But, but don't the sunnis and the shiites hate each other? Yes, they slaughter each other on a daily basis but will band together to destroy the "Great Satan". Best example of this is a.q. kahn selling nuke stuff to iran.
Recently, I watched an interview of with a Shiite who said he was married to a Sunni (or vise versa), and that was quite common. This was on the subject: breaking up Iraq into separate "states". This solution was laid on the table by outsiders and not the Iraqi people, he stated; and, therefore, did not see how this plan could ever be successfully implemented.
