Terrorism and counter-terrorism represent enduringly and globally important phenomena, and the mutually shaping relationship between non-state terrorism and state counter-terrorism continues to shape world politics. Illusions of Terrorism and Counter-Terrorism brings together leading scholars in the field to analyse this relationship, and to do so in a distinctive manner. The book sustainedly assesses the interaction of terrorism and counter-terrorism through drawing simultaneously on a range of academic disciplines in dialogue with one another; it addresses the dynamics of counter-terrorism more interrogatively and concentratedly than is common in much of the scholarly literature; and it highlights a theme that is all too rarely considered in the field: namely, the shared and mutually echoing failings and illusions involved in the politics of terrorism and counter-terrorism alike. Chapters analyse post-9/11 counter-terrorism, the ongoing evolution of al-Qaida, the imperatives and challenges and global context of western counter-terrorist efforts, and the reasons behind terrorist campaigns sometimes enduring and sometimes coming to an end. Candid and wide-ranging, Illusions of Terrorism and Counter-Terrorism offers rigorous and original argument on a subject of the highest significance.
