How They Survived and Why We Lost: Central Intelligence Agency Analysis 1966: The Vietnamese Communists' Will to Persist

The Vietnam war began for the United States in 1954; by 1966 the Central Intelligence Agency undertook a major analysis and concluded: We cannot win in Vietnam. Their analysis was kept secret for 40 years and not released -- with redactions -- until 2006. A second version -- with additional redactions -- was released in 2016. Their analysis was a tragic and accurate prophecy unheeded. Now published for the first time.
