In Humanitarian Intervention: Ideas in Action, Tom Weiss again demonstrates his unique talent for bringing conceptual clarity and rigorous analysis to pressing and messy real-world dilemmas. Protecting endangered people abroad raises thorny issues - politically, practically, and ethically. In this engaging book, Weiss offers a conceptual guide to understanding these dilemmas, and his application of these concepts to contemporary humanitarian emergencies will be useful to both scholars and practitioners alike. This is an essential book for anyone interested in humanitarian action. Martha Finnemore, George Washington University Few observers have written more, or more persuasively, than Professor Weiss, and this is his best work to date. A sensible, thorough and realistic treatment. Fernando R. Tesoon, Florida State University College of Law
