Humanitarian Military Intervention focuses on the questions of when and how military intervention in conflicts can achieve humanitarian benefits. It argues that an intervention can be justified only when decision makers are reasonably sure that it will do more good than harm. As the measure of success, the book develops a methodology to determine the number of lives saved. The analysis of 17 military operations in the defining cases of the 1990s-Iraq after the Gulf War, Somalia, Bosnia and Herzegovina, Rwanda, Kosovo and East Timor-reveals both successful and unsuccessful interventions in the same locations.
