The 'Legal Pluriverse' Surrounding Multinational Military Operations conceptualizes and examines the "Pluriverse": the multiplicity of rules that apply to and regulate contemporary multinational missions, and the array of actors involved. These operations are further complicated by changes to the classification of the conflict, and the asymmetry of obligations on participants. Structured into five parts, this work seeks, through the diversity of its authorship, to set out the web of legal regimes applicable to military operations including forces from more than one state. It maps out the ways in which different regimes interact, beginning with the laws of armed conflict and their relation to international humanitarian and human rights norms, and extending through to areas like law of the sea and environmental law. A variety of contributors systematically compile and take stock of the various legal regimes that make up the pluriverse, assessing how these rules interact, exposing norm conflicts, areas of legal uncertainty, or protective loopholes. In this way, they identify and evaluate approaches to better streamline the different applicable legal frameworks with a view to enhancing cooperation and thereby ensuring the long-term success of multinational military operations.

The past decades have seen a remarkable development of military operations both within the United Nations collective security system and in other international settings. While traditional forms of military operations have been maintained and further developed, there have also been substantive developments, responding to new challenges for international security, the specific requirements of international and multinational cooperation, and legal regulation. Treaty law, customary law, and best practice relevant for military operations derive from various branches of international law which have to be applied in context. Cooperation between States and International Organizations has brought about a progressive development of applicable rules, and a requirement for legal control both at the national and international level. At the same time, the correct application of legal rules and best practice has become one of the benchmarks for the assessmentof military operations and failure to meet appropriate standards can have significant military and political, as well as legal, implications. This makes the identification and correct application of these rules of crucial importance in the planning and conduct of all types of military operations. Theabsence of an all-encompassing set of regulations and the need to find specific solutions for tasks characterized by an interdependence of efforts have made a reassessment of this important part of international law both a timely and topical task. Renowned international lawyers have joined together in this project to offer their insight in the relevant principles and provisions. They address important rules for enforcement, peace enforcement, and peace operations, as well as for other militaryoperations conducted within the context of self-defence and other possible legal bases for the use of force.

Three experts present their perspectives on the Security Council's role in maintaining peace in a changing international order.

Since the third edition of this commentary on the Charter of the United Nations was published in 2012, the text of the Charter has not changed DL but the world has. Central pillars of the international order enshrined in the UN Charter are facing serious challenges, notably the prohibition of the use of force. Human rights, too, have come under increasing pressure, now also from contemporary information technology. Global warming poses fundamental challenges for the world community as a whole in its effort to stabilize global ecosystems. Fully updated, the commentary takes up these and other developments. It features new chapters on Climate Change and the Human Rights Council. The commentary remains the authoritative, article-by-article account of the legislative history, interpretation, and practical application of each and every Charter provision. Written by a team of distinguished scholars and practitioners, this book combines academic research with the insights of practice. It is an indispensable tool of reference for all those interested in the United Nations and its legal significance for the world community. The Commentary will be crucial in combining solid legal foundations with new directions for the development of international law and the United Nations in the twenty-first century

This handbook offers a critical and substantial analysis of maritime security and documents the most pressing strategic, economic, socio-cultural and legal questions surrounding it. Written by leading international experts, this comprehensive volume presents a wide variety of theoretical positions on maritime security, detailing its achievements and outlining outstanding issues faced by those in the field. The book includes studies which cover the entire spectrum of activity along which maritime security is developing, including, piracy, cyber security, energy security, terrorism, narco-subs and illegal fishing. Demonstrating the transformative character and potential of the topic, the book is divided into two parts. The first part exhibits a range of perspectives and new approaches to maritime security, and the second explores emerging developments in the practice of security at sea, as well as regional studies written by local maritime security experts. Taken together, these contributions provide a compelling account of the evolving maritime security environment, casting fresh light on theoretical and empirical aspects. The book will be of much interest to practitioners and students of maritime security, naval studies, security studies, maritime history, and International Relations in general. Chapter 13 of this book is freely available as a downloadable Open Access PDF at http://www.taylorfrancis.com under a Creative Commons [Attribution-Non Commercial] (CC-BY-NC)] 4.0 license.

The question of what constitutes an armed conflict has featured prominently in international law debates. However, international lawyers have paid less attention to the inextricable question of who is engaged in a conflict, focusing solely on whether there is an armed conflict. Against this backdrop, Alexander Wentker's Party Status to Armed Conflict in International Law explores why it matters and how it is established that a State, international organization, or armed group is a party to an armed conflict. The first part of the book demonstrates that party status is central at all levels of the international legal regulation of armed conflicts, with parties to armed conflict being both key addressees of international law and central reference points for regulating individuals and third parties. In response to increasingly widespread cooperation practices, the book's second part advances an analytical framework for identifying parties to conflicts with multiple parties on the same side (or 'co-parties'). Party Status to Armed Conflict in International Law is aimed at academics, students, and practitioners seeking to understand how armed conflicts are legally regulated. It presents readers with a refined account of how responsibilities are allocated in armed conflicts, enabling deeper insight into how international law can best respond to the realities of contemporary conflicts.

This book offers an accessible introduction to the U.S. military as an institution and provides insights into the military’s structure and norms. Designed for undergraduate students, the book offers an interdisciplinary overview of America’s armed forces through three critical lenses. First, it introduces the military’s constitutional and historical context. Second, it presents concise factual information chosen for its relevance to the military’s structures, procedures, norms, and varied activities. Finally, it intersperses these facts with debates, theories, and questions to spark student interest, class discussion, and further research. The text is written for the beginner but covers complex topics such as force structure and the defense budget. With contributions informed by both scholarly approaches and long military careers, the book will prepare students for further studies in international relations, civil-military relations, or U.S. foreign policy. It also encourages critical thinking, elucidating an institution that undergraduates and other civilians too often perceive as both baffling and above reproach. This book will be of much interest to students of the U.S. military, civil-military relations, U.S. politics, and public policy.
