Iraq's political system, the result of a U.S.-supported election process, has been increasingly characterized by peaceful competition, as well as by attempts to form cross-sectarian alliances. However, ethnic and factional infighting continues, sometimes involving the questionable use of key levers of power and legal institutions. This report discusses the current political climate of Iraq and also explores speculations as to what will happen after U.S. troops completely withdraw from the region at the end of 2011.

The Kurdish-inhabited region of northern Iraq is relatively peaceful and prospering economically, but the Iraqi Kurds' political autonomy and political strength in post- Saddam Iraq is causing friction with Arab leaders in Iraq, Turkey, and Iran. However, an overall reduction in violence in Iraq, coupled with continued U.S. political influence over the Kurds, is likely to prevent a destabilizing escalation of the Iraqi Kurd-Arab disputes.

To address the challenges facing the U.S. intelligence community in the 21st century, congressional and executive branch initiatives have sought to improve coordination among the different agencies and to encourage better analysis. This report discusses these challenges and efforts the current and previous Administrations and Congresses have taken and are taking to address them. The report includes criticism of the intelligence community's efforts regarding Iraq, Iran, and other areas. Improved analysis remains a key goal in these discussions.

This report presents U.S. military casualties as well as governmental and nongovernmental estimates of Iraqi civilian, police, and security forces casualties.
