He just can't name Saudi regime and its Wahhabiyya doctrine as salient in the discussion of ISIS

""The disappoint stems from the desire to attribute the jihadist phenomenon to a single cause rather than to several causes that work in tandem to produce it. To my mind, the most salient are these: a religious heritage that lauds fighting abroad to establish states and to protect one’s fellow Muslims; ultraconservative religious ideas and networks exploited by militant recruiters; peer pressure (if you know someone involved, you’re more likely to get involved); fear of religious persecution; poor governance (not type of government); youth unemployment or underemployment in large cities; and civil war. All of these factors are more at play in the Arab world now than at any other time in recent memory, which is fueling a jihadist resurgence around the world. ""
