THE UNITED STATES DID NOT LOSE THE WAR IN VIETNAM, THE SOUTH VIETNAMESE DID after the U.S. Congress cut off funding. The South Vietnamese ran out of fuel, ammunition and other supplies because of a lack of support from Congress while the North Vietnamese were very well supplied by China and the Soviet Union.
Myth: The American military was running for their lives during the fall of Saigon in April 1975. The picture of a Huey helicopter evacuating people from the top of what was billed as being the U.S. Embassy in Saigon during the last week of April 1975 during the fall of Saigon helped to establish this myth. The fall of Saigon happened 30 April 1975, two years AFTER the American military left Vietnam. The last American troops departed in their entirety 29 March 1973
Myth: The United States lost the war in Vietnam.
The American military was not defeated in Vietnam. The American military did not lose a battle of any consequence. From a military standpoint, it was almost an unprecedented performance. (Westmoreland quoting Douglas Pike, a professor at the University of California, Berkley a renowned expert on the Vietnam War) [Westmoreland] This included Tet 68, which was a major military defeat for the VC and NVA.
