The Vietnam War occurred in Vietnam, Laos and Cambodia from 1959 to April 30, 1975.
The war was fought between the communist North Vietnam, supported by its communist allies, and the government of South Vietnam, supported by the United States of America and it's allies. This war ended in a U.S withdrawal & communist control of all of Vietnam. In Jericho, the Allied States of America claims that the Vietnam war was lost due to the U.S government's "failure of will."
