Personally, I think the US should do an ad blitz in Iraq and simply say that they have a choice. Either stand together as Iraqis - Shiite, Sunni and Kurd - and say no more to the killing and build a new country together with our help or we will leave and you can continue killing each other until the country is completely destroyed and your thirst for blood is satisfied. Your choice. You have 1 month to decide.
The Madhi Army is not going to stop killing neither are the Badr, the Iranians, or al-Qaeda.
We need a strong government in Baghdad willing to kill these people.
That is the only way peace can come to Iraq.
I like your idea. I don't think the killing is going to stop until one side is defeated. Right now, the Sunnis and the Shiites are settling scores and it will continue until one side gives up.
They are Muslims. They’ll choose option 2 every time.
