CIA Santiago Station Coordination with Chilean Military Pre-1973 Coup

SUMMARY

The role of the United States, particularly the CIA, in the 1973 Chilean military coup that overthrew President Salvador Allende remains a subject of ongoing declassification and historical scrutiny. Documented CIA operations, such as Project FUBELT, aimed to undermine Allende's government and promote a military coup starting in 1970 [2, 8]. Recent declassifications in 2023 by the State Department and CIA have shed additional light on the events surrounding the coup [5].

On the day of the coup, September 11, 1973, the CIA briefed President Nixon on the Chilean military's determination to 'restore political and economic order,' noting a potential lack of a 'coordinated plan' [1]. While evidence indicates the CIA maintained contacts with Chilean military and Carabinero officials in the lead-up to the coup, the specific extent and nature of direct communication and coordination in the immediate weeks prior to September 11, 1973, is still contested and subject to further declassification [3, 7]. Many documents remain classified, limiting a full understanding of the US role [7].

STRONGEST CASE FOR

The CIA had a long-standing objective to prevent and then undermine Salvador Allende's socialist government, as evidenced by Project FUBELT [2, 8]. The agency's sustained contacts with key Chilean military figures, including a significant number of contacts between October 5 and October 20, 1970 [3], demonstrates a clear intent and infrastructure to influence the Chilean military. While the declassified PDB from September 11, 1973, suggested the military 'may still lack an effectively coordinated plan' [1], this does not preclude prior CIA efforts to encourage and facilitate the coup. The phrasing could be interpreted as a tactical assessment rather than a denial of previous coordination. Given the known history of covert operations [10], it is plausible that direct communication and coordination with coup plotters would be among the most sensitive information, thus remaining heavily redacted or classified to this day [7].

STRONGEST CASE AGAINST

While the CIA clearly engaged in efforts to destabilize Allende's government, particularly through Project FUBELT in 1970 [2, 8], the specific evidence for direct coordination in the immediate weeks leading up to the September 11, 1973 coup is not definitively established by currently declassified documents. The President's Daily Brief from the day of the coup explicitly stated that the Chilean military 'may still lack an effectively coordinated plan' [1], suggesting a lack of direct, successful coordination by the CIA with the coup leaders up to that point. The contacts mentioned in 1970 [3] occurred three years prior to the coup, and do not necessarily demonstrate continued or increased coordination immediately before the 1973 event. The ongoing process of declassification [5, 7] indicates that a complete picture has not yet emerged, and absence of evidence of direct coordination in the final weeks should not be interpreted as definitive proof of its existence.
