The paper examines options for managing tensions between Arabs and Kurds in northern Iraq after the withdrawal of U.S. troops in 2011. It discusses ongoing confidence-building measures implemented by the U.S. and U.N. to prevent conflict, as well as additional measures that could be taken to build trust and resolve disputes. However, it notes that without a national-level political agreement on issues like resource sharing and disputed territories, tensions are unlikely to be contained long-term. Continued U.S. and international involvement will still be needed to facilitate negotiations and prevent outbreaks of violence.
