This book challenges the traditional approach to international law by concentrating on international hThis book challenges the traditional approach to international law by concentrating on international humanitarian law and placing the focus beyond States: it reflects on current legal, policy and practical issues that concern non-State actors in and around situations of armed conflict. With the emergence of the nation-State, international law was almost entirely focused on inter-State relations, thus excluding - for the most part - non-State entities. In the modern era, such a focus needs to be adjusted, in order to encompass the various types of functions and interactions that those entities perform throughout numerous international decision-making processes. The contributions that comprise this volume are oriented towards a broad readership audience in the academic and professional fields related to international humanitarian law, international criminal law, international human rights law and general public international law.

The essays selected for the first part of this volume offer an insight into the development, as distinguished from the history, of international humanitarian law. The focus of the majority of the works reprinted here is on an analysis of the adequacy of the law as it stood at the time of the respective publication and in the light of existing contemporary armed conflicts and military operations. Thus, the reader is afforded an in-depth look at the early roots of international humanitarian law, the continuing relevance of that body of law despite advances in weapons technology and the efforts to progressively develop it. International humanitarian law's development cannot be considered in isolation from its principles. The essays selected for the second part of the volume deal with the two fundamental principles underlying all of international humanitarian law: humanity and military necessity. The articles on the principles of humanity include reflections on the famous Martens Clause, and the analyses of military necessity take no account of 'Kriegsraison'. Moreover, they offer proof of the customary character of the principle of distinction in land, air and naval warfare.

The Law of Armed Conflict traditionally regulates the actions of States and armed groups, as well as individuals who participate in hostilities. It is increasingly evident that there are significant legal issues regarding the application of this law to the activities of International Military Missions, especially with regard to United Nations forces and other international organisations because it is unclear how their activities are regulated by traditional sources of International Law. The book explores the legal developments in addressing this challenge, including pertinent issues of human rights and international criminal law, elucidating the rights and obligations of all the actors, including States, international organisations and individuals, involved in International Military Missions.

The principle of proportionality is one of the corner-stones of international humanitarian law. Almost all states involved in armed conflicts recognize that launching an attack which may cause incidental harm to civilians that exceeds the direct military advantage anticipated from the attack is prohibited. This prohibition is included in military manuals, taught in professional courses, and accepted as almost axiomatic. And yet, the exact meaning of the principle is vague. Almost every issue, from the most elementary question of how to compare civilian harm and military advantage, to the obligation to employ accurate but expensive weapons, is disputed. Controversy is especially rife regarding asymmetrical conflicts, in which many modern democracies are involved. How exactly should proportionality be implemented when the enemy is not an army, but a non-state-actor embedded within a civilian population? What does it mean to use precautions in attack, when almost every attack is directed at objects that are used for both military and civilian purposes? In Proportionality in International Humanitarian Law, Amichai Cohen and David Zlotogorski discuss the philosophical and political background of the principle of proportionality. Offering a fresh and comprehensive look at this key doctrine, they comprehensively discuss the different components of the proportionality "equation" - the meaning of "incidental harm" to civilians; the "military advantage" and the term "excessive". The book proposes the debates over the principle of proportionality be reframed to focus on the precautions taken before the attack along with the course States should follow in investigations of the violations of the principle.

This fully updated second edition the work previously known as The Handbook of Humanitarian Law in Armed Conflicts sets out an international 'manual' of humanitarian law in armed conflicts accompanied by case analysis and extensive explanatory commentary by a team of distinguished and internationally renowned experts. Topics examined include the historical development, legal basis, and scope of application of international humanitarian law; methods and means of combat; protection of the civilian population, and of the wounded, sick or shipwrecked, and of prisoners of war; the protection of cultural property; the law of neutrality; and the enforcement of international humanitarian law. This edition also incorporates new chapters covering the law of non-international armed conflicts and international peace operations. Highly topical issues including the role of the UN security council, the relevance of International Humanitarian Law in peacetime and post-conflict military operations, and enforcement through trials for war crimes in national and international courts are also discussed.

Increasingly, war is and will be fought by machines – and virtual networks linking machines - which, to varying degrees, are controlled by humans. This book explores the legal challenges for armed forces resulting from the development and use of new military technologies – automated and autonomous weapon systems, cyber weapons, “non-lethal” weapons and advanced communications - for the conduct of warfare. The contributions, each written by scholars and military officers with expertise in International Humanitarian Law (IHL), provide analysis and recommendations for armed forces as to how these new technologies may be used in accordance with international law. Moreover, the chapters provide suggestions for military doctrine to ensure continued compliance with IHL during this ever-more-rapid evolution of technology.
