Vietnam War
5 documented theories filed under this subject.
- The Green Beret Assassination SquadsThis fringe theory claimed that the U.S. military, often specifically the Green Berets or other elite special-operations forces, experimented with psychic or parapsychological methods to kill or mentally incapacitate North Vietnamese leaders at a distance. In its strongest form, the story said specially trained military “psychic assassins” could use concentration, remote influence, or mind-directed force to kill without conventional weapons. The historical basis beneath the theory is fragmented rather than direct. The Green Berets were real and already surrounded by an aura of unconventional warfare in Vietnam, and the U.S. government later did sponsor remote-viewing and parapsychology programs beginning in the 1970s. What is not supported by the documentary record is a Vietnam-era program of Green Beret psychic kill squads operating against North Vietnamese leadership.
- The Golden Triangle Drug RunThis theory claimed that the CIA, through its proprietary airline Air America and allied covert structures in Laos, helped move opium or heroin out of the Golden Triangle and that one especially dark version of the story involved narcotics being shipped in the coffins of dead American servicemen. The documentary background is mixed but substantial. Air America was a real CIA-linked airline operating in Southeast Asia, and allegations by Alfred McCoy and others tied the airline and U.S.-backed local allies to the opium trade in Laos. At the same time, the most theatrical “coffins of dead soldiers” version belongs more to later narcotics folklore and popular culture than to the strongest documentary record on Air America itself.
- The Missing in Action (MIA) Cover-upThis theory claimed that large numbers of American prisoners and missing personnel in Southeast Asia were knowingly left behind after the war and that some remained alive for years in Laos or Vietnam as laborers, bargaining assets, or even experimental subjects. In stronger versions, the theory treated official recovery efforts as deliberately constrained and argued that classified intelligence, diplomatic priorities, or wartime embarrassment prevented a full accounting. The historical record does document enormous secrecy, emotional intensity, disputed intelligence, and decades of investigation. It does not, however, support the most sweeping claims that hundreds of prisoners were knowingly abandoned in 1970 or retained on a large scale for slave labor or medical experimentation.
- The Agent Orange Genetic HarvestThis theory claimed that Agent Orange was not only an herbicide used for defoliation, but a covert genetic-tagging system designed to mark the DNA of soldiers and make their descendants trackable by the U.S. government. In its strongest form, the theory treated dioxin exposure not as toxic contamination but as a deliberate biological registry mechanism operating across generations. The historical background that made such a theory possible is real: Agent Orange exposure became one of the most enduring health controversies of the Vietnam War, and scientific and public concern about possible effects on children and later generations has remained intense. What is not supported by the documentary record is the claim that the herbicide was designed to encode or tag DNA for surveillance purposes.
- The Operation Popeye Weather ControlOperation Popeye was a real covert U.S. weather-modification program conducted during the Vietnam War. What began as rumor that the United States was seeding clouds to prolong the monsoon and damage the Ho Chi Minh Trail was later substantially confirmed by declassified records. The operation aimed to increase rainfall over selected areas of Laos, Cambodia, and Vietnam in order to impede truck movement, soften road surfaces, create landslides, and make logistics more difficult for North Vietnamese forces. Because the program was secret and publicly denied while it was underway, it became one of the clearest examples of a conspiracy allegation that later proved largely true.
