I asked Barry Rubin, director of the Global Research in International Affairs Center for his thoughts on the United Nations vote last night on Libya and he answered:

It completely depends on how it’s implemented. Note that it is a humanitarian, ”non-political” resolution in that it is for defense of civilians. It does call for a ceasefire. It appears that despite all the time they’ve had US policymakers haven’t decided what they want to do! So what happens now could be anything between zero and the landing of the French army in Libya. The resolution by itself is pretty meaningless unless implemented.
Qadhafi probably already has all the arms he needs so the ban on arms imports isn’t important but looks good. There isn’t any no-fly zone in place and it would take a while to do it.
So it looks good but as of today nothing is actually happening. Qadhafi might win the war before they do anything.
