From a great article by Sidney Blumenthal, Salon.com:
But how did it happen that al-Qaida in Iraq, sworn enemy of Saddam Hussein and his secularism, operating in isolation prior to 9/11, though almost certainly with the connivance and protection of Kurdish leader and current Iraqi President Jalal Talabani, has come to thrive under the U.S. occupation? And since AQI represents perhaps 1 percent or less of the insurgent strength, how can it be depicted as the main foe, capable of seizing state power? The other Sunni insurgent groups increasingly view it as an impediment to their own ambitions and have marked it for elimination. Rather than address these problematic complexities, Bush points the finger of blame at U.S. senators who dare to question his policy. "Those who justify withdrawing our troops from Iraq by denying the threat of al-Qaida in Iraq and its ties to Osama bin Laden ignore the clear consequences of such a retreat."
