'Fifty Years of Silence' — NSA Publishes Comprehensive Dirty War Report

The National Security Archive publishes a comprehensive briefing book titled 'Fifty Years of Silence: Mexico Faces the Legacy of its Dirty War,' accompanying Mexico's truth commission reports covering systematic state violence from 1965 to 1990. The report examines how Mexican security forces targeted political dissidents — beginning with the 1968 student movement — and details how US officials prioritized Mexican political stability over documented human rights abuses during the Cold War. Newly analyzed US documents reveal the depth of intelligence sharing between the CIA and Mexico's DFS during the Tlatelolco era.
