You seem to be attacking a straw man for some reason in order to get in digs about President Bush, while completely evading the point - if a poll were possible about Rome while it ruled the Mediterranean world, no doubt everyone outside its borders would have wildly "disapproved" of them - just as everyone internationally appears to disapprove of us now.
So, feel free to go on with your "empire" tangent, which obviously is never going to happen, which has nothing to do with anything I posted.
You were the one that brought up Pax Romana as a legitimate comparison. If the analogy brings up some unpleasant facts, I apologize. You are of course, free to wallow in your own ignorance.
