How should we analyze and assess new terrorist behaviors? What are the particular risks and challenges from new terrorism? Should we negotiate with terrorists, and, if so, how? When should we use force against terrorists? Countering New(est) Terrorism: Hostage-Taking, Kidnapping, and Active Violence—Assessing, Negotiating, and Assaulting improves our knowledge of new terrorist behaviors, and our skills in responding to such attacks. The term "new terrorism" has been in circulation since the late 90’s. This book analyzes the "newest terrorism" that has emerged in recent years—characterized by increased hostage-taking, kidnapping, and active violence—and develops best practices for countering these emerging threats. Along the way, it challenges fashionable wishful thinking that all terrorists are open to rational negotiation or de-radicalization, that military responses always reflect badly on the official side, and that terrorists are not constrained by their own doctrines. The new terrorists are dramatically more ideological, murderous, and suicidal. They are generally less reconcilable, less trusting of official negotiators, less likely to release detainees, and more likely to kill detainees. They are less likely to demand ransoms yet more likely to release hostages in cases in which they do demand ransom. They are more informed about the official side’s policies, tactics, techniques, and procedures. They are more likely to use new information and communication technologies against responding agencies and officials. They are more capable fighters—they kill more people despite deploying fewer fighters per hostage. Most disturbing is the fact that they take advantage of free-er societies to access easier targets.
