Not that long ago, I was under the impression that americans knew that they were the "bad guys" in all of those wars, but stood quiet, because they gained cheap oil and other benefits from most of them. I also got that sentiment from eg. the french, when their governments did something bad in any of their (former) colonies. There were even movies/documentaries (Michael Moore comes to mind), or even historic conflicts (vietnam and the Hippie culture around it), showing the US doing bad stuff around the world.

And now? It makes me sad, that so many american people actually consider themselves the "good guys" for destroying random countries and killing people there. Like they did nothing bad, when they bombed peoples houses, occupied their countries, stole their oil, etc.
