After masterminding the attacks of September 11, 2001, Osama bin Laden managed to vanish. Over the next ten years, as Bowden shows, America found that its war with al Qaeda--a scattered group of individuals who were almost impossible to track--demanded an innovative approach. Step by step, Bowden describes the development of a new tactical strategy to fight this war--the fusion of intel from various agencies and on-the-ground special ops. After thousands of special forces missions in Iraq and Afghanistan, the right weapon to go after bin Laden had finally evolved. By Spring 2011, intelligence pointed to a compound in Abbottabad; it was estimated that there was a 50/50 chance that Osama was there. Bowden shows how three strategies were mooted: a drone strike, a precision bombing, or an assault by Navy SEALs. In the end, the President had to make the final decision. It was time for the finish.
