By February 2007, contact with insurgents dropped almost 70 percent in number since June 2006 as well as decreasing in complexity and effect. By the summer of 2007, fighting in Al Anbar was mostly over. Frederick Kagan, resident scholar at the American Enterprise Institute, called Al Anbar "the Gettysburg of this war, to the extent that counterinsurgencies can have such turning points," writing "Progress in Anbar and throughout the Sunni community has depended heavily on a skillful balance between military force and political efforts at the local level."
