OPERATION AJAX

THE CLAIM

That the United States and Britain covertly engineered the overthrow of Iran's elected prime minister to protect Western oil interests, then denied it for the better part of a century. For decades this was dismissed in Washington as Iranian grievance-mythology. The grievance, as it turns out, was footnoted.

THE THEORY, AS ITS PROPONENTS TELL IT

For sixty years the claim that Britain and the United States had overthrown Iran's elected prime minister was, in Western public discourse, an Iranian grievance rather than a fact. It is now documented in the CIA's own released history, and the theory has shifted to what the coup established rather than whether it happened.

The mechanism as proponents describe it is the part with the widest modern resonance. Mohammad Mossadegh had nationalised the Anglo-Iranian Oil Company, and the response was not primarily military. It was informational: the CIA and MI6 paid newspapers to print fabricated stories, hired crowds to riot both for and against the government to manufacture the appearance of chaos, paid clergy to denounce Mossadegh as a communist, and financed street gangs. Kermit Roosevelt Jr. ran it from a basement in Tehran on a budget that was, by the standards of regime change, trivial.

The theory extends this into a template claim: that Ajax was the proof of concept for PBSuccess in Guatemala the following year (OSA-053), for later operations across Latin America and Southeast Asia, and for a general doctrine in which purchased media and manufactured public opinion substitute for invasion. Proponents argue that the same playbook is visible in the Nayirah testimony (OSA-064) and in more recent information operations.

The consequence argument is the one that has aged hardest. Proponents hold that the 1953 coup installed a monarchy that ruled by secret police for twenty-six years, that the 1979 revolution was its direct consequence, and that the hostage crisis, the Iran–Iraq war, and half a century of hostility trace to a decision taken in Washington and London about an oil concession.

WHAT IS KNOWN

In 1951, Prime Minister Mohammad Mossadegh nationalized the Anglo-Iranian Oil Company, ending a concession that had directed the bulk of Iran's oil wealth to Britain. London responded with embargo and, when that failed, proposed removal by covert means. The Truman administration declined; the Eisenhower administration, sold partly on Cold War grounds, did not.

The joint CIA–MI6 operation, cryptonym TPAJAX, was run on the ground by Kermit Roosevelt Jr., grandson of Theodore. Its toolkit included paid propaganda, bribery of officials and street organizers, and royal decrees pressed on a reluctant Shah dismissing Mossadegh. A first attempt on August 15–16, 1953 failed and the Shah fled the country; within days a second push, amid orchestrated and opportunistic street violence, succeeded. On August 19 Mossadegh's government fell, General Fazlollah Zahedi took the premiership, and the Shah returned to rule with increasing autocracy until 1979.

Official silence held for decades. In 2000, Secretary of State Madeleine Albright publicly acknowledged that the United States "played a significant role" in the 1953 overthrow. In August 2013, on the coup's 60th anniversary, the CIA declassified documents, published through the National Security Archive, that stated plainly the coup was carried out "under CIA direction as an act of U.S. foreign policy."

EVIDENCE FOR

• The CIA's own 2013 declassified internal history, explicitly acknowledging agency direction of the coup.
• A leaked internal CIA history by Donald Wilber, published by the New York Times in 2000, detailing planning and execution.
• Kermit Roosevelt's own memoir, Countercoup (1979), the operator confessing in hardcover.
• Albright's 2000 acknowledgment and subsequent State Department historical volumes on the operation.

EVIDENCE AGAINST (THE WILDER VERSIONS)

• "The CIA did it single-handedly" overstates the case: historians note substantial Iranian agency, clerical, military, and merchant factions had their own reasons to move against Mossadegh, and the operation nearly failed outright.
• The coup does not make every subsequent Iranian event a CIA production; the 1979 revolution had causes of its own, even if 1953 is prominent among them.
• Claims that Mossadegh was a Soviet asset, part of the era's justification, were never substantiated.

ASSESSMENT

A textbook entry in the genre this office calls "conspiracy theory, pending declassification." The interval between event and admission, sixty years for the formal version, is the number to remember when evaluating open cases. The operation achieved its immediate objective and is now widely judged, including by many in the U.S. government, to have been a long-term strategic debit whose interest payments continue. Success in August; the invoice arrived in 1979.

WHAT WOULD CHANGE THE GRADE

• CONFIRMED: the CIA's internal history by Donald Wilber was declassified, and the agency formally acknowledged its role in 2013.
• Open at the margins: how decisive the foreign hand actually was. Historians including Ervand Abrahamian and Ray Takeyh disagree sharply over the weight of CIA and MI6 action against internal Iranian actors, clerical opposition and the Shah's own position.
• British records remain closed and SIS has never published its account, so one of the two services involved has still not been heard from.
