2. Operation CHAOS
Initiated in 1967, Operation CHAOS was a clandestine CIA program aimed at monitoring and infiltrating anti-war and protest groups within the United States during the Vietnam War era. The operation sought to uncover potential foreign influences on domestic dissent, leading to the surveillance of thousands of American citizens and organizations. The program’s existence remained secret until investigative journalist Seymour Hersh exposed it in 1974, raising significant concerns about civil liberties and the CIA’s overreach into domestic affairs.
