The nations that drafted the UN Charter in 1945 clearly were more concerned about peace than about justice. As a result, the Charter prohibits all use of force by states except in the event of an armed attack or when authorised by the Security Council. This arrangement has only very imperfectly withstood the test of time and changing world conditions. In requiring states not to use force in self-defence until after they had become the object of an actual armed attack, the Charter failed to address a growing phenomenon of clandestine subversion and of instantaneous nuclear threats. Fortunately although the Charter is very hard to amend, the drafters did agree that it should be interpreted flexibly by the United Nations' principal political institutions. In this way the norms governing use of force in international affairs have been adapted to meet changing circumstances and new challenges. The book also relates these changes in law and practice to changing public values pertaining to the balance between maintaining peace and promoting justice.

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.

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.

In this masterful work, both an illumination of Kant’s thought and an important contribution to contemporary legal and political theory, Arthur Ripstein gives a comprehensive yet accessible account of Kant’s political philosophy. Ripstein shows that Kant’s thought is organized around two central claims: first, that legal institutions are not simply responses to human limitations or circumstances; indeed the requirements of justice can be articulated without recourse to views about human inclinations and vulnerabilities. Second, Kant argues for a distinctive moral principle, which restricts the legitimate use of force to the creation of a system of equal freedom. Ripstein’s description of the unity and philosophical plausibility of this dimension of Kant’s thought will be a revelation to political and legal scholars. In addition to providing a clear and coherent statement of the most misunderstood of Kant’s ideas, Ripstein also shows that Kant’s views remain conceptually powerful and morally appealing today. Ripstein defends the idea of equal freedom by examining several substantive areas of law—private rights, constitutional law, police powers, and punishment—and by demonstrating the compelling advantages of the Kantian framework over competing approaches.

In this book Professor Franck tracks various conflicts since 1945 which have contributed to the extensive interpretation of the UN Charter by the UN's principal political institutions. He examines the law pertaining to the use of force againt subversion and terrorism, and the need to balance peace with justice.

This book offers a comprehensive overview of the international law applicable to cyber operations. It is grounded in international law, but is also of interest for non-legal researchers, notably in political science and computer science. Outside academia, it will appeal to legal advisors, policymakers, and military organisations.

In NATO Rules of Engagement, Camilla Guldahl Cooper offers clarity on a topic prone to confusion and misunderstanding. NATO rules of engagement (ROE) are of considerable political, strategic and operational importance, yet many of its concepts lack clarity. The resulting ambiguity may be detrimental for people involved and for mission accomplishment. Through a thorough analysis of the concept, purpose, development and use of NATO ROE, Cooper contributes to improved understanding and implementation of NATO ROE. The book covers all use of force categories and relevant law relating to the use of force during armed conflicts, including the complex concepts of hostile act and hostile intent, direct participation in hostilities, and the increasing reliance on self-defence during armed conflict.
