The end of the Cold War and the discussions concerning the process of globalization have brought the study of international politics face to face with new issues such as human rights, humanitarian interventions, environmental concerns, global social movements and health issues like HIV/AIDS. The challenges arising from these issues require novel theoretical approaches that are not limited to the traditional ethical concerns of international politics. The contributors to this volume re-examine existing approaches and formulate new ethical perspectives for the twenty-first century. This volume challenges the status quo in international relations and provides an opening for an alternative theoretical debate for those who are interested in international political theory.
