You do not have to love or even like Assad's regime to be concerned about an organization with past ties to Al-Qaeda and ISIS taking the reins. Some people in here have a lot of faith in their newly claimed moderate stance. I do not think that a group like that changes its colors over night, but we shall see.
Us secret services seems to have won (at least Hillary's leaked emails make it seems US services got what they wanted), but since their candidate was really bad,the country split (not saying that what the French did was any better by any mean, but at least their initial candidate,pre assassination, had grassroot support.)
Still, the original Sin was French, so they're the main culprit of what happened in Lybia. Especially since it's possible that the war was started to remove witnesses of illegal campaigns fonds transferred from Gaddafi to Sarkozy, but we only have circumstancial evidence. Mostly because Gaddafi died shortly after being captured alive in the hand of french-supported rebels, his finance minister unluckily drowned himself in Vienna, and one witness retracted himself after a weird assassination attempt.
