Don't stretch it too far
While he has some good points, his European and other examples don't project directly into Iraq. The leadership of al Qaeda in Iraq is definitely not "home-grown." Even most of the actual bombers are imported through Syria and other places. He doesn't really discuss Iraq in any detail in the presentation, so I don't want to make too many assumptions on his position, but he does make the mistake of mushing al Qaeda in Iraq and the insurgency into one lump, which is not the case, and even less so now that many former Iraqi Sunni insurgents have become virulently anti-al Qaeda.
