"How has the ethics of international relations been transformed since the fall of the Berlin Wall? Ariel Colonomos takes up the question of how the various actors in the international system - whether nation-states, international organizations, or multinational corporations - can be held responsible for their actions. This book is distinguished in international ethics by its interdisciplinarity and the fruitful dialogue it engenders between empirically-based social scientific research and the range of normative theories that apply to this crucial domain of contemporary life. In this important work, Colonomos develops an original perspective on decisive ethical issues in current international affairs, which will help to guide future investigations in this area."

- Carol Gould, Professor of Philosophy and Political Science, and Director of the Center for Global Ethics and Politics, TempleUniversity

"Colonomos work stands at the crossroads between ethics, political theory, and the sociology of international relations. Through a combination of abstract reasoning and careful empirical research, he throws much light on the emergence of the demand for moral accountability in international life, both economic (as in the case of sanctions and reparations) and political. His book focuses on the surge of moral concern characteristic of the nineties but raises a host of permanent issues and provides a very valuable guide for their discussion." - Pierre Hassner, Emeritus Research Director and Research Associate at the Centre for International Studies and Research, Sciences Po, Paris, France
