America's Failure In Vietnam

The United States intervened in Vietnam to stop the spread of Communism in Southeast Asia, and became embroiled in a decades-old struggle for control of the country. The Americans misjudged their own ability to fight a protracted guerilla conflict and underestimated the capabilities of the North Vietnamese armed forces. Political infighting at home and the growing anti-war movement across the country were also factors that led to the costly American defeat in Vietnam.
