This book offers a timely and critical reflection on how states have responded to the test of terrorism in the long shadow of 9/11. Terrorism has become the hallmark of international relations in the early twenty-first century. This book provides a policy-focused analysis of how certain states have responded to its test by employing a range of viewpoints that encompass state level responses down to a close interrogation of the nebulous non-state actors who have orchestrated spectacular political violence in contemporary times. It engages with the challenges of terrorism from a variety of perspectives that include philosophical discourses, the perils of counterterrorism encapsulated in the death of Jean Charles de Menezes, learning in counterinsurgency, the effectiveness of counterterrorism spending, Al Qaeda's modus operandi and the threat posed by Boko Haram to Nigeria. This eclectic collection of chapters is an important contribution to the wide-ranging and contested debate about terrorism that has dominated the political discourse in the West since 2001.This book was published as a special issue of Defense and Security Analysis.
