  1. What did critics of the war begin calling for as early as 1967?

    • Repeal of the Gulf of Tonkin Resolution
    • A nuclear strike on Hanoi
    • Impeachment of Johnson
    • Invasion of Cambodia
    Reveal answer

    Answer: Repeal of the Gulf of Tonkin Resolution

    Source evidence

    PDF page 843: As early as 1967, critics of the war in Vietnam had begun to call for the repeal of the Gulf of Tonkin Resolution, which gave President Johnson the authority to conduct military operations in Vietnam in defense of an ally, South Vietnam. Nixon initially opposed the repeal efforts, claiming that doing so might have consequences that reached far beyond Vietnam. Nevertheless, by 1969, he was beginning troop withdrawals from Vietnam while simultaneously looking for a “knockout blow” against the North Vietnamese. In sum, the Nixon administration was in need of an exit strategy.

  2. What did Nixon simultaneously seek while beginning troop withdrawals in 1969?

    • A peace treaty with Cambodia
    • Full surrender of South Vietnam
    • A ground invasion of China
    • A 'knockout blow' against North Vietnam
    Reveal answer

    Answer: A 'knockout blow' against North Vietnam

  3. According to a war correspondent, what emotion did the U.S. military 'liberate' in motivating soldiers?

    • Patriotism
    • Racist feelings
    • Loyalty
    • Fear
    Reveal answer

    Answer: Racist feelings

    Source evidence

    PDF page 844: Racism on the part of some U.S. soldiers and a desire to retaliate against those they perceived to be responsible for harming U.S. troops affected the conduct of the war. A war correspondent who served in Vietnam noted, “In motivating the GI to fight by appealing to his racist feelings, the United States military discovered that it had liberated an emotion over which it was to lose control.” It was not unusual for U.S. soldiers to evacuate and burn villages suspected of shielding Viet Cong fighters, both to deprive the enemy of potential support and to enact revenge for enemy brutality. Troops shot at farmers’ water buffalo for target practice. American and South Vietnamese use of napalm, a jellied gasoline that sticks to the objects it burns, was common. Originally developed to burn down structures during World War II, in Vietnam, it was directed against human beings as well, as had occurred during the Korean War.

  4. What jellied gasoline was commonly used against human beings in Vietnam?

    • Agent Orange
    • Mustard gas
    • Napalm
    • Phosgene

    • Charlie Company
    Reveal answer

    Answer: Vietnam Veterans Against the War

    Source evidence

    PDF page 844: Many U.S. soldiers disapproved of the actions of their fellow troops. Indeed, a group of Vietnam veterans formed the organization Vietnam Veterans Against the War (VVAW).

In April 1971, John Kerry, a former lieutenant in the U.S. Navy and a member of VVAW, testified before the U.S. Senate Committee on Foreign Relations about conditions in Vietnam based on his personal observations:

    PDF page 844: “I would like to talk on behalf of all those veterans and say that several months ago in Detroit we had an investigation at which over 150 honorably discharged, and many very highly decorated, veterans testified to war crimes committed in Southeast Asia. These were not isolated incidents but crimes committed on a day-to-day basis with the full awareness of officers at all levels of command. . . . They relived the absolute horror of what this country, in a sense, made them do.” “They told stories that at times they had personally raped, cut off ears, cut off heads . . . randomly shot at civilians, razed villages . . . and generally ravaged the countryside of South Vietnam in addition to the normal ravage of war and the normal and very particular ravaging which is done by the applied bombing power of this country. . . .” “We could come back to this country, we could be quiet, we could hold our silence, we could not tell what went on in Vietnam, but we feel because of what threatens this country, not the reds [Communists], but the crimes which we are committing that threaten it, that we have to speak out. —John Kerry, April 23, 1971”

  8. On what date did the My Lai massacre occur?

    • April 29, 1975
    • May 4, 1970
    • March 16, 1968
    • January 27, 1973
    Reveal answer

    Answer: March 16, 1968

    Source evidence

    PDF page 844: On March 16, 1968, men from the U.S. Army’s Twenty-Third Infantry Division committed one of the most notorious atrocities of the war. About one hundred soldiers commanded by Captain Ernest Medina were sent to destroy the village of My Lai, which was suspected of hiding Viet Cong fighters. Although there was later disagreement regarding the captain’s exact words, the platoon leaders believed the order to destroy the enemy included killing women and children. Having suffered twenty-eight casualties in the past three months, the men of Charlie Company were under severe stress and extremely apprehensive as they approached the village. Two platoons entered it, shooting randomly. A group of seventy to eighty unarmed people, including children and infants, were forced into an irrigation ditch by members of the First Platoon under the command of Lt. William L. Calley, Jr. Despite their proclamations of innocence, the villagers were shot (Figure 30.13). Houses were set on fire, and as the inhabitants tried to flee, they were killed with rifles, machine guns, and grenades. The U.S. troops were never fired upon, and one soldier later testified that he did not see any man who looked like a Viet Cong fighter.

  11. Who attempted to evacuate women and children and reported the My Lai events?

    • Daniel Ellsberg
    • John Kerry
    • Hugh Thompson
    • John Mitchell
    Reveal answer

    Answer: Hugh Thompson

    Source evidence

    PDF page 845: The precise number of civilians killed that day is unclear: The numbers range from 347 to 504. None were armed. Although not all the soldiers in My Lai took part in the killings, no one attempted to stop the massacre before the arrival by helicopter of Warrant Officer Hugh Thompson, who, along with his crew, attempted to evacuate women and children. Upon returning to his base, Thompson immediately reported the events taking place at My Lai. Shortly thereafter, Medina ordered Charlie Company to cease fire. Although Thompson’s crewmembers confirmed his account, none of the men from Charlie Company gave a report, and a cover-up began almost immediately. The army first claimed that 150 people, the majority of them Viet Cong, had been killed during a firefight with Charlie Company.

  12. Who wrote to thirty members of Congress demanding a My Lai investigation?

    • Ron Ridenhour
    • Hugh Thompson
    • John Kerry
    • Ernest Medina
    Reveal answer

    Answer: Ron Ridenhour

    Source evidence

    PDF page 845: Hearing details from friends in Charlie Company, a helicopter gunner by the name of Ron Ridenhour began to conduct his own investigation and, in April 1969, wrote to thirty members of Congress, demanding an investigation. By September 1969, the army charged Lt. Calley with premeditated murder. Many Americans were horrified at the graphic footage of the massacre; the incident confirmed their belief that the war was unjust and not being fought on behalf of the Vietnamese people. However, nearly half of the respondents to a Minnesota poll did not believe that the incident at My Lai had actually happened. U.S. soldiers could not possibly do such horrible things, they felt; they were certain that American goals in Vietnam were honorable and speculated that the antiwar movement had concocted the story to generate sympathy for the enemy.
