Going to War in
Vietnam
What created the conflict in
Vietnam and how did
America become involved?
American Involvement in Vietnam
The Cold War policy of containment
led the United States to become
increasingly involved in events in
Vietnam.
American Involvement in Vietnam (cont.)
• One of the leaders of the nationalist
movement in Vietnam for almost 30 years
was Nguyen Tat Thanh—or Ho Chi Minh.
• His proposal for an independent Vietnam
after WWI was reject by the imperial states
of Europe.
• In the 1930’s , he found the Indochinese
Communist Party to overthrow French rule.
American Involvement in Vietnam (cont.)
• In 1941, Japan seized control of the country,
and Ho Chi Minh organized a nationalist
group called the Vietminh.
• America sent aid to the Vietminh.
• (US policy which is a predecessor to
Osama Bin Laden????)
American Involvement in Vietnam (cont.)
• When Japan surrendered to the Allies in
1945, it gave up control of Indochina;
however, French troops returned to Vietnam
in 1946.
• The Vietminh fought back against the
French-dominated regime and slowly gained
control of large areas of the countryside.
• France asked the United States for help.
American Involvement in Vietnam (cont.)
• Two events convinced President Truman to
help France:
– The fall of China to communism
– The outbreak of the Korean War
American Involvement in Vietnam (cont.)
• President Eisenhower continued Truman’s
policy and defended his decision with what
became known as the domino theory—if
Vietnam fell to communism, the rest of
Southeast Asia would follow.
• Despite help from the United States,
guerrilla tactics used by the Vietminh
consistently frustrated the French.
Why Did Vietnam Matter to the United States?
American Involvement in Vietnam (cont.)
• The French defeat at Dien Bien Phu
convinced the French to make peace and
withdraw from Indochina.
• The Geneva Accords divided Vietnam along
the 17th parallel, with Ho Chi Minh and the
Vietminh in control of North Vietnam and a
pro-Western regime in control of the South.
Vietnam, 1959
American Involvement in Vietnam (cont.)
• The U.S. became the principal protector of
the new government in the South, led by a
nationalist leader named Ngo Dinh Diem.

Political pressures in the United States
led the nation to become deeply
involved in the civil war in Vietnam.
America Becomes Involved in Vietnam
(cont.)
• Ho Chi Minh and the Communists began an
armed struggle to reunify the nation after
Ngo Dinh Diem refused to hold national
elections.
• They organized a new and powerful guerrilla
army called the Vietcong.
• Eisenhower sent hundreds of military advisers
to train South Vietnam’s army, but Diem
looked increasingly to the United States to
keep South Vietnam from collapsing.
America Becomes Involved in Vietnam
(cont.)
• On taking office in 1961, President Kennedy
continued the nation’s policy of support for
South Vietnam.
• The United States urged Diem to create a
more democratic government and to
introduce reforms to help Vietnam’s
peasants.
• Diem introduced some limited reforms, but
they had little effect.
• How bad was Diem rule????
America Becomes Involved in Vietnam
(cont.)
• Several Vietnamese generals seized control
of South Vietnam in November 1963, and
executed Diem shortly thereafter.
• His overthrow made matters worse and the
United States became even more deeply
involved.
America Becomes Involved in Vietnam
(cont.)
• On August 2, 1964, President Johnson
announced that North Vietnamese torpedo
boats had fired on two American destroyers
in the Gulf of Tonkin.
• On August 7, 1964, the Senate and House
passed the Gulf of Tonkin Resolution,
authorizing the president to “take all
necessary measures … to prevent further
aggression.”
America Becomes Involved in Vietnam
(cont.)
• After the resolution was passed, the
Vietcong began to attack bases where
American advisers were stationed in South
Vietnam.

8 Americans and wounded more than 100,
American aircraft bombed North Vietnam.

Johnson firmly believed the nation had a
duty to halt communism in Vietnam.
America Becomes Involved in Vietnam
(cont.)
• In March 1965, Johnson expanded American
involvement by beginning a sustained
bombing campaign against North Vietnam.
• The same month, he ordered the first
combat troops into Vietnam.
A Bloody Stalemate
The failure of United States forces to
defeat the Vietcong and the deaths of
thousands of American soldiers led
many Americans to question the
nation’s involvement in Vietnam.
A Bloody Stalemate (cont.)
• To counter the Vietcong’s guerrilla tactics,
American troops went on “search and
destroy” missions.
• To take away the Vietcong’s ability to hide,
American forces literally destroyed the
landscape by dropping napalm and
Agent Orange.
The Vietnam War, 1965–1973
A Bloody Stalemate (cont.)
• The guerrillas, however, had no intention of
surrendering, and they were willing to accept
huge losses to achieve their goals.
• North Vietnam sent arms and supplies south by
way of a network of jungle paths known as the
Ho Chi Minh trail.
The Ho Chi Minh Trail
A Bloody Stalemate (cont.)
• One of the main reasons President Johnson
refused to order a full-scale invasion of North
Vietnam was his fear that such an attack
would bring China into the war.

hard to win.

of attrition.

Causes of the Vietnam War

fight the Japanese, who had invaded
the region.

makes it a Communist nation allied with the USSR and
China. North Vietnam begins arming guerrillas to fight
the South Vietnamese government.

that a “domino effect” might cause all
of Southeast Asia to fall to
communism if South Vietnam falls.

involvement and gains war powers
after the Gulf of Tonkin incident.

attack with aggressive air strikes.
• United States commits over
380,000 ground troops to fighting
in Vietnam by the end of 1966.
• American people question the government’s honesty
about the war, creating the so-called “credibility gap.”
• The war casualties and the unfair draft system cause
civil unrest.
Effects of the Vietnam War
• The wartime economy hurts
domestic spending for programs
such as the Great Society.
• President Nixon is elected largely
on promises to end the war and
unite a divided country.

to limit the power of the president
during wartime.
