Newly revised, this textbook provides an authoritative conceptual and practical overview of international law governing the resort to force. Following an introductory chapter, with a section on the key issues in identifying the law and actual and potential changes to it, the book addresses the breadth and scope of the prohibition of the threat or use of force and the meaning of 'force' as the focus of this. The book proceeds to address the use of force through the United Nations and regional organisations, the use of force in peacekeeping operations, the right of self-defence and the customary limitations upon this right, the controversial right of humanitarian intervention, and forcible interventions in civil conflicts. Updated to include greater focus on aspects such as cyber operations, the threat of force, and the 'human element' to the use force, as well as the inclusion of recent developments such as the 2022 Russian invasion of Ukraine, it seeks to address the contemporary legal framework through the prism of contemporary challenges that it currently faces.

When the United Nations Charter was adopted in 1945, states established a legal `paradigm' for regulating the recourse to armed force. In the years since then, however, significant developments have challenged the paradigm's validity, causing a `pardigmatic shift'. International Law and the Use of Force traces this shift and explores its implications for contemporary international law and practice.

This book explores the whole of the large and controversial subject of the use of force in international law; it examines not only the use of force by states but also the role of the UN in peacekeeping and enforcement action, and the growing importance of regional organizations in the maintenance of international peace and security. Since the publication of the second edition of International Law and the Use of Force the law in this area has continued to undergo a fundamental reappraisal. Operation Enduring Freedom carries on against Al Qaida and the Taliban in Afghanistan six years after the terrorist attacks of 11 September 2001. Can this still be justified as self-defence in the 'war on terror'? Is there now a wide right of pre-emptive self-defence against armed attacks by non-state actors? The 2006 Israel/Lebanon conflict and the recent intervention of Ethiopia in Somalia raise questions about whether the 'war on terror' has brought major changes in the law on self-defence and on regime change. The 2003 invasion of Iraq gave rise to serious divisions between states as to the legality of this use of force and to talk of a crisis of collective security for the UN. In response the UN initiated major reports on the future of the Charter system; these rejected amendment of the Charter provisions on the use of force. They also rejected any right of pre-emptive self-defence. They advocated a 'responsibility to protect' in cases of genocide or massive violations of human rights; the events in Darfur show the practical difficulties with the implementation of such a duty.

The international law on the use of force is one of the oldest branches of international law. It is an area twinned with the emergence of international law as a concept in itself, and which sees law and politics collide. The number of armed conflicts is equal only to the number of methodological approaches used to describe them. Many violent encounters are well known. The Kosovo Crisis in 1999 and the US-led invasion of Iraq in 2003 spring easily to the minds of most scholars and academics, and gain extensive coverage in this text. Other conflicts, including the Belgian operation in Stanleyville, and the Ethiopian Intervention in Somalia, are often overlooked to our peril. Ruys and Corten's expert-written text compares over sixty different instances of the use of cross border force since the adoption of the UN Charter in 1945, from all out warfare to hostile encounters between individual units, targeted killings, and hostage rescue operations, to ask a complex question. How much authority does the power of precedent really have in the law of the use of force?

This book provides a comprehensive and detailed analysis of the nature, content and scope of the rules regulating the use of force in international law as they are contained in the United Nations Charter, customary international law and international jurisprudence. It examines these rules as they apply to developing and challenging circumstances such as the emergence of non-State actors, security risks, new technologies and moral considerations.

This volume of essays examines the development of political and legal thinking regarding the use of force in international relations. It provides an analysis of the rules on the use of force in the political, normative and factual contexts within which they apply and assesses their content and relevance in the light of new challenges such as terrorism, weapons of mass destruction and cyber-attacks. The volume begins with an overview of the ancient and medieval concepts of war and the use of force and then concentrates on the contemporary legal framework regulating the use of force as moulded by the United Nations Charter and state practice. In this regard it discusses specific issues such as the use of force by way of self-defence, armed reprisals, forcible reactions to terrorism, the use of force in the cyberspace, humanitarian intervention and the responsibility to protect. This collection of previously published classic research articles is of interest to scholars and students of international law and international relations as well as practitioners in international law.

This Oxford Handbook provides an authoritative and comprehensive analysis of one of the most controversial areas of international law. Over seventy contributors assess the current state of the international law prohibiting the use of force, assessing its development and analysing the many recent controversies that have arisen in this field.
