Our politicians can't even agree on how to run *our* country, and you're expecting some people who are trying it for the first time in 30 years to have it all squared away with a snap of their fingers.The Shiites and Kurds can't even agree amongst themselves on the breakdown of their government much less to what degree there should be Sunni involvement.
It's called politics, and deal making, Dan, they'll get it all figured out over there (much to your chagrin).
