That's bullshit. The author of that little brain fart must not have noticed that we haven't used nerve gas on our own people, we haven't aligned ourselves with terrorists, and we didn't celebrate the killing of innocent people in the WTC attacks.
America and Americans are not perfect. No one is. We try, though; sometimes we try harder than others. Right now we're trying to do somthing right. No one likes war, but if it makes the world a safer place, so be it.
