Is George W. Bush to blame for ISIS?

[Frodo]

No -I blame primarily Presidents Nouri al-Maliki and Barack Obama for the rise of ISIS/ISIL.  As much as Bush screwed up by invading Iraq in the first place, and compounding that by his inept handling of its immediate aftermath, the surge (and Sunni Awakening) helped rectify many of his mistakes -for which I credit him.  And had President Obama followed through by securing a status of forces agreement with the Iraqi government, we wouldn't be in this position today.  Maliki would have been constrained by the presence of American troops from going after the Sunnis, and the ISIS would have been contained in Syria.
