Adopting an interdisciplinary approach and drawing on the works of strategic literature and international relations theory, this book examines the theoretical nature behind a threat of force in order to inform and explain why and how the normative structure operates in the way it does. The core of the book addresses whether Article 2(4) is adequately suited to the current international climate and, if not, whether an alternative means of rethinking Article 2(4) would provide a better solution.

Threats of force are a common feature of international politics, advocated by some as an economical guarantee against the outbreak of war and condemned by others as a recipe for war. Article 2(4) of the United Nations Charter forbids states to use threats of force, yet the meaning of the prohibition is unclear. This book provides the first comprehensive appraisal of the no-threat principle: its origin, underlying rationale, theoretical implications, relevant jurisprudence, and how it has withstood the test of time from 1945 to the present. Based on a systematic evaluation of state and United Nations practices, the book identifies what constitutes a threat of force and when its use is justified under the United Nations Charter. In so doing, it relates the no-threat principle to important concepts of the twentieth century, such as deterrence, escalation, crisis management, and what has been aptly described as the 'diplomacy of violence'.

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.

The Use of Force and International Law offers an authoritative overview of international law governing the resort to force. Looking through the prism of the contemporary challenges that this area of international law faces, including technology, sovereignty, actors, compliance and enforcement, this book addresses key aspects of international law in this area: the general breadth and scope of the prohibition of force, what is meant by 'force', the use of force through the UN and regional organisations, the use of force in peacekeeping operations, the right of self-defence and the customary limitations upon this right, forcible intervention in civil conflicts, the controversial doctrine of humanitarian intervention. Suitable for advanced undergraduate and postgraduate students, academics and practitioners, The Use of Force and International Law offers a contemporary, comprehensive and accessible treatment of the subject.

Praise for previous edition: “...a comprehensive, meticulously-researched study of contemporary international law governing the use of armed force in international relations...' Andrew Garwood-Gowers, Queensland University of Technology Law Review, Volume 12(2) When this first English language edition of The Law Against War published it quickly established itself as a classic. Detailed, analytically rigorous and comprehensive, it provided an indispensable guide to the legal framework regulating the use of force. Now a decade on the much anticipated new edition brings the work up to date. It looks at new precedents arising from the Arab Spring; the struggle against the "Islamic State" in Iraq and Syria; and the conflicts in Ukraine and Yemen. It also reflects the new doctrinal debates surrounding recent state practice. Previous positions are reconsidered and in some cases revised, notably the question of consensual intervention and the very definition of force, particularly, to accommodate targeted extrajudicial executions and cyber-operations. Finally, the new edition provides detailed coverage of the concept of self-defense, reflecting recent interpretations of the International Court of Justice and the ongoing controversies surrounding its definition and interpretation.

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.
