War and Aftermath in Vietnam [PDF ebook] 

This book, first published in 1991, attempts to combine a broad understanding of the background to the conflict in Vietnamese and world history with detailed material on US military tactics and the failure of pacification. There are chapters on the US presidential administrations of Johnson, Kennedy and Nixon; religion, culture and society in North and South Vietnam, and the nature of the ‘People’s Revolutionary War’.
