It is well that war is so terrible otherwise we could grow too fond of it.
I think it's from Lee.
Now with modern era weapons like fighter drones, stealth bombers and missiles, war isn't that terrible anymore. Or at least, there is a part of what is inarguably war, that can be showed without being horrible. Say, the day of fire over Bagdad. I remember very clearly seeing something vaguely called war on TV, but the show was more about fireworks.
