Vietnam War

The War In Vietnam

During WORLD WAR II, the Viet Minh, a nationalist party seeking an end to French colonial rule of Vietnam, was organized. After the defeat of the Japanese and their withdrawal from what was then known as French Indochina, the Viet Minh, under the leadership of Ho Chi Minh, formally declared independence. France refused to recognize Vietnamese independence, and war broke out between the French and the Viet Minh. In 1954 the French withdrew after suffering a devastating defeat at the Battle of Dien Bien Phu.

After the French withdrawal, participants at an international conference in Geneva, Switzerland, divided Vietnam at the 17th parallel. The Viet Minh were given control of the north, which became known as North Vietnam, while the non-Communist southern half became South Vietnam. The South Vietnamese government was headed by Prime Minister Ngo Dinh Diem, who refused to allow free elections on reunification in 1956 as agreed by the Geneva Accords. Diem rightly feared that Ho Chi Minh and the Communists would win the election. The United States supported Diem's defiance, which led the North Vietnamese to seek unification through military force.

The Diem regime, which soon proved to be corrupt and ineffective, had difficulty fighting the Viet Cong, a South Vietnamese army of guerrilla soldiers who were trained and armed by the North Vietnamese. The Viet Cong became part of the National Liberation Front (NLF), a Communist-backed insurgent organization. In 1961 President JOHN F. KENNEDY began to send more U.S. military advisers to South Vietnam, and by the end of 1962, their number had risen from 900 to 11,000. Kennedy,

however, was dissatisfied with the Diem regime and allowed a military coup to occur on November 1, 1963. Diem was assassinated during the coup, but none of the lackluster military leaders who followed him was able to stop the Communists from gaining more ground.

Direct U.S. military involvement in Vietnam began in 1964. On August 2, 1964, President LYNDON B. JOHNSON announced that North Vietnamese ships had attacked U.S. naval vessels in the Gulf of Tonkin. Johnson asked Congress for the authority to employ any necessary course of action to safeguard U.S. troops. Based on what turned out to be inaccurate information supplied by the Johnson administration, Congress gave the president this authority in the TONKIN GULF RESOLUTION (78 Stat. 384).

Johnson used this resolution to justify military escalation in the absence of a congressional declaration of war. Following attacks on U.S. forces in February 1965, he authorized the bombing of North Vietnam. To continue the protection of the South Vietnamese government, Johnson increased the number of U.S. soldiers fighting in South Vietnam from 20,000 to 500,000 during the next three years.

U.S. military leaders had difficulty fighting a guerrilla army, yet repeatedly claimed that Viet Cong and North Vietnamese forces were losing the war. On January 30, 1968, the Viet Cong and the North Vietnamese made a surprise attack on 36 major cities and towns during the Tet (lunar new year) festival. Though U.S. troops repelled these attacks, the Tet offensive undermined the credibility of U.S. military leaders and of Johnson himself, who had claimed the war was close to being won. Antiwar sentiment in the United States grew after Tet as the public became skeptical about whether the war could be won and, if it could, how many years it would take to achieve victory.

The 1968 presidential campaign of Minnesota antiwar senator EUGENE MCCARTHY gained popularity after Tet. On March 31, 1968, Johnson announced that the United States would stop bombing North Vietnam above the 20th parallel and that he would not seek reelection to the presidency. Johnson ordered a total bombing halt in October, when North Vietnam agreed to begin preliminary peace talks in Paris. These discussions dragged on during the fall election campaign, which saw Republican RICHARD M. NIXON elected president.

Nixon sought to preserve the South Vietnamese government while withdrawing U.S. troops. He began a policy of "Vietnamization," which promised to gradually transfer all military operations to the South Vietnamese. During this process the United States would provide massive amounts of military aid. In 1969, when the number of U.S. military personnel in South Vietnam had reached 540,000, Nixon announced a modest troop withdrawal. During 1969 the Paris peace talks continued with the NLF, North Vietnamese, and South Vietnamese, but little progress was made.

In the spring of 1970, Nixon expanded the war as U.S. and South Vietnamese forces invaded Cambodia to destroy North Vietnamese military sanctuaries there. The Cambodian action created a firestorm on U.S. college and university campuses, where antiwar protests led to the closing of many institutions for the remainder of the spring. Nevertheless, Nixon persevered with his policies. He authorized the bombing of Cambodia and Laos by B-52 bombers, destabilizing the Cambodian government and destroying large sections of both countries. By late 1970 the number of U.S. military personnel in South Vietnam had declined to 335,000. A year later the number had dropped to 160,000 military personnel.

In March 1972 the North Vietnamese invaded the northern section of South Vietnam and the central highlands. Nixon responded by ordering the mining of Haiphong and other North Vietnamese ports and large-scale bombing of North Vietnam. In the fall of 1972, a peace treaty appeared likely, but the talks broke off in mid-December. Nixon then ordered intense bombing of Hanoi and other North Vietnamese cities. The "Christmas bombing" lasted 11 days.

The peace talks then resumed, and on January 27, 1973, the parties agreed to a cease-fire the following day, the withdrawal of all U.S. forces, the release of all prisoners of war, and the creation of an international force to keep the peace. The South Vietnamese were to have the right to determine their own future, but North Vietnamese troops stationed in the south could remain. By the end of 1973, almost all U.S. military personnel had left South Vietnam.

The conflict in the south continued in 1974. The United States cut military aid to South Vietnam in August 1974, resulting in the demoralization of the South Vietnamese army. The North Vietnamese, sensing that the end was near, attacked a provincial capital 60 miles north of Saigon in December 1974. After the city of Phouc Binh fell in early January 1975, the North Vietnamese launched a full-scale offensive in the central highlands in March. The South Vietnamese army fell apart and a general panic ensued. On April 30 the South Vietnamese government surrendered. On July 2, 1976, the country was officially united as the Socialist Republic of Vietnam.

More than 47,000 U.S. military personnel were killed in action during the war and nearly 11,000 died of other causes. Approximately 200,000 South Vietnamese military personnel were killed, and 900,000 North Vietnamese and Viet Cong soldiers lost their lives. The civilian population was devastated by the war. An estimated 1 million North and South Vietnamese civilians were killed during the war. Large parts
