Presents a comprehensive history of the U.S. program, chiefly derived from SIGIR's body of extensive oversight work in Iraq, hundreds of interviews with key figures involved with the reconstruction program, and thousands of documents. The report examines the pre-war planning for reconstruction, the shift from a large infrastructure program to a more community-based one, and the success of the Surge in 2007 and beyond. The report provides thirteen lessons applicable to contingency relief and reconstruction operations, which should create a basis for reviewing and reforming the U.S. approach to these activities.
