This week (March 29) in 1973, the United States withdrew its last remaining combat troops from Vietnam, ending its military involvement in the Vietnam War.
It also ended what had been the United States’ professed rationale for fighting in Vietnam. As President Lyndon Johnson put it at the time, America’s objective was to preserve the independence and “self determination” of the South Vietnamese government and people.
Yet it’s highly debatable whether the U.S. government, in particular the Johnson administration, truly considered it an objective to preserve the independence and “self determination” of South Vietnam. After all, from 1961 to 1965 — that crucial period before the United States sent in combat troops and therefore ended any realistic chance of peacefully negotiating a settlement between the North and South on terms acceptable to both — not only did South Vietnam think such negotiations were possible, so did North Vietnam and its two patrons, the Soviet Union and China. The only nation opposed to North-South negotiations was the United States
To that end, from 1961 to 1965 the U.S. government strongly pressured the various South Vietnamese governments with which it was allied not to enter into negotiations. Those governments included one headed by South Vietnam’s first president, Ngo Dinh Diem, who had gained power in 1955 thanks to U.S. support. Yet in 1963, when Diem began talking of negotiating with the North and asking America to leave his country, he was replaced in a U.S.-supported coup by General Duong Van Minh.
By 1964 Minh also realized that negotiating a peaceful settlement with the North looked preferable to continuing to fight it. For his troubles he was replaced in a U.S.-supported coup by General Nguyen Khanh, who, by the end of 1964, also began hinting of a negotiated settlement with the North. As a result, in February of 1965, again with support from the United States, Nguyen Cao Ky overthrew Khanh.
