CIA Ousted Mohammad Mosaddeq While Its Analysts and Operators Clashed

By Desmond Okafor · August 9, 2026

Two appendixes remain hidden from the internal history of the 1953 coup, masking the friction between CIA operators and analysts who worked to oust Mohammad Mosaddeq.

In August 1953, the political landscape of Iran shifted on its axis. The Prime Minister, Mohammad Mosaddeq, was removed from power in a coup that restored and strengthened the rule of Mohammad Reza Pahlavi, the Shah. This was not a spontaneous uprising of the Iranian street, though it may have looked that way in the press. It was the result of Operation Boot by the British MI6 and the TP-AJAX Project by the American CIA. The impetus was straightforward: the nationalization of Iran's oil industry by Mosaddeq had threatened British interests, and the West decided the Shah was a more reliable partner.

"Zendebad, Shah!"

Much of what we know about the mechanics of this operation comes from hindsight and selective leaks. However, the National Security Archive holds a curated description of a specific internal autopsy of the event. The file's catalogue entry records a history written by the CIA History Staff in June 1998, authored by Scott A. Koch and titled “Zendebad, Shah!: The Central Intelligence Agency and the Fall of Iranian Prime Minister Mohammad Mossadeq, August 1953.”

For nearly two decades, the full scope of Koch's history remained shielded. It was not until November 2017, following a Mandatory Declassification Review request by the National Security Archive, that the agency conducted its latest reassessment of the document. This review process resulted in a version that restores many previously Secret passages. According to the archive's description, the 2017 release also restored three out of five appendixes.

The Divide in the Field

Anyone who has spent time running assets in a hostile environment knows that there is an inherent, often violent, friction between the people who collect the data and the people who analyze it. The operator is in the mud, dealing with the volatility of human nature and the unpredictability of a local contact's greed or fear. The analyst is in a windowless room, trying to synthesize that volatility into a coherent report for a policymaker who wants a certainty that does not exist in the field.

The catalogue entry for Koch's history notes that the document contains an "interesting critique" regarding this very tension. Specifically, it highlights a "lack of interaction between the agency’s operational and analytical divisions during the effort to oust Mohammad Mosaddeq."

In the trade, this gap is a liability. When the analysts are disconnected from the operators, the intelligence becomes a feedback loop of assumptions. The operators, meanwhile, may find themselves executing a plan based on a strategic analysis that ignores the tactical reality on the ground. In 1953, this disconnect was apparently visible enough to be noted by the agency's own historians forty-five years after the fact. The record suggests that the hands and the brain of the operation were not speaking the same language while they were attempting to rewrite the government of a sovereign nation.

August 1953

The public record established by historians and encyclopedic sources confirms that the coup succeeded. Mosaddeq was overthrown on August 19, and the Shah’s authority was cemented. While the objective was achieved, the internal CIA history suggests the process was flawed. The restoration of Secret passages in the 2017 review indicates that there were details about the execution of TP-AJAX that the agency felt were still sensitive even half a century later.

It is worth noting that other records exist on this subject, including telegrams from the U.S. Embassy in Iran between 1952 and 1954 and various personnel files held within the Foreign Relations of the United States (FRUS) series. There are also earlier readings from the CIA Reading Room dating back to 1980. Yet, the Koch history represents an attempt by the agency to look back at its own tradecraft with the benefit of distance.

Even with the 2017 review, the record remains incomplete. The archive's description explicitly mentions that only three of the five appendixes were restored. This leaves two entire sections of the CIA's internal history of the coup missing from the public eye. The catalogue entry does not explain why those two appendixes remain classified or what specific information they contain. It leaves us with a partial map of a completed operation, leaving the nature of the remaining redactions as the only remaining secret of the 1953 effort.
