Which statement explains this rise in the number of U.S. troops in Vietnam during the 1960s

During the early 1960s, the U.S. military presence in Vietnam escalated as corruption and internal divisions threatened the government of South Vietnamese President Ngo Dinh Diem.

After World War II, the French tried to re-establish colonial control over a region known as French Indochina—today the countries of Vietnam, Cambodia, and Laos. Following the defeat of the French, Vietnam was partitioned by the Geneva Accord of 1954 into Communist North Vietnam and non-Communist South Vietnam. The United States supported a military government in the South and the decision of its leader, Ngo Dinh Diem, to prevent free elections, which might result in the unification of the country under the control of the Communists. Guerilla forces supported by the Communist government of the North initiated a series of attacks in South Vietnam, and the Geneva Accord began to crumble.

The Domino Theory

American foreign policy after World War II was based on the goal of containing Communism and the assumptions of the so-called "domino theory"—if one country fell to Communism, the surrounding countries would fall, like dominoes. In response to that threat, the Southeast Asia Treaty Organization (SEATO) was formed in 1955 to prevent Communist expansion, and President Dwight D. Eisenhower sent some 700 military personnel as well as military and economic aid to the government of South Vietnam. The effort was foundering when John F. Kennedy became president.

Internal Divisions

Corruption, religious differences, and mounting successes by the Vietcong guerrillas weakened the South Vietnamese government of Ngo Dinh Diem. Diem was Catholic, and public protests over the repression of Buddhists threatened the stability of his regime. Kennedy accelerated the flow of American aid and gradually increased U.S. military advisers to more than 16,000. At the same time, he pressed the Diem government to clean house and institute long-overdue political and economic reforms.

The situation did not improve. In September of 1963, President Kennedy declared in an interview, "In the final analysis, it is their war. They are the ones who have to win it or lose it. We can help them, we can give them equipment, we can send our men out there as advisers, but they have to win it, the people of Vietnam, against the Communists... But I don't agree with those who say we should withdraw. That would be a great mistake... [The United States] made this effort to defend Europe. Now Europe is quite secure. We also have to participate—we may not like it—in the defense of Asia."

The Overthrow of Diem

A few weeks later, on November 1, 1963, the South Vietnamese government was overthrown. The coup had the tacit approval of the Kennedy administration. President Diem was assassinated, after refusing an American offer of safety if he agreed to resign.

In the final weeks of his life, President Kennedy wrestled with the future of the United States' commitment in Vietnam. Whether he would have increased military involvement or negotiated a withdrawal of military personnel still remains hotly debated among historians and officials who served in the administrations of President Kennedy and President Lyndon B. Johnson.

A Domino Falls

United States military aid to Vietnam increased during 1964. By 1965, President Johnson authorized US troops to begin military offensives and started the systematic bombing of North Vietnam. By 1968, the number of US forces surpassed 500,000. During that year's presidential campaign, Americans were deeply divided by the deteriorating military and political situation in Vietnam.

In May 1968, President Johnson announced that formal peace talks would soon begin in Paris. The talks stalled during the last eight months of Johnson's presidency, and the deadlock continued during the early years of Richard Nixon's administration. Finally, in January 1973, an agreement was reached, and President Nixon ordered an end to all US offensive actions against North Vietnam.

In January 1975, North Vietnam began massive invasions of South Vietnam. A few months later, the North Vietnamese captured the capital city of Saigon, and the last Americans were evacuated from the US embassy. The American war in Vietnam was over. More than 3 million Vietnamese and 58,000 Americans had lost their lives.

Overview

Topic: The Cold War

Grade Level: 9-12

Subject Area: US History

Time Required: 12 hours (or one class period)

Goals/Rationale

In the winter of 1963, the eyes of most Americans were not on Vietnam, though it would soon become a battleground familiar to all. In this lesson, students analyze a letter to President Kennedy from a woman who had just lost her brother in South Vietnam and then consider Kennedy’s reply in which he explains his rationale for sending US military personnel there.

Essential Question

What were the origins of US involvement in Vietnam prior to its engagement of combat troops?

Objectives

Students will:

  • analyze primary sources.
  • discuss US involvement in the Vietnam conflict prior to 1963.
  • evaluate the “domino theory” from the historical perspective of Americans living in 1963.

Preparation

Prior Knowledge

Students should have a working knowledge of the Cold War. They should be able to analyze primary sources.

