Libyan Government Troops leaving Misrata soon after armed drones sent in

Obama approves Armed Air Drones in Libya

I wasn't surprised that Libyan Government troops would stop massacring the people of Misrata soon after Obama and Nato sent in armed Air Drones that fire hellfire missiles and are capable to taking out tanks, snipers, you name it at relatively close range and relatively unseen from below. I think the United Nations and Nato might consider this as one way to prevent nations from ethnic cleansing and massacring their people in the future. So this is something to think about worldwide.  Nothing stops ethnic cleansing and massacres like the potential  assassination by armed predator air drones of the leaders ordering the ethnic cleansing and massacres in the first place.
