Robert McNamara, et al.: “U. S. Military Victory in Vietnam: A Dangerous Illusion?”  Chapter 7 from Argument Without End: In Search of Answers to the Vietnam Tragedy

 

 

 

Overview

 

The introduction of this article was written by Robert McNamara, Secretary of State from 1961 - 1968.  Colonel Herbert Schandler, a Vietnam veteran whose doctoral studies focused on the war, wrote the text and conclusion.  McNamara asked Schandler to write a review of military policy and operations in Vietnam.  In particular, he asked Schandler the following question: Could the United States have won the war militarily at acceptable cost and risk?

 

Other questions Schandler was asked to address include: Could or should the South Vietnamese win the war themselves?  How effective were the U.S. military tactics, including the bombing campaign in the north?  How effective was the U.S. strategy of attrition?

 

   

Outline

 

 

I. The Heart of the Illusion

 

A. The illusion – The U.S. military was denied a victory because of constraints by Washington.

 

B. Reality – This was a “people’s war,” not a war of northern aggression.  It was a civil war.  The U.S. ignored the social nature of the war, which the North Vietnamese and southern allies understood well.

 

 

II. John Kennedy: Counterinsurgency – Winning Hearts and Minds

 

A. General Edward Lansdale recommended counterinsurgency measures to meet the guerilla threat (“southern insurgency”) in January 1961.  These measures were approved by Kennedy. The core of the strategy was that the South Vietnamese eventually had to defend itself and stand on its own.

 

B. The strategic hamlet program was designed to develop support among the rural populations for the Saigon government.  Instead, the villagers viewed the hamlets as another program by the corrupt Saigon government.  This, in turn, made it easier for the communists and Vietcong to infiltrate the countryside.

 

C. The South Vietnamese army was ineffective – Saigon leadership was unable to win loyalty of South Vietnamese people and, therefore, its survival depended on U.S. military, political and economic support

 

 

III. Lyndon Johnson:  “Everything necessary….only what is absolutely necessary…”

 

A. Saigon’s poor performance led to more communist advances;    ARVN military demoralization in countryside

 

B. Tonkin Gulf incident in August 1964 led to first U.S. reprisal with congressional resolution of support ; Established precedent for direct U.S. military action against the North.

 

C. Joint Chiefs of Staff recommended air strikes in the North and, specifically, the Ho Chi Minh Trail; Johnson concerned about North Vietnamese retaliation and ability of south to withstand the retaliation

 

D. Missed opportunity to fundamentally reassess the American commitment to the fatally flawed government in South Vietnam

 

 

IV. The Air War: The Futile Effort to Break Hanoi’s Will

 

A. In February 1965, NLF raids against U.S. advisers’ barracks and an American helicopter base near Pleiku prompted the air strikes – transformed the war into a U.S. war against North Vietnam and its southern allies.

 

B. Air strikes from 1965 – 1967:

i. Limited bombing with weekly targets was approved

ii. Concern about Chinese and Soviet response

iii. Joint Chiefs opposed to gradual and limited bombing campaign, but World War II tactics ineffective in Vietnam because of limited targets

iv. Repeated requests by Joint Chiefs to lift bombing restrictions even though U.S. intelligence revealed that airpower would be ineffective

v. North Vietnam’s adaptability and resourcefulness were greatly underestimated – no long-term impact on supply lines

 


C. Reasons for failure:

i.   Agricultural country with few industrial targets – minimal impact on economy

·       North Vietnam’s armed forces placed little reliance on the domestic economy for war material (other than manpower)

ii.     Supply needs did not match conventional war criteria used to justify the bombings

iii. Blind faith in bombings ignored the true nature of the war – a revolutionary conflict, not a struggle between industrialized powers

iv. Hanoi leaders had prepared its citizens for bombings – oil and other commodities were dispersed, school children had foxholes under their desks, bomb shelters everywhere

v. Aid from socialist countries

 vi. Hanoi government was effective in using the bombings to mobilize people behind the communist war effort.

 

  V. The Ground War: The U.S. Strategy of Attrition

 

A. US Marines landed at Da Nang in March 1965 – first time that an organized ground unit had been committed

 

B. Johnson approved additional forces in April 1965 – marked the president’s acceptance of concept that U.S. ground forces could engage in ground operations

·       Defensive strategy was inconsistent with military training

 

C. General Westmoreland presented offensive plan with three phases and was given authority in June 1965 to commit U.S. ground forces anywhere to strengthen South Vietnamese forces – liberated from restrictions of defensive mission

·       Phase 1 – 175,000 troops (Johnson approved)

·       Phase 2 – additional 100,000 troops (decision deferred)

·       Phase 3 – unspecified additional reinforcements (decision deferred)

·       Authority to call up 235,000 reservists (Johnson refused)

 

VI. End of the illusion of victory in Vietnam

 

A. Strategy of attrition failed because the North Vietnamese were willing to take casualties at an alarming rate without giving up the fight – 300 U.S. troops lost in Ia Drang as compared to 1,300 North Vietnamese

 

B. Tet Offensive in January 1968 exposed the illusion of military victory:

i. U.S. and South Vietnamese didn’t believe the action would come during Tet

ii.     U.S. command failed to anticipate the scope and intensity of the NLF attacks

 

C. Joint Chiefs saw opportunity to finally obtain the number of troops they thought necessary to achieve their military victory, however....

 

D. Johnson announces in March 1968:

i.     Only token increase in American forces

ii.    Expansion and improvement of South Vietnamese forces is first priority

iii.     Halt bombing north of 20th parallel

iv.    Would not accept nomination for another term as president

 

E. Johnson’s speech brought U.S. commitment and strategy in Vietnam into line with political objectives and constraints, which had been misunderstood and resented by his military advisors – end of the illusion of victory in Vietnam

 

F. Johnson’s speech also put the South Vietnamese government on notice that U.S. aid could not be taken for granted

 

 

  Discussion questions

 

1. How did the shortcomings of the South Vietnamese government impact the U.S. political and military strategy?

 

2. Why were the North Vietnamese leaders more effective in gaining the support of the South Vietnamese people?

 

3. Were U.S. concerns about Soviet and Chinese retaliation exaggerated?
