Iraq's political system, the result of a U.S.-supported election process, is increasingly characterized by peaceful competition rather than violence, but sectarianism and ethnic and factional infighting continue to simmer. This report discusses the current state of Iraq, concentrating primarily on the actions of Iraqi Prime Minister Nuri al-Maliki, efforts underway to combat sectarian violence, and the projected U.S. troop withdrawal by August 2010.

The majority of the world's Muslim population follows the Sunni branch of Islam, and approximately 10%-15% of all Muslims follow the Shiite (Shi'ite, Shi'a, Shia) branch. Shiite populations constitute a majority in Iran, Iraq, Bahrain, and Azerbaijan. Sunnis and Shiites share most basic religious tenets. However, their differences sometimes have been the basis for religious intolerance, political infighting, and sectarian violence. This report includes a historical background of the Sunni-Shiite split and discusses the differences in religious beliefs and practices between and within each Islamic sect as well as their similarities. The report also relates Sunni and Shiite religious beliefs to discussions of terrorism and sectarian violence that may be of interest to Congress.
