9/11 and the terrorism industry

9/11 has been the trigger for a decade-long revival in research work on terrorism. The ten books under review illustrate the diversity of approaches to this growing field of study: the quality of the books does not, however, entirely refute the suggestion that there are diminishing returns to knowledge within the so-called terrorism industry. What they all share, whether orthodox or critical, is a belief in the transformative significance of September 11: how we think about these attacks and the appropriate responses remains an area of significant disagreement.
