What we've become? You think if armed drones were in the inventory during Iraq, Vietnam, Korea, or WWII they wouldn't have been used because of some lost sense of nobility?
Re-framing is incredibly powerful [1]. Operators don't kill people, they neutralize targets and complete operations.
This will always happen in a military context, and this is why it is so important to have real civilian oversight. Expedience plants the seeds of future wars.
As long as the guys frame it in terms of protecting the homeland, national security or some other vague excuse, we don't seem to care.
It's when the guys that we don't like do it that we raise hell.
It's sickening, but that's what we've become.
