Vietnam: The Vietnam War

The Vietnam War

By late 1961, the Viet Cong had won control of virtually half of South Vietnam with little local opposition. The United States increased its military and economic aid to combat the Communist threat and at the same time put pressure on President Diem for democratic reforms. In Apr., 1961, Diem was reelected president, but many voters boycotted the election. Resentment against the government was dramatized by the Buddhist crisis, which erupted in May, 1963, as a result of government persecution. A number of self-immolations by Buddhist monks followed. Large antigovernment demonstrations provoked police shootings, mass arrests, and more repressive government measures. These actions, along with the increasing loss of territory to the Viet Cong, prompted Diem's own military commanders to resort to a coup (Nov. 1, 1963), in which Diem and his brother, Ngo Dinh Nhu (who headed the secret police), were murdered. A period of great political instability followed, with frequent changes in government, mounting disorders, and continued religious unrest (both Buddhist and Catholic).

In 1964 regular units of the North Vietnamese army began infiltrating into South Vietnam by way of what came to be known as the Ho Chi Minh Trail in Laos. The guerrilla conflict expanded into open warfare. The United States, deeply committed to the support of the non-Communist government of South Vietnam, became increasingly involved militarily, sending troops and then engaging in systematic bombing (see Vietnam War). The U.S. bombing of North Vietnam began after two U.S. destroyers were reportedly attacked (Aug., 1964) by North Vietnamese torpedo boats in the Gulf of Tonkin. The bombing was directed at military and industrial targets and extended to Hanoi and Haiphong.

In June, 1965, a military junta came to power with Gen. Nguyen Van Thieu as chief of state and Air Vice Marshal Nguyen Cao Ky as prime minister. Their regime was strengthened by the capture (1966) of Buddhist rebel strongholds in Da Nang and Hue. A new constitution (approved Mar., 1967) provided for a strong executive and a bicameral legislature. In Sept., 1967, Thieu and Ky were elected president and vice president respectively. The problems they faced were aggravated by the rapidly accelerating war. Heavy fighting in the rural areas forced thousands of people to seek refuge in the cities, where serious overcrowding ensued. Heavy damage was sustained in the Tet offensive of early 1968, especially in Hue and in the Saigon area.

Later in 1968 the United States, in response to increasing pressure by the American public, began a policy of “de-escalation.” In Mar., 1968, raids north of latitude 19°N were halted to promote peace negotiations, and in Nov., 1968, all bombing ceased. Peace talks between the United States and Hanoi were begun in Paris. During this time, South Vietnam had become increasingly dependent upon U.S. aid, which reached massive proportions, and the presence of U.S. troops, whose numbers peaked at almost 550,000 in 1969 dislocated the traditional agricultural economy. Peace talks made little headway, and in early 1970 U.S. “protective action” air strikes against military installations south of latitude 19°N were resumed, as well as air strikes against North Vietnamese forces in Laos and Cambodia.

In Oct., 1971, President Thieu of South Vietnam was reelected for another four-year term; he ran unopposed as other candidates, fearing a rigged election, refused to participate. In his second term President Thieu faced serious problems. The gradual withdrawal of U.S. troops, which had begun in 1969, adversely affected the economy, bringing a severe recession. At the same time, the endless war fed a raging inflation. In Apr., 1972, in response to a major Communist drive from North Vietnam, the United States reinstituted mass bombings throughout the country; Haiphong harbor and six other North Vietnamese ports, as well as rivers and canals, were mined and effectively closed to shipping. Heavy, concentrated air strikes (as many as 340 a day) continued, with one temporary halt (Oct. 24–Dec. 18), until Dec. 30, 1972, inflicting enormous damage.

The country's industrial plant was destroyed, transportation lines were cut, and many non-military targets—including the extensive system of dikes in the Red River delta and numerous residential areas—were hit. Morale nevertheless remained high; damaged transportation facilities were constantly repaired, and “ant tactics” kept supplies laboriously moving from China. Despite the declaration of a cease-fire in Jan., 1973, fighting continued. While the fighting prevented any attempt at economic recovery in the south, North Vietnam was able to begin reconstruction with foreign aid, and in less than a year the shipyards at Haiphong, the iron- and steelworks at Thai Nguyen, and many small factories were again in operation. In 1974, South Vietnam came into direct conflict with China, which seized the disputed Paracel Islands in the South China Sea.

President Thieu gradually assumed dictatorial powers; he abolished local self-government, restricted the press, arrested thousands of suspected Viet Cong sympathizers, and increased the number of executions. Mass protest demonstrations (Oct., 1974) in Saigon caused Thieu to reorganize his cabinet in an attempt to quiet the opposition. In early 1974 the constitution was amended to permit him to seek a third term in 1975, at the same time increasing that term from four to five years. During 1974 Thieu decided to abandon military defense of outlying areas, which were becoming increasingly difficult to hold without the U.S. presence. In Jan., 1975, the North Vietnamese began a major offensive, and the repeated withdrawal of South Vietnamese troops quickly enabled the North Vietnamese forces to gain a decisive advantage. By April President Thieu resigned and fled to Taiwan, the remaining government of South Vietnam surrendered, and the North Vietnamese entered Saigon without opposition.
