This book deserves high praise. It combines detailed study of the record of the international commission which functioned in Vietnam from 1954 to 1973, with analysis of the interacting foreign policies of the three states represented on it. The accomplishments, which came mainly in the early years, were real. The failures, both in military and political tasks, were inevitable given the intractability of the conflict, the outside intervention by big powers, and the makeup of the commission as representative of the world's division into Western and Communist blocs and the nonaligned. The author is thorough, fair, balanced, but not afraid to express strong views.
