But I'd point out that America has A LOT of blood on its hands. A half million Iraqi's being the most recent, Vietnamese before that, and Koreans before that. Still going strong with drone strikes. Banana republics in central America, mucked around in south America. Proxy wars in Africa. Keeping the Middle East destabilized. The average American seems to support all of the above, which just means it will continue.
I don't want to say that America is an evil country, but it is the biggest and violates the rights of a lot of people (to say the least) in pursuit of its interests. It's an empire warping the world to its desires. Economically (as you mentioned), culturally, and militarily. That's what big powerful countries do.
