More than 7,000 CIA, FBI, Pentagon, and National Security Council (NSC) records—now posted on a specially created US government website at the Office of the Director of National Intelligence—shed considerable light on the state of terror that existed in Argentina from 1976 to 1983, when the military held power. The detailed documents provide extensive new evidence on the infrastructure of repression, Argentina’s role in the international terrorism campaign known as Operation Condor, and most important, the fate of hundreds of desaparecidos who were kidnapped, tortured, and murdered—among them Hidalgo Solá.
