In traditional situations an external military or paramilitary force working for a government that wants to influence an insurgent force sends in SOF or other forces. At a minimum, they will send in the Air Force. In either of these cases there is a human that is sharing at least part of the risk of the fight with the insurgent force. In the case of the drone there is no such shared risk.

This is a question of psychology - when trying to build long term partnerships is something lost when there is no shared risk?
