According to this report, the top three leaders of Islamic State are Iraqis: one from Al Qaeda in Iraq (AQI); and two Sunni ex-generals from Saddam's army.
The leader and religious figurehead of IS, born Awwad Ibrahim Ali al-Badri al-Samarrai, (aka Abu Bakr al-Baghdadi, aka Caliph Ibrahim), was captured in 2004 or 2005 and released in 2009 under "unknown" circumstances. (Smooth move!)
The two Sunni generals, we can surmise, almost certainly lost their jobs after Dubya's Coalition Provisional Authority issued an order on May 15, 2003 to dissolve the 250,000-man Iraqi army, a day after the order to implement "De-Ba'athification" of all public and government posts.
So it's still correct to blame Bush.