Historical Background and Context

After World War II, the French tried to re-establish their colonial control over Vietnam, the most strategic of the three states comprising the former Indochina (Cambodia, Vietnam and Laos). Following the defeat of the French, Vietnam was partitioned by the Geneva Accords of 1954 into Communist North Vietnam and South Vietnam, which was non-Communist, but divided on religious and political lines. The United States supported a military government in the South and the decision of its leader, Ngo Dinh Diem, to prevent free elections which might result in the unification of the country under the control of the Communists. In an effort to take over South Vietnam, the Communist North supported attacks by guerrilla forces on the South. The Geneva Accords quickly began to crumble.

American foreign policy after World War II had been based on the goal of containing Communism and the assumptions of the so-called "domino theory”—that if one country fell to Communism, the surrounding countries would fall, like dominoes. The Eisenhower administration was concerned that if Vietnam fell under Communist control, other Southeast Asian and Pacific nations, including even the Philippines, would fall one by one. In response to that threat, the Southeast Asia Treaty Organization (SEATO) was formed in 1955 to prevent Communist expansion. President Eisenhower sent some 700 military personnel as well military and economic aid to the government of South Vietnam. This effort was foundering when John F. Kennedy became president.

In May 1961, JFK authorized sending an additional 500 Special Forces troops and military advisors to assist the pro Western government of South Vietnam. By the end of 1962, there were approximately 11,000 military advisors in South Vietnam; that year, 53 military personnel had been killed. The president would soon send additional military advisors to support the South Vietnamese Army. By the end of 1963, the numbers had risen to 16,000.

Materials

(All materials included in the downloadable pdf.)

  • “Historical Briefings: JFK, the Cold War, and Vietnam”
  • February 18, 1963 letter from Bobbie Lou Pendergrass to President Kennedy (also here)
  • March 6, 1963 letter from President Kennedy to Bobbie Lou Pendergrass (also here)

Procedure

  1. Have students read “Historical Briefings: JFK, the Cold War, and Vietnam” and answer the following questions:
    • What was the Cold War?
    • How and when did the Korean War begin? What forces were fighting?
    • How did the conflict in Vietnam become part of the Cold War?
    • Why did Eisenhower send military personnel to South Vietnam beginning in 1955?
    • What were the military advisors sent to South Vietnam to do?
  2. Provide students with the February 18, 1963 letter from Bobbie Lou Pendergrass to President Kennedy and his March 6, 1963 reply.
  3. Discuss the following:
    • What are Pendergrass’s main concerns about troop involvement in Vietnam? (It’s not like World War II or the Korean War: “They were wars that our country were fighting, and that everyone here knew that our sons and brothers were giving their lives for their country. Half of our country never heard of Vietnam. Our solders can’t even fight back. Is the small number of military in Vietnam sufficient to win there? What justifies the loss of life there?")
    • How does JFK respond to these concerns? (Vietnam must not fall under Communist control. If South Vietnam becomes Communist the whole region may be lost to the Communists--which would ultimately threaten our country).
  4. Put students in pairs. Using these documents as the basis for a script, have students create a phone conversation between the President and Mrs. Pendergrass in which she raises the questions she poses in her letter and he responds.
  5. Have each pair of students perform these skits for the class.

Assessment

For homework, have students write an imaginary diary entry for Mrs. Pendergrass that she might have written in which she describes her conversation and discusses to what extent she was convinced by President Kennedy’s arguments. Students may include outside research as part of this assignment.

What event led to an increase in troops in the 1960s during the Vietnam War?

In early August 1964, two U.S. destroyers stationed in the Gulf of Tonkin in Vietnam radioed that they had been fired upon by North Vietnamese forces. In response to these reported incidents, President Lyndon B. Johnson requested permission from the U.S. Congress to increase the U.S. military presence in Indochina.

Why did the United States send troops to Vietnam during the 1960s?

The USA was afraid that communism would spread to South Vietnam and then the rest of Asia. It decided to send money, supplies and military advisers to help the South Vietnamese Government.

What led to the increase in the number of US troops sent to Vietnam between 1965 and 1967?

Beginning in 1965, the United States dramatically increased its involvement in the war in Vietnam. U.S. officials and military leaders supported this "escalation" in American activity because they worried that South Vietnam's crumbling government would otherwise fall to the North Vietnamese Communists.

How did the United States increase the number of soldiers during the Vietnam War?

The Draft in Context The military draft brought the war to the American home front. During the Vietnam War era, between 1964 and 1973, the U.S. military drafted 2.2 million American men out of an eligible pool of 27 million.
