1. No one mentioned anything about Islamic countries.
2. From WWII to Vietnam to the Panama invasion, there have been SOME reports of US soldiers either raping, killing or physically assaulting unarmed civilians. The military is no different than the Police Force, there are some good cops and there are some bad cops. Years of conflict can confuse people on who the "enemy" is.
3. These horror stories of US soldiers behaving cruelly reach countries even before the soldiers land. And when they do land, of course they will have to prove themselves to the local population.
4. There are many great men and women in the US military, however there are always some bad apples.
5. Hope you can figure out a way to deal with your anger and learn how to not call people "dummies" or "terrorists" when they mention factual information.
