I can't believe you would say these things and advocate killing more innocents, even if you're just playing devils advocate! And you got modded up too. But even worse you pass judgements on individuals you know nothing about.
I guess you haven't read up on the drone pilot news lately then. Burn-out is super high because drone pilots do have consciences. One guy talked[1] about being ordered to fire on some bad guys, shooting a missile at them, and then watching as one of them bled to death in the sand. On IR camera he could see the guy slowly get cold. That was more traumatic than you and I know. The effects of this and other incidences on this pilot have led to debilitating emotional difficulties. And that's not an uncommon experience.
Now this same pilot, had he been over in Afghanistan, in the thick of things, and under real danger and fire could have killed without remorse. The justification would be as much self defense as anything. But far removed from the action, the trauma of killing was much much more intense. And then going home afterward to a "normal" life with the wife an kids just amplifies the trauma for many personnel.
If you want to target the inhuman American war machine, go ahead. War crimes are war crimes, no doubt about it. But to claim drone pilots have no conscience is just wrong.
