Why did violence decline in Iraq in 2007? Many credit the "surge," or the program of U.S. reinforcements and doctrinal changes that began in January 2007. Others cite the voluntary insurgent stand-downs of the Sunni Awakening or say that the violence had simply run its course after a wave of sectarian cleansing. Evidence drawn from recently declassified data on violence at local levels and a series of seventy structured interviews with coalition participants finds little support for the cleansing or Awakening theses. This analysis constitutes the first attempt to gather systematic evidence across space and time to help resolve this debate, and it shows that a synergistic interaction between the surge and the Awakening was required for violence to drop as quickly and widely as it did.
