Operation Shamrock was a highly secretive surveillance program carried out by the National Security Agency (NSA) in the United States from 1945 to 1975. The operation involved the systematic interception and monitoring of international telegraph communications entering and leaving the United States. Shamrock was one of the most extensive surveillance operations of its time, preceding and laying the groundwork for later mass surveillance efforts like ECHELON.
Objective: The primary goal of Operation Shamrock was to gather foreign intelligence by intercepting international communications. This was ostensibly for national security purposes during the Cold War, but the program expanded to include the monitoring of communications from U.S. citizens and residents.
