CIA Secret War in Laos: Project 404 and the Hmong Secret Army

SUMMARY

The 'Secret War' in Laos refers to the CIA-led covert operations during the Laotian Civil War (1960-1975), coinciding with the Vietnam War, which included extensive air support and the organization of indigenous forces. Declassified documents and historical accounts confirm the Central Intelligence Agency (CIA) recruited, trained, and paid Special Guerrilla Units, primarily Hmong tribesmen, to fight against the Pathet Lao and North Vietnamese forces. Project 404 was a specific United States Air Force (USAF) advisory mission, undertaken in conjunction with the CIA, to provide covert air support and train the Royal Laotian Air Force. The primary objectives of these operations included interdicting the Ho Chi Minh Trail and supporting anti-communist forces in Laos.

STRONGEST CASE FOR

The strongest argument for the existence and nature of the CIA's Secret War in Laos and Project 404 relies on declassified government documents, official histories, and academic research. These sources, including CIA internal documents and Library of Congress oral histories, confirm the direct involvement of the CIA in organizing, training, and funding indigenous forces, notably the Hmong, and the USAF's covert air support role through Project 404. These operations were largely clandestine, reflecting a deliberate policy to avoid direct, overt U.S. military engagement in Laos while attempting to counter communist expansion.

STRONGEST CASE AGAINST

A potential counter-argument or alternative perspective, as seen in some public discourse, suggests that labeling the operations in Laos as 'secret' is an attempt to characterize them as inherently wrongful, rather than simply covert military action. While the involvement of the CIA and USAF through Project 404 was not widely publicized in the U.S. at the time, it was known to those directly involved and to adversaries. Some might argue that the 'secrecy' refers more to public awareness within the U.S. rather than the operational clandestinity on the ground, and that the strategic necessity for these covert actions during the Cold War was legitimate given geopolitical considerations.

The CIA was headed by petroleum industry executives, who performed illegal military operations that were not approved by congress, and then funneled their profits out of the country. Yet they still get away with hiding behind the title of "the American Government".

The allied efforts in bombing targets in Laos and Cambodia were no more secretive than the main war in Vietnam. By calling them "secret", it's an attempt to label them as wrongful deeds. It is called "Secret War" because it was conducted by the CIA and not known to the US public.
