The subject of war crimes and collective wrongdoing - whether in the name of ethnic cleansing or a more veiled form of nationalism - is in the forefront of contemporary discourse in politics, international affairs, and political philosophy. This volume addresses urgent questions about the nature of war crimes, nationalism, ethnic cleansing, and collective responsibility. In fourteen newly written essays, a distinguished team of international scholars consider war crimes and collective wrongdoing from a variety of moral, political, and legal perspectives. There is a substantial introduction from Anthony Ellis and each group of essays is followed by an afterword from the editor and suggestions for further reading. Consistently probing and provocative, War Crimes and Collective Wrongdoing promises to be of enduring interest to students and scholars alike.
