Will NATO (the western powers of the world) finally get rid of Gaddafi? You would think being as powerful as they are that together they would almost be impossible to stop. I guess time will soon tell. Maybe time will also show who is more powerful, the UN or NATO?
NATO's mission is not to get rid of Gaddafi. The objective of Operation Unified Protector is to enforce an arms embargo and the no fly zone.
If the alliance wanted Gaddafi dead, he would be.
