I first became interested in Ho Chi Minh in 1964-1965 while I was stationed at the U.S. Embassy in South Vietnam as a foreign service officer with the Department of State. The government in Saigon was at the point of collapse and the [Lyndon] Johnson administration was preparing to send U.S. combat troops to prevent a communist victory there. I became convinced that the U.S. effort would not succeed because of the lack of conviction in the Saigon government compared to the discipline and sense of self-sacrifice among the Viet Cong.
