If you really want to understand the confluence of Iraq, Islam, and the WOT, read Dr. Juan Cole. I've been reading him for the last three years.
Unlike Robert Spencer, Dr. Cole has been right about virtually everything pertaining to Iraq and the broader Jihaddist movement. He predicted the Iraq Civil war, when NeoCons were still high-fiving over the capture of Saddam; he articulately and correctly analyzed the roots and causes of the shia/sunni split (While NeoCons were assuring us we were "close" to Victory); and he correctly analyzes the Al Qaeda movement, in the broader context of the sunni-shia division (While NeoCons were erroneously asserting that the Al Qaeda movement is inspired by Iran and that one jihaddist warrior "is just like the next").

Oh, and in addition to having impressive academic qualifications in islamic studies; subjecting his work to expert peer-review, and to correctly predicting everything the NeoCons were wrong on......
Dr. Cole is fluent in modern standard and colloquial Arabic, Urdu and Persian, and has a command of Turkish.
And he's lived for many years and traveled extensibly in the middle east and south asia.
What were Spencer's qualifications again? Was it a master's degree in Christian studies at Univesity of North Carolina, and a stint at a rightwing thinktank?
