"In Syria, we are told that President Assad is the evil enemy, but then his enemies turn out to be even more evil than him."
This is not true, and Adam Curtis has fallen into exactly the trap he says he is trying to expose. Assad has committed enough crimes to be dragged before the International Criminal Court a dozen times over, yet nothing is done, because he is not an enemy the West is trying to get rid of as the dominant media narrative would have us believe. The narrative has gone along with his propaganda that he is fighting terrorists, so despite the fact that it has been the Free Syrian Army that has battled ISIS while Assad has done deals with them, ISIS are still labelled as his enemy.
Turned round, Curtis' analysis could help us see the holes in the anti-Syrian narrative of the world's media. The way in which the Russian state has provided aid for the opposition to discredit it when the funding is exposed, is like the way the Syrian opposition is condemned for accepting weapons from the Gulf states and the US, ignoring the vastly disproportionate arming of Assad by Russia and Iran.
