<p>In September 2001, the world witnessed the horrific events of 9/11. A great deal has happened on the counterterrorist front in the 20 years since. While the terrorist threat has greatly diminished in Northern Ireland, the events of 9/11 and their aftermath have ushered in a new phase for the rest of the UK with some familiar, but also many novel, characteristics.</p><p>This ambitious study takes stock of counterterrorism in Britain in this anniversary year. Assessing current challenges, and closely mirroring the ‘four Ps’ of the official CONTEST counterterrorist strategy – <i>Protect</i>, <i>Prepare</i>, <i>Prevent</i>, and <i>Pursue</i> – it seeks to summarize and grasp the essence of domestic law and policy, without being burdened by excessive technical detail. It also provides a rigorous, context-aware, illuminating, yet concise, accessible, and policy-relevant analysis of this important and controversial subject, grounded in relevant social science, policy studies, and legal scholarship.</p><p>This book will be an important resource for students and scholars in law and social science, as well as human rights, terrorism, counterterrorism, security, and conflict studies.</p> <p>Chapter 1 – Themes and trends</p><p>Chapter 2 – Global jihad </p><p>Chapter 3 – Domestic terrorism </p><p>Chapter 4 – Protect and Prepare </p><p>Chapter 5 – Prevent </p><p>Chapter 6 – Pursue </p><p>Chapter 7 – Threats, responses and challenges </p><p>Appendix A: Fatality-causing terrorist incidents in the UK, 2001-20 </p><p>Appendix B: Chronology of key events: 1997-2020</p>
