In Vietnam , Gary R. Hess describes and evaluates the main arguments of scholars, participants, and journalists– both revisionist and orthodox in their approach – as they consider why the United States was unable to achieve its objectives. While providing a clear and well–balanced account of the existing historical debate, Hess also offers his own interpretation of the events and opens a dialogue aboutthe usefulness of historical argument in reaching a deeper understanding of the conflict. This concise book is essential reading for students and teachers of the Vietnam War as it provides a clear and well–balanced account of existing historical debate and a thought–provoking look at the futureof historical scholarship.
