I served in the military. You don't seem to know much about it.
Literally any soldier? Really? The cooks? The guy at the mechanic shop? Literally any soldier?
Not everyone is going out on patrol. Not every soldier is committing a war crime. I've known dozens of people who went over seas and didn't even see a hint of action. WTF is with these wild assumptions being passed as facts.
Does it happen, for fucking sure. But not at the level you seem to be implying. Not at all. People let their emotions rule over reason way too much.
