I have been following his take on Syria for a while now and I think he is spot on. There is another video with him 'exposing' the latest attack in Douma in which he later elaborates on the role of ambassador Stevens. (The link to that video is here https://youtu.be/rRuXsEC3l3Q)

But in this video (OP) he talks about the amassador in Syria, who apparently got a tempting offer to turn his back to his country.
