When Iraq's Prime Minister, Nouri al-Maliki, launched an attack last week on Shiite militias in the southern city of Basra, it set off a week of heavy fighting. In the end, U.S. and British troops were called in to provide support, and the fighting spread to other cities, including Baghdad. Now, Shiite cleric Moqtada al-Sadr called on members of his militia to withdraw, in what he is calling a victory. On the show today, we'll talk about what's happened in Iraq this past week, why Sadr abruptly withdrew his forces over the weekend, and who — if anyone — can claim victory. We'll also talk about the role of U.S. troops in the fighting, and what all of this means for the future of Iraq.
