I think that even IF the Jihadis go home, the Sunnis and Shiites will continue to kill each other in a power grab for the oil.
Your point about attracting extremists is true but the Jihadis have actually even said that Shiites are a greater enemy than "the one without" (us).
It is my prediction that this war will continue for 20 years or more, and hundreds of thousands of Iraqis will die, and that is with no Americans there. I do think we abandoned the Iraqis -- read their blogs, their pleads that we not "abandon" them, in the same way that New Orleanians feel abandoned. Iraq the Model is very pro-American, but this guy is definitely not liking America but then said this:
P.S. to the U.S. Government.
Thank you for getting rid of Saddam’s Tyranny, No thanks for not having a plan B.
Your not free to go back home until you clean up your mess!

They're going to hate us for a very long time . . .
(BTW -- I realize that 80% of Iraqis want us to leave, but I still think they will say after the fact that we abandoned them)
