Why do we stop at the last 60 years? Why don't we dig up the civilians that the Caliphates and Ottomans had to kill while they had to police the center of the known world back then. Percentage wise, they did a very impressive job especially considering the lack of modern implements. The wholesale liquidation of Armenians by Ottoman for example, something Hiter tried to model himself after. At least the US policing of the world hasn't used policies of explicit up-close-personal genocide one and a time.
