The "Secret War" refers to the covert operations conducted by the United States during the Vietnam War in the 1960s and 1970s. This conflict involved the CIA and other military forces supporting anti-communist groups in Laos and Cambodia to disrupt the supply lines of the North Vietnamese Army. These operations included bombing campaigns, training local troops, and conducting reconnaissance missions. The goal was to prevent the spread of communism in Southeast Asia while maintaining plausible deniability about U.S. involvement. The "Secret War" remains a significant chapter in the history of American military engagement in the region.
