For me going to war offers me the ability to write about apparently very alien, sometimes hated or despised people, who've been objectified in a way that restores their humanity.

If you're young and inexperienced you might accept what people tell you, that everything's going to be fine, it's okay. It's usually other young people saying that, who don't know any better.
