• The Operation Popeye Weather Control

  Operation 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.
