This book examines one of the most important challenges facing the United Nations today: the effective and lawful use of force by or under the authority of the UN to maintain or restore peace. It makes a significant contribution to the content of the law pertaining to the use of force by the UN and provides guidance as to the likely future developments in the legal framework governing collective action to maintain peace under the auspices of the United Nations.

This text examines one of the most important challenges facing the United Nations - the effective and lawful use of force by or under the authority of the UN to maintain or restore peace.

Is there any hope for those who despair at the state of the world and the powerlessness of governments to find a way forward? Global Governance and the Emergence of Global Institutions for the 21st Century provides ambitious but reasonable proposals to give our globalized world the institutions of international governance necessary to address effectively the catastrophic risks facing humanity that are beyond national control. The solution, the authors suggest, is to extend to the international level the same principles of sensible governance that exist in well-governed national systems: rule of law, legislation in the common interest, an executive branch to implement such legislation, and courts to enforce it. The best protection is unified collective action, based on shared values and respect for diversity, to implement widely accepted international principles to advance universal human prosperity and well-being.

The role of the United Nations in collective security has been evolving since its inception in 1945. This book explores collective security as practiced within the legal framework provided by the United Nations Charter, with a particular focus upon activity undertaken under the auspices of the UN Security Council, the body conferred by the Charter with the primary responsibility for the maintenance of international peace and security. Although the book is primarily grounded in international law, where appropriate it also draws upon relevant political insights in order to present a clear picture of the UN collective security system in operation and the factors which impact upon the way in which it functions. Offering a comprehensive analysis it considers the full range of measures which can be utilised by the UN in the performance of its collective security remit including military enforcement action, peacekeeping, non-military sanctions and diplomacy. The book considers each of these measures in detail, assessing the legal framework applicable to the form of action, the main legal controversies which arise in respect of their appropriate utilisation, and the UN’s use of this collective security ‘tool’ in practice. The book draws conclusions about the main strengths and shortcomings of the various means through which the UN can attempt to prevent, minimise or end conflict.

In 2004, the Report of the Secretary-General's High-Level Panel on Threats, Challenges and Change emphasised the linkages between economic development, security and human rights, and the imperative in the twenty-first century of collective action and cooperation between States. In a world deeply divided by differences of power, wealth, culture and ideology, central questions today in international law and organisation are whether reaffirmation of the concept of collective security and a workable consensus on the means of its realisation are possible. In addressing these questions, this book considers the three key documents in the recent UN reform process: the High-Level Panel report, the Secretary-General's In Larger Freedom report and the 2005 World Summit Outcome document. The chapters examine the responsibilities, commitments, strategies and institutions necessary for collective security to function both in practice and as a normative ideal in international law and relations between state and non-state actors alike.

This book examines the development of collective security by regional organisations particularly after the Cold War. It analyses the various constitutional developments that have occurred within regional arrangements such as ECOWAS, African Union, SADC, OAS, and NATO and critically analyses how these developments have propelled regional organisations to depart from the normative framework of regional arrangement contained in Chapter VIII of the UN Charter. Through a comprehensive examination of practice, the book evaluates the impact of regional organisations' newly asserted powers to authorise enforcement action and determine when situations within member states warrant their intervention. It inquires into the legal justifications for these developments both from within the UN Charter and regional treaties and practice and asks whether consensual intervention, that is the use of force by regional organisations on the basis of their members' consent, contravenes or constitutes an exception to the prohibition of the use or threat of force under Article 2(4) of the Charter. The book also analyses the regime of complementarity between the UN and regional organisations.

This study analyzes the original intentions of the creators of the United Nations for a collective security arrangement to provide for international peace and security. The study answers the questions: What kind of world order was the United Nations designed for? What was the perceived threat that the United Nations was designed to meet? What role was envisioned for the Security Council? Under what conditions did the United Nations envision the need for force? How was force through the United Nations be used - specifically, what kind of force and what type of control would there be over this force? The study does a focused comparison between the 1943-1945 period and the current situation to determine if the 1943-1945 period is an appropriate historical analogy for a current assessment of the United States role in the United Nations. The study begins with a historical overview of the development of the United Nations, followed by a detailed discussion of the UN collective security plan. The study next looks at the current world situation with regard to the need for collective security, exploring what kind of world order is emerging and evaluates current threats. The study concludes with an analysis of how well the original UN collective security plan meets the current needs of the world system.

This is the first major exploration of the United Nations Security Council's part in addressing the problem of war, both civil and international, since 1945. Both during and after the Cold War the Council has acted in a limited and selective manner, and its work has sometimes resulted in failure. It has not been - and was never equipped to be - the centre of a comprehensive system of collective security. However, it remains the body charged with primary responsibility for international peace and security. It offers unique opportunities for international consultation and military collaboration, and for developing legal and normative frameworks. It has played a part in the reduction in the incidence of international war in the period since 1945. This study examines the extent to which the work of the UN Security Council, as it has evolved, has or has not replaced older systems of power politics and practices regarding the use of force. Its starting point is the failure to implement the UN Charter scheme of having combat forces under direct UN command. Instead, the Council has advanced the use of international peacekeeping forces; it has authorized coalitions of states to take military action; and it has developed some unanticipated roles such as the establishment of post-conflict transitional administrations, international criminal tribunals, and anti-terrorism committees. The book, bringing together distinguished scholars and practitioners, draws on the methods of the lawyer, the historian, the student of international relations, and the practitioner. It begins with an introductory overview of the Council's evolving roles and responsibilities. It then discusses specific thematic issues, and through a wide range of case studies examines the scope and limitations of the Council's involvement in war. It offers frank accounts of how belligerents viewed the UN, and how the Council acted and sometimes failed to act. The appendices provide comprehensive information - much of it not previously brought together in this form - of the extraordinary range of the Council's activities. This book is a project of the Oxford Leverhulme Programme on the Changing Character of War.

The Charter of the United Nations was signed in 1945 by 51 countries representing all continents, paving the way for the creation of the United Nations on 24 October 1945. The Statute of the International Court of Justice forms part of the Charter. The aim of the Charter is to save humanity from war; to reaffirm human rights and the dignity and worth of the human person; to proclaim the equal rights of men and women and of nations large and small; and to promote the prosperity of all humankind. The Charter is the foundation of international peace and security.
