Written by two leading scholars, this book is an accessible overview of the global political consequences of the 9/11 terror attacks. The War on Terror has defined the first decade of this century. It has been marked by the deaths of thousands of people, political turmoil, massive destruction, and intense fear. Regardless of the name it goes under, the long war on terror will continue to affect lives across the world. Its catalyst, 9/11, did not have to happen, nor did the character of the responses. This book offers a set of novel interpretations of how we got here, where we are, and where we should be heading. It is organised around twelve penetrating and readable essays, full of novel interpretations and succinct summaries of complex ideas and events. In their examination of those aspects of global order touched by terror, the authors argue that the dangers of international terrorism are not overblown. Future 9/11s are possible: so is a more just and law-governed world. Terrorism cannot be disinvented, but with more intelligent policies than have been on show these past ten years, it can be overcome and made politically anachronistic. This book will be essential reading for all students of terrorism studies, international security, war and conflict studies and IR in general, as well as of much interest to well-informed lay readers.
