Since Juniorbush mongered the damn war in the first place, of COURSE it is his fault. ISL is largely led by former officers in Saddam's army. Rumsfeld removed all the Baathists from power, and the Shiites were put in charge. The assumption was that men with military experience would just fade away and become purveyors of entwas and trillium or something. But no, they used their experience to organize a Sunni army. That is the way history works.
