Inside Terrorism by Dr. Bruce Hoffman

Bruce Hoffman’s Inside Terrorism has remained the seminal work for understanding the historical evolution of terrorism and the terrorist mind-set. In this revised third edition of his classic text, Hoffman analyzes the latest developments in global terrorism, offering insight into new adversaries, motivations, strategies, and tactics. He focuses on the rise of ISIS and the resilience of al-Qaeda; terrorist exploitation of the Internet and embrace of social media; radicalization of foreign fighters; and potential future trends, including the repercussions of a post-caliphate ISIS.

Anonymous Soldiers by Dr. Bruce Hoffman

In this groundbreaking work, Bruce Hoffman—America’s leading expert on terrorism—brilliantly re-creates the crucial thirty-year period that led to the birth of Israel. Drawing on previously untapped archival resources in London, Washington, D.C., and Jerusalem, Anonymous Soldiers shows how the efforts of two militant Zionist groups brought about the end of British rule in the Middle East. Hoffman shines new light on the bombing of the King David Hotel, the assassination of Lord Moyne in Cairo, the leadership of Menachem Begin, the life and death of Abraham Stern, and much else. Above all, he shows exactly how the underdog “anonymous soldiers” of Irgun and Lehi defeated the British and set in motion the chain of events that resulted in the creation of the formidable nation-state of Israel.

The Evolution of the Global Terrorist Threat by Dr. Bruce Hoffman

Examining major terrorist acts and campaigns undertaken in the decade following September 11, 2001, internationally recognized scholars study the involvement of global terrorist leaders and organizations in these incidents and the planning, organization, execution, recruitment, and training that went into them. Their work captures the changing character of al-Qaeda and its affiliates since the invasions of Afghanistan and Iraq and the sophisticated elements that, despite the West’s best counterterrorism efforts, continue to exert substantial direction over jihadist terrorist operations.

A Practitioner’s Way Forward by Dr. David Brannan

This book provides practitioners and analysts in the field with effective tools for conducting analysis of terrorist groups and other violent substate groups. Free from unnecessary jargon and presented in a user-friendly format, the book offers analytical perspectives and techniques that are practical as well as intellectually rigorous; accessible and instantly applicable, while also based on solid social science theory and methodology. Part handbook, part reference book, it identifies the major obstacles to effective analysis, examines the most commonly used interpretations of terrorism, and goes on to present a unified model for analysis. This model, based on insights from social psychology, is highly adaptive and can be applied by the analyst to violent substate groups across the ideological and geographical spectrum. The final chapter contains a number of such applications—ways of doing analysis using real examples—to which the reader can refer for clarification and guidance.
