). It's not looking good for you.
Anyway, this is all sort of long and history may be sort of boring to you. But the conclusion to all of this is that you just aren't very smart.
