Clarification: I don't mean that the pilot has an itchy trigger finger, I mean the system or decision maker. I see how the two might be confused based on my original comment.
The commander/politician/leader is answerable and responsible for his soldiers, as such if the risk to the soldier's life is taken out of equation an attack suddenly begins to make more sense as it carrier lower risk & lower costs, therefore requiring less justification.
The reaper/predator and other drones cannot survive in contested airspace; any pilot(s) in modern combat aircraft would be at almost no risk of being shot down.
