What was the Vietnam War?

The United States wanted to prevent the spread of communism through a policy referred to as containment. To do this, they fought for South Vietnam against North Vietnam who wanted to unify the country under a communist government.

It was a tough war. Soldiers dealt with high grass, booby traps and landmines, monsoon season, and chemical weapons. In the end, Americans pulled out from the country. Approximately 60,000 Americans and 2 million Vietnamese people died in the war.

Why is the Vietnam War important to know?

The Vietnam War is one of the longest wars fought by the United States. It was also the first time that the public received daily updates through broadcast radio and television.

The war was controversial and sparked lots of debate and many protests. People were angry about how and why America went to war. Many people also disagreed with the draft, which led to the all-volunteer Army that we have today.

Similarly, people didn’t like that 18-year-old men could go to war but couldn’t vote. Therefore, the 26th Amendment reduced the voting age down to 18 from 21.


November 1, 1955 – April 30, 1975


  • Ho Chi Minh – Ho Chi Minh was the nationalist leader in Vietnam. He organized people against Japan and then France. He became the leader of North Vietnam and organized the Vietnamese Communist Party.
  • Vietcong This is the name given to the Communist guerilla force in North Vietnam. They intimidated American and South Vietnamese troops.

Although he promised to withdraw troops from Vietnam, he continued to increase troops. He didn’t want to be the first U.S. President to “lose” a war.

Vietnam War APUSH Practice Question 1

During the Vietnam War, “containment” was best described as:
a. Segregating Americans of Asian descent to prevent espionage within the country.
b. Limiting the number of Communist nations throughout the world.
c. Reducing the number of people and nations involved in the Vietnam War.
d. Removing the draft and creating an army consisting of volunteers alone.

Answer: B. One of the reasons that America got involved in the Vietnam War was to prevent the North Korean Communist government from taking over the entire country. The U.S. hoped to limit the number of Communist countries since they were already involved in the Cold War with Russia.

Vietnam War APUSH Practice Question 2

The U.S. ultimately lost the Vietnam War because of all of the following EXCEPT:
a. The lack of a clear and coherent war strategy.
b. Untrained and inexperienced South Vietnamese troops.
c. Intimidating Vietcong guerrilla tactics in the high grasses.
d. Absence of the draft to recruit American troops to fight.

Answer: D. Although Americans relied on the draft at the beginning of the war, it became a point of contention. Many people looked for ways to dodge the draft, which led to an Army made of volunteers that we have today. Presumably, the reason for the U.S. loss was the lack of a war strategy, untrained South Vietnamese troops, and the intimidating Vietcong tactics.

Vietnam War APUSH Practice Question 3

President Nixon’s “Vietnamization” policy called for what?
a. Working toward a ceasefire with the North Vietnamese government.
b. Providing refuge to as many South Vietnamese people as possible.
c. Gradually removing American troops from Vietnam.
d. Training American troops to imitate the Vietcong guerrilla tactics.

Answer: C. President Nixon promised the American people that he would start to bring American troops back. Then, the South Vietnamese troops would take over. This was to be a gradual process known as “Vietnamization”. However, it turned out to be a much slower process than expected.

Vietnam War APUSH Practice Question 4

Why did Congress pass the 26th Amendment to the Constitution?
a. Because John F. Kennedy’s assassination left people confused about who should take office.
b. Since they didn’t want the right to vote tied to how much money someone paid in taxes.
c. Because people were upset that an 18-year-old man could get sent to war but couldn’t vote.
d. Since Congress wanted to show their constituents that they weren’t raising their salary unfairly.

Answer: C. With 18-year-old men drafted into the war, people questioned why they were old enough to fight but not old enough to vote. At the time, the voting age was 21. With this Amendment to the U.S. Constitution, the age was reduced to 18.

The Vietnam War created great divisions in America between the pro-war hawks and anti-war doves. As you continue to practice Vietnam War APUSH questions for the exam, think about how the war continues to impact America today.
