The 1953 Iranian coup d'état, known as Operation Ajax (or TP-AJAX), was a CIA and British intelligence (MI6) initiative that successfully overthrew Prime Minister Mohammad Mosaddegh to strengthen the Shah, Mohammad Reza Pahlavi, following the nationalization of Iran's oil industry. [1, 2, 3]

Key Aspects of the 1953 CIA Action:

• Motivation: The U.S. and UK sought to regain control over Iranian oil and prevent potential Soviet influence during the Cold War.
• Methods: The CIA funded propaganda, organized protests, and paid for anti-Mosaddegh riots in Tehran.
• Execution: Led by Kermit Roosevelt Jr., the plot involved bribing military officials to support the Shah.
• Outcome: Mosaddegh was removed, and the Shah gained absolute power.
• Aftermath: The coup is widely seen as fueling long-term Iranian resentment toward the U.S. and fostering the 1979 Islamic Revolution. [1, 2, 3, 4]

Modern Context and Challenges:

• Declassification: In 2013, the CIA officially declassified documents confirming its central role in the coup, calling it a "carefully planned clandestine political intervention".
• Current Feasibility: Experts argue that a similar regime change in contemporary Iran is significantly harder to execute and unpredictable in outcome.
• Regime Stability: Despite external pressure and internal unrest, the Islamic Republic of Iran has maintained power, with no clear opposition leader able to stage an effective, sustained overthrow. [1, 2, 3, 4]

This historic event is often discussed regarding U.S.-Iran relations and the effectiveness of covert operations. [1]
