THE MISSION, per Donilon, is “limited in duration and scope: one, to set the conditions for the enforcement of a no-fly zone in Libya; second, to take actions to protect citizens in Libya from attack; and third, to set the conditions and open up the ability for humanitarian assistance to reach citizens in Libya. … we'll continue to monitor Qaddafi’s actions, not just his words, and continue the efforts on behalf of the international community, working with the international community to enforce the terms of United Nations Security Council 1973.
http://www.politico.com/playbook/Note: Nowhere in this statement does Donilon say, "the mission is to removed Gaddafi from power" or "the mission is to aid the rebels in removing Gaddafi from power." That may be a DESIRE, but it's (apparently) not a part of the mission.
To base one's argument on the presumption of the contrary would be inaccurate.
