Ch 17 Sec 1/2

Thursday, May 24, 2012

• Understand early American involvement in Vietnam, the Domino Theory and the Gulf of Tonkin Resolution.

• Understand why napalm and Agent Orange were used.

• What sort of fighting did the Vietcong use?

French Indochina consisted of Laos, Cambodia and Vietnam.

4

During WWII France was defeated and occupied by Germany in 1940.

Japan invaded the French colonies of Indochina where they ruled Vietnam through a puppet government.

During the war the nationalist Communist leader Ho Chi Minh formed a resistance group, the Vietminh, that fought both the

Japanese and Vichy French.

After the U.S. entered WWII, the Office of Strategic Services (later the Central Intelligence Agency), sent U.S. agents into Vietnam. These men helped to train the Vietminh and they

promised Ho Chi Minh that the United States would support his goal for Vietnamese independence after the war.

Ho Chi Minh believed that after the war the United States would support independence for Vietnam but he could not

foresee the Cold War.

After WWII Ho Chi Minh, leader of the Communist Vietnamese, believed that the U.S. would not allow

France to reoccupy to its former colony, since the OSS promised that to Minh during the war. When

French soldiers returned to reassert their authority and reclaim their colony a bitter nine year war

began that ended in a French defeat that divided Vietnam into two halves. One, the north, became

communist, while the south was under U.S. influence.

In 1945 Ho Chi Minh and the communist Viet Minh gained the good will of many Vietnamese when they provided relief during a devastating famine killed almost 2

million.

The famine was caused in large part by the Japanese who exported Vietnam’s rice to feed their troops.

In May of 1950 President Truman authorized $15 million in economic and military aid to the French, who were fighting to retain control of French

Indochina, including Vietnam. As part of the aid package, Truman also sent 35 military advisers.

American Involvement in Vietnam

• FDR/Truman-aided Vietminh against Japanese during WWII.

• Eisenhower-Supported France’s return to Vietnam to get rid of Ho Chi Minh’s Communist regime. The US paid for 75% of France’s War cost, but the French ultimately lost.

• Kennedy- Sent military advisors to support the South Vietnam’s independence.

13

The Domino Theory

Eisenhower’s speech on Vietnam

Cold War theory based on the idea that if one nation was conquered by

communists, neighboring nations were at risk, and therefore it was the United States’ obligation to prevent

that from occurring.

First proposed by President Eisenhower in 1954.

It was the foundation for the war in Vietnam as well as other Cold War

conflicts.

Domino Theory

• Eisenhower stressed that if Vietnam fell to Communism neighboring countries would soon follow like Dominoes.

• Do you think one country’s change can influence a neighboring country?

15

In July of 1954 the Geneva Accords were signed dividing Vietnam at the

17th parallel for two years until elections could be held to unify the

nation.

The north became communist while the south established an anti-

communist regime that was tied to the U.S.

16

From 1955-61 Eisenhower sent $200 million in aid and around 675 military advisers.

Eisenhower’s policy on Vietnam did not involve troops, only monetary

contributions and advisors.

President Kennedy, to avoid being accused of “losing south Vietnam” as President Truman was accused of “losing China”,

increased the number of military advisors from 800 to 16,000 and formed the Green Berets special forces.

19

The U.S. military set up schools and clinics in an attempt to win the “hearts and minds” of the South Vietnamese

people.

USS Maddox

Target of a fictional North

Vietnamese naval attack

Tonkin Gulf Incident, August 1964The official story was that North Vietnamese torpedo boats launched an "unprovoked

attack" against a U.S. destroyer on "routine patrol" in the Tonkin Gulf on August 2, 1964, and that North Vietnamese PT boats followed up with a "deliberate attack" on a pair of U.S.

ships two days later. Evidence uncovered since the event has proven that there was no attack that night, and some have suggested that this incident was an excuser to escalate

U.S. involvement in the region.

21

President Johnson signed the Gulf of Tonkin Resolution, August 7, 1964

The Gulf of Tonkin Resolution authorized President Lyndon Johnson

to "take all necessary measures to repel any armed attack against forces of the United States and to prevent

further aggression."

The resolution passed unanimously in the House, and by a margin of 82-2

in the Senate.

The Resolution allowed Johnson to wage all out war against North

Vietnam without ever securing a formal Declaration of War from

Congress.

Senator Wayne Morse opposed the

resolution

involvement in Vietnam

25

LBJ stated in the 1964 presidential campaign that he was “not going to send American boys nine or ten thousand miles away from home

to do what Asian boys ought to be doing for themselves.”

By early 1965 the communists were well on their way to victory and Johnson had to either increase U.S. involvement or see South

Vietnam defeated.

Gulf of Tonkin Resolution

• Congress passed the Gulf of Tonkin Resolution, authorizing the president to “take all necessary measures,” which effectively began the Vietnam War.

27

Neither LBJ nor the American people were willing to resort to

the kind of all-out war the United States had fought against Japan and Germany. He thought

we could win the war with massive bombing and limited

U.S. ground troops.

In Vietnam, the U.S. dropped three times the

tonnage used in all of World War II, and 12 times

the tonnage used in the Korean War.

28

Arc light Operations Arc Light was the code name for the devastating aerial raids of B-52 Strato

fortresses against enemy positions in Southeast Asia. The first B-52 Arc Light raid took place on June 18, 1965, on a suspected Vietcong

base north of Saigon. In November 1965, B-52s directly supported American ground forces for the first

time, and were used regularly for that purpose thereafter.

29

B-52 bomber munitions load of over 70,000 pounds of ordnance including bombs, mines and missiles.

30

LBJ announced in July 1965 that U.S. troops

would engage in combat.

By the end of 1965 there were 180,000 U.S.

troops in Vietnam.

This grew to 500,000 by the beginning of 1968.

A Bloody Stalemate

• The North Vietnamese had inferior fire power and depended on using the Vietcong (VC) to fight a guerilla war.

• Frustrated by the Vietcong’s ability to hide in the dense jungles, American forces began dropping napalm and Agent Orange to destroy the jungle.
