This collection of essays cuts to the quick of the most pressing moral issues facing decision-makers today, from the actions of ordinary soldiers in a combat zone to presidents deciding when and where to use force. Ethics lie at the heart of human and therefore also international affairs, compelling nations to get involved "over there" and dedicate resources to intervention or to justify detachment. The politics and rhetoric of ethics constrain decision-makers, greatly complicating international situations. This third edition of Ethics and Statecraft addresses the moral reasoning behind the art of peacemaking as well as the ethics and statecraft of conducting war. The coverage ranges from historical transformations of whole eras of diplomatic and international history to issues of ethics of bombing and the laws of war. Specific attention is paid to emerging issues such as armed humanitarian intervention and sanctions, drone wars, war crimes, and economic justice. The work is ideally suited for undergraduate and graduate students of international relations, history, political science, and ethics. It will also be useful for NGO officials and military officers struggling with these issues in the field. General readers will find illumination of highly relevant historical issues—including Allied bombing of civilians during World War II—that set precedents for both expansion and limitations on the laws of war. They will also encounter pressing modern-day quandaries, such as the conditions that permit or even require military or humanitarian intervention, and the impact of new technologies on old moral problems.
