The ISG speaks clearly to what was wrong about the GHW Bush Administration. They are always looking for weak compromise, instead of firm principles.
I have one recommendation for the ISG. Sit the Sunni leaders in a room and tell them we're done. If they allow a bomb to go off, IED or whatever, in a Sunni controled area, Our first course of action will be to abandon them for a week. The next bomb...two weeks. We will let the Shia's rip them limb from limb until they determine they're on board and will create no more chaos. That includes promptly turning in any forgien fighters.
If they can claim that they have no control over it, begin the first week early.
Repeat in neighborhood throughout Iraq. Communities see things, they also pretend they don't see things. It's time for Iraqis to open their eyes.
Have you thought about running for president?
You may have vote.
