Modern electronic surveillance across the hemisphere descends from physical intelligence infrastructure built during the Cold War. In the mid-twentieth century, intelligence agencies used capital cities across Central and South America as regional staging grounds. Operation Condor established cross-border intelligence gathering agreements among military regimes in Chile, Argentina, Uruguay, and Brazil. Operatives shared carbon-copied manifests, tracked exiled dissidents across international borders, and executed extrajudicial detentions with systematic precision.
Mexico carved out an unusual role during this era. While maintaining diplomatic neutrality, the country served as an open geopolitical listening post. Soviet officers, Cuban couriers, and American station chiefs lived side by side in Mexico City neighborhoods like Polanco and Roma. The Directorate of Federal Security (DFS) maintained extensive dossiers on everyone from foreign diplomats to domestic labor leaders. Files were stored in steel cabinets at the Lecumberri prison fortress. That physical tracking machinery provided the institutional framework for modern state surveillance technology.
