This book attempts to complete the groundbreaking and seminal study of the Vietnam War from an international perspective began by the late Ralph B. Smith in the 1980s, of which only three volumes of a projected five was completed. The most recent volume was published more than a decade ago in 1991 and it brought the story of the Vietnam War up till 1966. This book takes up the story where it stopped - The Manila Conference and the Decisions of November 1966 through to the end of the conflict in April 1975. It adopts the same 'formula/methodology' as the earlier volumes by: following a tight chronology; examining the decisions of both sides of the war simultaneously; and when appropriate relate the war to the regional and global perspective at every stage in the evolution of the conflict. The author makes use of a far greater body of communist and non-communist sources which were not available in the pre-Cold War period when Professor Smith began his study. "International History of the Vietnam War" will be of interest to students of the Vietnam War, Southeast Asian history, US foreign policy, and international history in general.
