"If any organization holds insights on the power--and the limits--of deliberation, it is the United Nations. It offers both ample proof of the relevance of policy dialogue and legal discourse in international affairs and daily examples of results born out of consultation. This timely book profits greatly from the insights collected by Ian Johnstone during his years at the General Secretariat. Combined with his penetrating analysis of sophisticated legal andpolitical theory and carefully chosen case studies, they make The Power of Deliberation a truly fascinating account of why and how argumentation influences world politics." --KOFI ANNAN Secretary-General of the United Nations (1997-2006)"In The Power of Deliberation, Ian Johnstone makes a distinctive and persuasive argument for why international law matters. In careful studies of humanitarian intervention, counter-terrorism, nuclear non-proliferation, peacekeeping and trade, he shows that international law matters because it serves as a uniquely powerful vocabulary for justificatory deliberation. States debate the law more than they follow the law. These international legal arguments shape howstates persuade each other and how they explain their actions at home, showing the extent to which the power of deliberation is the power of the better legal argument." --MICHAEL DOYLE Harold Brown Professor of International Affairs, Law and Political Science, Columbia University
