Iraq's Shia Warlords and Their Militias Political and Security Challenges and Options

As America's de facto co-belligerents who often share the same battlespace in the fight against the Islamic State of Iraq and Syria, the presence and activity of Iraq's Shia warlords and their militias have an impact on U.S. interests and policies at both the strategic and operational levels. The objective of this monograph is to provide a better understanding of the Shia militia phenomenon and to highlight the factors with which U.S. policymakers and U.S. Army planners and commanders will have to deal with respect to operations in Iraq.
