Why not just put him back in that hole?
And let the Shiites have first crack at him, or better yet, put the Kurds, Shiites and Suuni militias at equal distance from the hole, say 10 miles, clear every building and human being out of those 10 miles, then announce that whoever gets to the hole first can have him and make the new government. Then while they're doing that, (after making sure that he's not rescued by anyone but the Sunni's, if they get there first.) It would be no holds or weapons barred, we stay out of it and while they're doing that pull our troops out of the country, dump the quantanamo bay prisoners right in the middle of the race naked and unarmed.
We could have satellites monitoring the whole shebang on pay per view!
