This is what the US should do...

We should let the international community take over for us. We should join the international criminal court. We should hand over the job of taking bids and assigning contract jobs to the international community. We should stop building permanent military bases in Iraq and hand the job of helping the Iraqis build their democracy to a international body that has representatives from enough different countries that any secondary agendas any of them might have will be weeded out and addressed by the body as a whole. That would be a good start.
