Face it, we've morally evolved. We've moved on. It's immoral to mow anyone down who even remotely resembles "the enemy," without necessary checks and balances carried out by rational thinkers, and not trigger pulling "drones" who kill whatever they like. We're better than that.
The only thing you left out was a staff of lawyers to prosecute our own troops for violating overly restrictive rules of engagement that get our folks killed for no good reason.
That is what your way of thinking has gotten us and one defeat after another in wars that never end.
