Vietnam was an undeniable failure for the United States government. Despite expending more than $141 billion, and 56,000 American lives, the world’s largest military superpower was unable to achieve its sole strategic objective: to prevent Vietnam from falling under communist control. Historians are deeply divided over the reasons that led to US defeat. Most attribute the loss to several factors that each played a role. This topic offers an overview of those factors, with careful consideration of the evidence that both supports and refutes each claim as a viable reason for defeat.

Details

Context

In war reliable intelligence is essential. It gives an idea of enemy troop numbers, the strength of individual strongholds, predicts the location of future attacks, and provides information on the enemy’s firepower.

The Argument

The intelligence failings fall into three broad categories. In Vietnam, the US military possessed a lack of foresight, neglected fundamental intelligence-gathering principles, and suffered from an absence of strategy and direction. On a fundamental level, US military intelligence was unable to gauge the level of communist infiltration in the South of the country. This meant the US forces had almost no idea of the size of the enemy’s forces.[1] It wasn’t until 1967 that the CIA appointed anybody to study the actual Vietcong numbers. A glaring neglection of the fundamental principles of intelligence gathering. Nowhere was the American intelligence community’s lack of foresight more obvious than in the build up to the Tet Offensive in 1968. In a report compiled following the attacks, the CIA, NSA and Joint Chiefs of Staff (JCS) admitted “few US or GVN [Government of South Vietnam] officials believed the enemy would attack during Tet”. [2] But why? There was already a precedent for the North Vietnamese forces striking an enemy on the annual Tet holiday. In 1789, Vietnamese forces attacked and defeated the Chinese army during Tet celebrations, driving them out of Vietnam.[3] Senior members of Johnson’s administration, including Secretary of Defense Robert McNamara, who were kept abreast of the latest intelligence reports from Vietnam, admitted that they were astonished that the communists possessed the military capability to mount an offensive on the scale seen at Tet. There was a significant gap between the reality on the ground in Vietnam and what the intelligence community in Washington believed. This was entirely due to intelligence failings. The entire intelligence operation lacked direction. This is best illustrated by the lack of Vietnamese speakers among the CIA officers in the field. Language and communication skills would seem like a basic pre-requisite for an effective intelligence-gathering campaign, but in 1967 there were only three CIA officers in the field with Vietnamese language skills.[1] The rest of the CIA officers based in the country relied on interpreters, who themselves were open to Vietcong infiltration.

Counter arguments

The US intelligence community used third-country interpreters (Vietnamese speakers from abroad). These were more than capable of assisting in the process of gathering intelligence, without being compromised by communist agents.[1] Also, to point to Tet as a lack of foresight is not a fair representation of the assault. General Westmoreland ordered the redeployment of combat battalions to Saigon in anticipation of the attacks. He also ordered a country-wide alert 23 hours before the largest attacks on the major cities of Southern Vietnam.[4]

Premises

The failures of the intelligence community left US and ARVN combat forces blind and uninformed of enemy numbers, movements, offensive plans, and strategy, leading to the defeat of the US in Vietnam.
