        Learning Activities

        1. View the segment “US Involvement in Indochina” as a class or in small groups. Ask students what they learned from the clip or what surprised them from the clip. 

        2. Discuss the following questions​ ​as a class: 

        ● Briefly explain Eisenhower and Nixon’s assessments of the situation in Southeast Asia and how the Domino Theory applies. According to this theory, what role should the United States play? 

        ● Listen to Senator Kennedy’s luncheon remarks and summarize his feelings on US involvement in Vietnam. What conditions does he suggest need to be made for the United States to support South Vietnam? 

        ● Eisenhower noted in his diary that he believed no military victory was possible in Vietnam, yet why do you think he secretly sent military aid to the French to support the desperate French troops at Dien Bien Phu? 

        3. Explain to the class that despite secret American aid, the French forces were defeated at Dien Bien Phu in May 1954. President Eisenhower asked his advisors what the United States should do next. Form students into small groups to act as President Eisenhower’s advisors. Have them read the CIA document from November 1954 and summarize its main points. 

        Then have them make a recommendation on one of the following courses of action, explaining why they believe their choice is the best one: 

        ● United States should send troops to fight any aggression from the communist North Vietnam. 

        ● United States should send only military advisors into Vietnam to help enforce the Geneva Agreement. 

        ● United States should pull out of South Vietnam completely and let the South Vietnamese government defend itself. 

        4. Have each student advisory group share recommendations. 

        5. View the clip “Ngo Dinh Diem’s Rise to Power” as a class and discuss the following questions: 

        ● How did Ngo Dinh Diem assuage the doubts many Americans had about him after the French left Vietnam? Why do you think Diem’s actions impressed the Eisenhower administration? 

        ● Senator Kennedy’s speech at the Willard Hotel not only sent a ringing endorsement of Diem but also provided a strong rationale for further US involvement in South Vietnam. Which parts of his speech made this argument? 

        ● Why did the United States feel compelled to take over for the French in Indochina? 

        6. Have students formulate statements that either support or reject further American involvement in South Vietnam at this time, identifying what degree of responsibility nations have in helping foster a peaceful world order.
