So is your assumption that drone strikes are deliberately targeting the innocent as a way to inspire terror? If not, isn't it obvious what the difference is?
Do you honestly expect anyone under the age of 25 to understand the geopolitics of having their family, friends, etc being killed and to realize that they were actually "bad" people and that the "proper" reaction is to simply accept the "punishment" of a drone strike?
The difference is obvious to you and me and western folks. But to the average brown kid on the ground seeing his village get blown to pieces, he aint gonna know and he'll be the one sending the bombs when he's a bigger boy. Why not use the drones and send targeted dinners to his table and he'll be a likely friend to the US in the future.
It is causing terror resentment and hatred. I don't think this is the aim though, but I actually don't know. Are aims of the drone controllers know? The linked PDF doesn't doesn't go into this area, but is very interesting. http://web.law.columbia.edu/sites/default/files/microsites/h...
