Decoding Al-Qaeda's Strategy

Thomas W. Lippman, author of Saudi Arabia on the Edge:
Knowledge of the enemy is essential in any conflict, and Ryan delivers. His analysis of al-Qaeda's theology, strategy, tactics, and ability to marshal support even among people who disapprove of its methods is timely, well written,deeply researched, and ultimately reassuring.

Brynjar Lia, Norwegian Defence Research Establishment, author of Architect of Global Jihad: The Life of Al-Qaeda Strategist Abu Mus'ab Al-Suri:
A highly readable account of the evolution of al-Qaeda's strategic thinking. Drawing upon existing scholarship and new primary sources, Ryan offers not only a lucid exposé of al-Qaeda's key strategic thinkers and their works but also new insight into the logic and rationale informing al-Qaeda's violent campaigns.

General Michael Hayden, former director of the CIA:
Osama bin Laden is dead, al-Qaeda 'prime' in Pakistan is decimated, and yet the anti-Western jihad continues as extremism erupts in Yemen, Libya, Syria, Algeria, and elsewhere. Unless we can match our tactical successes with strategic progress, we seem condemned to endless war. Thankfully, Ryan shows us a way forward in his thoughtful, non-polemic analysis of this enemy's doctrine and motivation—the essential first step in combating not just its actions but also its ideas. This book is a blueprint for taking our fight to the next level.

Bruce Riedel, senior fellow at the Brookings Institution:
Michael W. S. Ryan's illumination of the ideology and strategy of al-Qaeda as seen in the writings of its key theoreticians is unique and valuable. This is an important and insightful book that provides both new information on al-Qaeda and new commentary on its strategy and how to defeat it.
