The United Nations Collective Security System in the 21st Century: Increased Decentralization through Regionalization and Reliance on Self-Defence

Author(s):  
Giovanni Distefano

This chapter examines the provisions of the Charter of the United Nations (UN Charter) concerning the comprehensive ban on the use of force in international relations between states. It provides a legal definition of aggression and self-defence and addresses some unanswered questions concerning some of the alleged exceptions to the comprehensive ban on the use of force. It shows that the obligation not to resort to threat or use of force is not subordinated to the actual functioning of the UN collective security system and highlights the UN Charter’s establishment of substantive and institutional framework for making the prohibition on the use and threat of force between states a truly attainable goal.

The United Nations at the time of this writing has emerged from a period of uncertainty engendered by the Soviet boycotts beginning in January 1950, into blazing prominence as a fast-acting agency for suppressing armed aggression. Many of the questions raised during the first four years of its existence concerning its vitality and effectiveness as the center of a collective security system have now been dramatically answered. Its forms have altered with experience, and by analogy to our Constitution, its action in response to the armed invasion of the Republic of Korea constitutes a precedent which may rank with Chief Justice Marshall's most momentous decisions. Whatever new directions the organization and its Charter may take in response to the dynamics of the world society they represent, it is indisputable that this new parlimentary form of conducting international affairs has conclusively proved its worth and its indispensability to the future of the international community.

Abstract:If the main merit of The Internationalists is to shed light, in a powerful and convincing way, on the transformative power of rules, the role of institutions – and in particular of the United Nations and its collective security system centred around the activity of the Security Council – does not come out of the book as clearly as it might. It is submitted that the decision to concentrate upon the rule – the prohibition to use force – while limiting the attention paid to the institution – the United Nations and its collective security system – is not without consequence, particularly given the strict link existing, in the common perception, between the rule and the institution. This brief comment will focus on certain ambivalences emerging from the book about the contribution of the United Nations, as a peace-enforcing organisation, to fostering the emergence of a New World Order, as well as its continuing relevance for preserving the effectiveness of the principle on non-use of force.
