I agree with the general consensus that this song is about the fear the world has of America, and the mindless following of popular, true-blue American culture by its people. (Not to say, of course, that other countries don't have mindless followers of their own culture, but that's another story.) In addition, when I heard the "God is an American" part, I saw it as David Bowie mocking the American assumption that God is just a typical American. Perhaps he is stating it over and over to impress the listener with how absurd a statement it really is. I could see it being other ways, but that's what it meant to me.
