If there was a single person with a brain running the show, we'd partition Iraq and give the peices to the neighbors which lent a hand in it's destruction:

1/3 To Kuwait
1/3 to Saudi Arabia
1/3 to Turkey

Then we get out and turn a blind eye to Brutal Repression of Insurgency Eastern Style.

It all used to be Turkey anyway, and it was The UK's asinine partition of The Ottoman Empire that started all this for the most part, so I vote we give most back to Turkey, and say "Sorry about or British Friends back in 1918, They were Empire Happy. If we'd have known better we'd have sided with You and Germany and avoided alot of this heartache."
