CIA Support to Pinochet Regime and 1973 Coup: Declassified Documents (1973-1980)

SUMMARY

This dossier examines the documented involvement of the U.S. Central Intelligence Agency (CIA) in the 1973 military coup in Chile and its subsequent support for the Augusto Pinochet regime. Declassified U.S. government documents, including those from the State Department, CIA, and National Security Council, confirm that the U.S. covertly backed the coup that overthrew democratically elected President Salvador Allende on September 11, 1973. These documents also detail the CIA's organizational support to Pinochet's secret police force, DINA, in its 'formative period' in 1974. The documentation project by the National Security Archive, known as 'The Pinochet File,' has compiled many of these records, providing insights into the covert operations and the human rights abuses that followed under Pinochet's dictatorship.

STRONGEST CASE FOR

The strongest argument for significant U.S. and CIA involvement posits that declassified documents unequivocally demonstrate active covert support for the 1973 coup and subsequent aid to the Pinochet regime. The CIA provided economic backing and on-site operational assistance prior to the coup, and later offered organizational support to entities like DINA, Pinochet's secret police, despite awareness of human rights abuses. This systematic documentation from multiple U.S. government agencies, corroborated by historical scholarship and intelligence reports, points to a deliberate policy of regime change and sustained influence.

STRONGEST CASE AGAINST

A counter-argument, while acknowledging some U.S. involvement, might suggest that the extent of direct CIA culpability in orchestrating the coup itself, or in the specific atrocities committed by the Pinochet regime, is sometimes overstated or not fully detailed in available documents. While the U.S. government "appeared to condone" the coup and provided support, the primary impetus for the overthrow of Allende and the subsequent brutal actions originated from internal Chilean military and political forces. The declassified documents, while revealing, may still contain redactions or represent a partial picture of the full chain of command and direct operational control, limiting definitive conclusions on certain aspects of direct causation for the coup itself.

The CIA allowed for popular discontent to physically come into being. Without CIA money, the marches and strike that were part of the military's calculation to launch the coup would not have happened. Without these events, it is hard to say whether the military would have acted.
