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 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.

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.

A systematic study on the legal regulation of the use of military force, both by international organisations and states, at the beginning of the twenty-first century.

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.

The prohibition of the use of force is one of the most crucial elements of the international legal order. Our understanding of that rule was both advanced and challenged during the period commencing with the termination of the Iran-Iraq war and the invasion of Kuwait, and concluding with the invasion and occupation of Iraq. The initial phase was characterized by hopes for a functioning collective security system administered by the United Nations as part of a New World Order. The liberation of Kuwait, in particular, was seen by some as a powerful vindication of the prohibition of the use of force and of the UN Security Council. However, the operation was not really conducted in accordance with the requirements for collective security established in the UN Charter. In a second phase, an international coalition launched a humanitarian intervention operation, first in the north of Iraq, and subsequently in the south. That episode is often seen as the fountainhead of the post-Cold War claim to a new legal justification for the use of force in circumstances of grave humanitarian emergency-a claim subsequent challenged during the armed action concerning Kosovo. There then followed repeated uses of force against Iraq in the context of the international campaign to remove its present or future weapons of mass destruction potential. Finally, the episode reached its controversial zenith with the full scale invasion of Iraq led by the US and the UK in 2003. This book analyzes these developments, and their impact on the rule prohibiting force in international relations, in a comprehensive and accessible way. It is the first to draw upon classified materials released by the UK Chilcot inquiry shedding light on the decision to go to war in 2003 and the role played by international law in that context.

The internet has changed the rules of many industries, and war is no exception. But can a computer virus be classed as an act of war? Does a Denial of Service attack count as an armed attack? And does a state have a right to self-defence when cyber attacked? With the range and sophistication of cyber attacks against states showing a dramatic increase in recent times, this book investigates the traditional concepts of 'use of force', 'armed attack', and 'armed conflict' and asks whether existing laws created for analogue technologies can be applied to new digital developments. The book provides a comprehensive analysis of primary documents and surrounding literature, to investigate whether and how existing rules on the use of force in international law apply to a relatively new phenomenon such as cyberspace operations. It assesses the rules of jus ad bellum and jus in bello, whether based on treaty or custom, and analyses why each rule applies or does not apply to cyber operations. Those rules which can be seen to apply are then discussed in the context of each specific type of cyber operation. The book addresses the key questions of whether a cyber operation amounts to the use of force and, if so, whether the victim state can exercise its right of self-defence; whether cyber operations trigger the application of international humanitarian law when they are not accompanied by traditional hostilities; what rules must be followed in the conduct of cyber hostilities; how neutrality is affected by cyber operations; whether those conducting cyber operations are combatants, civilians, or civilians taking direct part in hostilities. The book is essential reading for everyone wanting a better understanding of how international law regulates cyber combat.

The prohibition of the use of force in international law is one of the major achievements of international law in the past century. The attempt to outlaw war as a means of national policy and to establish a system of collective security after both World Wars resulted in the creation of the United Nations Charter, which remains a principal point of reference for the law on the use of force to this day. There have, however, been considerable challenges to the law on the prohibition ofThe prohibition of the use of force in international law is one of the major achievements of international law in the past century. The attempt to outlaw war as a means of national policy and to establish a system of collective security after both World Wars resulted in the creation of the United Nations Charter, which remains a principal point of reference for the law on the use of force to this day. There have, however, been considerable challenges to the law on the prohibition of the use of force over the past two decades. This Oxford Handbook is a comprehensive and authoritative study of the modern law on the use of force. Over seventy experts in the field offer a detailed analysis, and to an extent a restatement, of the law in this area. The Handbook reviews the status of the law on the use of force, and assesses what changes, if any, have occurred in consequence to recent developments. It offers cutting-edge and up-to-date scholarship on all major aspects of the prohibition of the use of force. The work is set in context by an extensive introductory section, reviewing the history of the subject, recent challenges, and addressing major conceptual approaches. Its second part addresses collective security, in particular the law and practice of the United Nations organs, and of regional organizations and arrangements. It then considers the substance of the prohibition of the use of force, and of the right to self-defence and associated doctrines. The next section is devoted to armed action undertaken on behalf of peoples and populations. This includes self-determination conflicts, resistance to armed occupation, and forcible humanitarian and pro-democratic action. The possibility of the revival of classical, expansive justifications for the use of force is then addressed. This is matched by a final section considering new security challenges and the emerging law in relation to them. Finally, the key arguments developed in the book are tied together in a substantive conclusion. The Handbook will be essential reading for scholars and students of international law and the use of force, and legal advisers to both government and NGOs.

Threats of force are an inherent part of communication between some States. One prominent example is the 2017–2018 crisis in relations between the United States and North Korea, marked by multiple threats issued by both sides. Yet, despite the fact that States seem to use threats of force with unlimited freedom, they are prohibited by international law. This book presents threats of force from the perspective of the practice of States. Thus, the book is based on an examination of multiple cases when States reported threats of force. It describes what threats of force are, examines the status of the prohibition of threats of force as a legal norm, presents examples and describes the mechanisms that are available for States in case threats occur, as well as their legal consequences. The book will be an invaluable resource for academics and researchers in the areas of international security law, public international law, law of armed conflict and international relations.
