That can be applied to people who never went to real war and base their views on Hollywood films. However the "combat addiction" among people who did go to war is still very real. There are countless stories of people who knowingly chose to go back. I think it's important to recognize that the idea "if only people knew how awful the war is, no one would go there" doesn't really work.
