In practice, the theory seems to be that unmanned drones are somehow not as real as actual manned fighter jets. After all, does anyone seriously believe that Obama could send sortie after sortie of F-22s over Yemen and not have anyone complain about it? I doubt it. But as long as they're just drones, no problem. Given the inevitable growth of robotic warfare in both the near and long term, this doesn't bode well for the future.
Put drones in the hands of an executive who is empowered to do anything without any input from the other branches of government … and we have a problem indeed.
