Last month, my colleagues and I travelled around the center of Iraq -- formerly the most violent part of the country -- and visited infamous places such as Eskanderia, in the so-called "Sunni triangle of death" and Fallujah, in Anbar province. Everywhere we went, we met with aid workers, local and central government officials, and of course with displaced Iraqis or families who recently returned to their homes. We spent two weeks trying to find an answer to the key question all displaced Iraqis ask themselves: Can they return home?
