Divided Responsibility: Lessons from U.S. Security Sector Assistance Efforts in Afghanistan [open pdf - 6MB]
From the Executive Summary: "After 17 years of U.S. involvement in Afghanistan and security-related U.S. appropriations totaling $83.3 billion (approximately 63 percent of the nearly $133 billion of U.S. reconstruction funding), there is not one person, agency, country, or military service that has had sole responsibility for overseeing security sector assistance (SSA). Instead, the responsibility for security sector assistance was divided among multiple U.S. and international entities. This report examines how these divides had unintended consequences and created challenges to the effectiveness of the mission, as well as some benefits."
