This comprehensive, landmark history chronicles our ongoing battle against al-Qa ida, the greatest threat the West has faced in the modern era. An internationally recognized authority on terrorism and counterinsurgency, Seth G. Jones presents a dramatic narrative of the on-the-ground police work; the elaborate, multiyear investigations led by the CIA, FBI, and Britain s MI5; and the shifting and deadly alliances between terrorist groups that have characterized the conflict. With gripping detail he recounts the against-the-clock hunt for the Times Square bomber and reveals startling information about Osama bin Laden s behavior during his final days. Drawing on recently declassified documents and court materials, transcripts of wiretapped conversations, and interviews with current and former government officials from the United States and key allies, Jones navigates the waves (al Qa ida attacks) and reverse waves (successful efforts to disrupt al Qa ida), explaining how we might analyze past patterns in order to successfully counter al Qa ida and its allies in the future.
