The September 2012 edition of Army Magazine has a very nice review of Find Fix Finish, by Colonel Gregory Fontenot:
Those who read Peritz and Rosenbach will have taken a good first step on the road to understanding not only what happened that enabled surprise in September 2011 but also what has happened since and the implications for U.S. counterterrorism efforts in the future. The authors are conscious that while operations are under way, certain limitations of what can be achieved exist. Much of what must be known to reach understanding remains classified, and too little is known of what the belligerents were—and are—thinking to enable thorough analysis of what they intended and how they reacted to U.S. efforts to find, fix and finish them.
