The Security Council Resolution on Libya
The United Nations Security Council Resolution on the situation in Libya is available online. In summary it authorizes member states to act as required to prevent harm to Libyan civilians, authorizes the establishment of a no-fly zone in Libyan air space, strengthens the arms embargo against Libya, and strengthens the freeze on Libyan assets in foreign banks.
It does not authorize member states to support rebels, defend armed insurgent groups, remove Qaddafi from office, or take steps to prevent Qaddafi’s use of mercenaries.
President Obama has underscored that understanding of the resolution:
Secretary of State Hillary Rodham Clinton is traveling to Paris on Saturday for a meeting with European partners about enforcement of the U.N. resolution, Obama announced.
He pledged that the United States will not deploy ground troops in Libya, “and we are not going to use force to go beyond a well-defined goal, specifically the protection of civilians within Libya.”
The emphasis is mine.
If you support U. S. participation in the actions authorized under the resolution on the grounds that it will remove Qaddafi from power, I don’t quite see how you can draw that conclusion from the resolution or from President Obama’s remarks on it.
