Well Sal, I think it is safe to assume that you don't really want an answer that doesn't agree with your own slant, but try this one on.
Civilization has been around for roughly 7,000 years. In that time I don't think you can name a single civiliazation that had an advantage that didn't use it. Be it military, economic, or in some cases cultural. Be it the Assyrians chariot, or the US having the repeating rifle, the stock market, and or Hollywood.
The crimes of the US are many to the indiginious, the african americans, and many other imigrants. But don't think for a second that that isn't universal. The Turks exterminated the Armenians, the Chinese decimated Tibet, the Russians starved the Ukranians. Go ahead, pick any spot in the world. The diference between the US and the the rest of the world is we put our sins on the front page.
Just remember, hypocracy is only possible when you have standards. Yes, occasionally the US has failed to meet them, but more often than not we do very well. We also have stopped genocide one hell of a lot more than we have started it.
