Iraq’s neighbors have influenced events in Iraq since the fall of the Saddam Hussein regime in 2003, and developments in Iraq have had political, economic, and security implications for Iraq’s neighbors and the broader Middle East. Ongoing violence in Iraq and discussion of options for modifying U.S. policy toward Iraq are fueling consideration of Iraq’s future and the current and potential policies by Iraq’s neighbors. This book provides information about current perspectives and policies of Iraq’s neighbors; analyzes potential regional responses to continued insurgency, sectarian and ethnic violence, and long-term stabilization; discusses shared concerns and U.S. long-term regional interests and reviews U.S. policy options for responding to various contingencies.
