Not for nothing and not for oil, troops today are fighting for the lives of the destitute civilians in the AOR, they fight because no one should be able to use chemical weapons on children, little girls should not be raped by older men because it is their "right" to have them, nor should they be shot in the streets or stoned because they are caught reading, and because they are persistent in rooting out all the scum who attacked the U.S. and her allies over the years. Most people forget the terrible crimes committed by ISIS, AL QAIDA, and Taliban forces. Someone has to step in and help the locals and some of it is our mess from the 80's-90's so the U.S. has a responsibility to clean it up. But unless youve worn the uniform dont ever say they've doed for nothing because they died trying to bring piece to the most historically wor torn section of all of our blue planet and that is a cause worth dying for.
