The Syrian Revolution: A Marxist account 
Salameh Kaileh: "Moreover, the bloody violence which was unleashed by the Assad regime led to the transformation of demonstrators into armed strugglers. Of course, the Assad regime benefitted immensely from this to assert that the demonstrators were fundamentalist terrorists."
Only if they are allowed to present this perspective unchallenged, which has been the case with much of the media and especially of much of the Left. I think that the Gulf involvement has made it harder to convince Alawites and Christians that Assad isn't protecting them, but I see that as more of a symptom of the underlying problem that is Assad's rule than at the core of the problem. There are much worse analyses purporting to be Marxist, and this may contain a lot of insight.
