There isn’t time to name ALL the evil things. Here’s a few goodies though:
project paper clip
Viet Nam (wouldn’t have been evil if we’d actually wanted to win, but we didn’t, and getting into a war you don’t want to win is probably the most evil thing you can do)
at least half a dozen times we inspired people to revolt against their government and doing nothing to back them (again the whole not wanting to win thing)
backing the Shah
backing Marcos
backing Duvalier
we backed a lot of really bad people during the Cold War
And that’s just the 50s, 60s and 70s. We haven’t even gotten into “Iranian Moderates”, abandoning Afghanistan to a decade of chaos after helping kick out Russia, Clinton’s adventure with Haitian dictators, and Obamacare. Our government’s done a lot of evil.
Hey, we allied with Stalin in WWII. We did that to defeat Hitler. Stalin was absolutely as evil as Hitler, but we allied with him to defeat an evil, Nazism, that was more of direct threat to the world. That's what a lot of diplomacy is....taking the best of two bad alternatives. To say we're evil because we ally with some disreputable people from time to time is standing reality on its head. And if we're evil because we, the country, make mistakes, then you're expecting perfection. Humans aren't perfect. They make mistakes. That does not make them evil.
