For that first part, though, what does that even mean? The military isn't gamifying things and giving folks freaking XBox achievements for racking up killstreaks or anything. It's just the same game people have been playing since putting an atlatl on a spear, a scope on a rifle, or a black powder cannon on a battlefield. How to attack the enemy without being at risk. Is it unethical for a general officer to be sitting in an operations center directing the fight by looking at real-time displays? Is that a "video game?"
The drone strikes in the Global War on Terror were a direct product of political pressure to "do something, anything" to stop another September 11th attack while simultaneously freaking out about a so-called "quagmire" any time someone mentioned "boots on ground." Well, guess what? If you don't want SOF assaulters doing raids to capture people, if you don't want traditional military formations holding ground, and you don't want people trying to collect intelligence by actually going to these places, about the only option you have left is to fly a drone around and try to identify the terrorist and then go whack him when he goes out to take a leak. Or do nothing and hope you don't get hit again.
