Western Libya has always been a hot bed for Islamic extremist, takfiris in particular. So you can bet they make up a large percentage of the so called rebels. There is less justification for this war then there was for Iraq. Saddam atleast had a history of attacking other countries, Gadhafi's Libya has never done that, what is going on now is a domestic issue in Libya. For the West to decide who gets to rule Libya is absurd and criminal.
