Well, what I meant when I was referring to the military staff committee was that it, by implication, would also have combat-ready or available forces to actually execute UN mandates itself, as opposed to having to contract those out.
What happened in the Balkans is that you actually had a fair amount of oversight—interestingly, by the UN Secretariat—over some of the decisions that were made with respect to targeting and the actions of troops on the ground, particularly with respect to safe areas. That didn't happen in Libya. In the Balkans you had NATO operating as a regional organization authorized by the council, but you had much more oversight from the UN than you had in the case of Libya.
Now, there were also problems with that. Many of the memoirs of generals from NATO countries have referred to the difficulties in getting a consensus between the UN and NATO countries on how to act in safe areas, but it did exist.
