The UN no-fly zone is already the subject of a UN Security Council resolution. It is being breached continually, as are the other UN Security Council resolutions. Are we going to hold the government to account for resolutions already breached? I suppose we hope that somehow they'll go along with this recent 1706 resolution, which itself requires a transition to a UN multinational protection force. If we're not enforcing other resolutions, then they're going to scoff at this resolution as well.
