Since more than 32 Iraqis are killed a day because of U.S. troop occupation and bombing, why are we horrified?

They have very "valid" justification for that and that is "iraq is a war zone" and i wonder who made it a war zone actualy ! and i don't know how the killings could be justified by just calling it a war zone?? Humen lives are equaly precious.........Ahh but i guess i m wrong ! You need to be an American if you want the world to feel sorry for you on your death !
