On the other hand, it abstracts warfare to an uncomfortable degree. While the drone pilots may grasp the full ramifications of their actions, it's a certainty that the general public does not. We see no body bags and hear no casualty reports. There are no lists of the fallen. Sending out a platoon of 18 year old kids is difficult. Sending out a squadron of MQ-9 reapers is easy.
War is horrific beyond imagining. The emotional toll has always been shared by both sides to some degree, and I would like to believe that such costs act as a deterrent. I worry about the decision-making of a society that has their portion of that horror comfortably abstracted away.
