40 years ago on January 27th, 1973, representatives from the U.S., South and North Vietnam signed the Paris Peace Accords. While fighting continued until the fall of Saigon in 1975, the Accords marked the end of direct U.S. involvement in Vietnam. In the 60 days following the signing of the agreement, the U.S. withdrew its remaining combat troops. This is a 1965 film titled “Why Vietnam?” produced by the U.S. Army. This film aired on ABC and in syndication as part of “The Big Picture” military history series produced from 1951 through the 1970s.
