What serious global power hasn't done awful things? Morality is a social construct and continually evolving. I'm not sure what you would want me to do that you would not consider 'brushing aside' - I certainly think many US actions have been horrendous. My comparison is what the situation would have been if there was another superpower (e.g. the Soviet Union post WWII or China now) or no superpower and I think the world would be less prosperous and more violent. Indeed, there is no way to appoint someone to be the global police officer, the U.S. took that upon themselves sometimes to the benefit, sometimes the detriment of the rest of the world and itself (as you can see by just how much pushback there is on both the right and the left in America about America's role in the world). I just don't agree that it's been net negative.
