This book offers a comprehensive yet concise take on the legal regulation of the various phases in the complex cycle of armed conflicts, from prevention to reconstruction, and covering everything in between, in particular the vast body of rules laid down in current international humanitarian law. The manual combines a general theoretical approach with modern practice in order to offer a complete picture of the law before, during and after warfareThrough a series of fourteen thematic chapters that logically follow from one to another, scholars and practitioners tackle core issues relating to the international regulation of armed conflicts, while situating them in a broader societal context. Particular attention is given to the emergence of the European Union as an increasingly important regional and global player in international peace and security. In combination with the broad scope and accessible nature of the collection, the experience and ambition on display in this volume makes it a unique reference tool for students, scholars, practitioners, civil servants, diplomats and humanitarian and human rights workers around the globe. It is complemented by, and a helpful companion to, J. Wouters and P. De Man, Humanitarian and Security Law: A Compendium of International and European Instruments.
