"Daveed Gartenstein-Ross has written an analytically sharp, fluidly written account of al Qaeda and its affiliates in the post–bin Laden era. It makes for sobering and essential reading."
—Peter Bergen, author of The Longest War: The Enduring Conflict between America and Al Qaeda

"Bin Laden's Legacy is an important and timely work, especially in the aftermath of bin Laden's killing. It is one of the few books to probe systematically the movement's strategy and its effect on the U.S. and its allies. Daveed Gartenstein-Ross is to be commended for his insightful analysis, and his sound policy recommendations will be of interest to scholars and policymakers alike."
—Bruce Hoffman, Director, Center for Peace and Security Studies, Georgetown University

"By an astute and penetrating analysis of al Qaeda's strategy, Daveed Gartenstein-Ross unveils the potentially devastating flaws in U.S. strategy. His recommendations must be seriously considered by policymakers and all Americans concerned with their nation's security."
—Steven Metz, U.S. Army War College Strategic Studies Institute; author of Iraq and the Evolution of American Strategy

"This book is an important contribution to the post–bin Laden debate about how to fight terrorism smarter and cheaper at a time of constraints on America's power and purse."
—Clark Kent Ervin, former Inspector General of the Department of Homeland Security

"Gartenstein-Ross's provocative arguments should push policymakers to carefully examine their assumptions about the struggle with al Qaeda. Whether you agree with his thesis, Gartenstein-Ross provides a useful counterweight to the mainstream security narrative in Washington."
—Congressman Hank Johnson (D.-Georgia), House Armed Services Committee

"Gartenstein-Ross has written an informative, contrarian, and crisply written study of al Qaeda and the U.S. response, exploring not only Iraq and Afghanistan but also important but neglected issues such as the economic dimensions of al Qaeda's strategy and the politics of U.S. counterterrorism."
—Daniel Byman, Professor, Edmund A. Walsh School of Foreign Service, Georgetown University

"A deeply researched and riveting account of the evolutionary strategy of al Qaeda and why the death of bin Laden is simply 'the end of the beginning.' Gartenstein-Ross's extraordinary work provides valuable insight on the adaptive capacity and international complexities of this non–state sponsored transnational threat, which has been able to engage in a war with the world's remaining superpower. Truly a must-read!"
—Erroll G. Southers, Adjunct Professor, University of Southern California and Associate Director, Center for Risk and Economic Analysis of Terrorism Events
