I think that’s a fair perspective and one I generally agree with. But I also see a compelling argument for “self defense.” Children are victims of war, maybe they need to be able to defend themselves in times of war at home.
It’s one thing to use child soldiers as cannon fodder or in wars of aggression, but maybe another when they’re defending their homes and themselves. I’m not sure
Granted, I just see some grey area. Home: justified. Neighborhood? City? Country? Hard to say.
