This book is overdue and immensely valuable. The United Nations used to merit a couple of chapters in an often dry-as-dust casebook on international organizations generally, chapters devoted to the law of the Charter but never the political practice that illuminates it and makes it both trying and occasionally triumphant. Here, at last, is a volume entirely devoted to the United Nations for scholars of both international law and international relations, in an accessible format with challenging issues at every turn."-Anne-Marie Slaughter, President and CEO of the New America Foundation
