An award-winning foreign correspondent illuminates the flip-side of the Shia revival, the profound dislocation and destabilization of the Sunni Muslims and its impact on the politics and culture of the Middle East. Two million Sunni Muslims displaced or exiled by the conflict in Iraq have spread across the Middle East, unbalancing that sensitive region. From Ammam, Jordan to Beirut and particularly to Damascus in Syria Deborah Amos - an award-winning correspondent for America's National Public Radio - follows the impact of one of the great migrations of modern times. The history of the Middle East tells us that one of the greatest problems of the last forty years has been that of a displaced population, angered by their inability to safely return home and resume ownership of their property - as they see it. A new population of exiles as large as the Palestinians has been created, and the impact of the Iraqis outside Iraq is being felt across the region. But this particular disappointment also re-inflames a conflict between Sunni and Shia that has raged for many centuries.
