📖 What Led to This
Operation Ajax (1953) was the CIA's first successful regime change — and one of the most consequential covert operations in history. When Iran's democratically elected Prime Minister Mohammad Mosaddegh nationalized the Anglo-Iranian Oil Company (now BP) to keep Iranian oil profits in Iran, Britain and America responded by destroying Iranian democracy.
The operation was remarkably simple: CIA agent Kermit Roosevelt Jr. (grandson of Theodore) spent about $1 million bribing Iranian military officers, religious leaders, and street thugs to create chaos. Staged protests, planted newspaper stories, and paid mobs created the appearance of a popular uprising against Mosaddegh. On August 19, 1953, the military arrested Mosaddegh and restored the authoritarian Shah Mohammad Reza Pahlavi to full power.
The Shah ruled as a brutal dictator for 26 years, with his SAVAK secret police (trained by the CIA and Mossad) torturing and killing thousands of dissidents. When Iranians finally overthrew the Shah in 1979, they directed their fury at the country that had imposed him — taking 52 American hostages for 444 days and establishing an Islamic Republic that remains America's primary adversary in the Middle East.
The $11 million spent on Operation Ajax may be the most destructive investment in American history. The 1979 hostage crisis destroyed Jimmy Carter's presidency, led to U.S. support for Saddam Hussein's Iraq in the Iran-Iraq War, contributed to the rise of Islamic fundamentalism, and created the adversarial U.S.-Iran relationship that continues to produce crises today — including the 2026 strikes.
The libertarian lesson is devastating: a covert operation to protect corporate oil profits destroyed a democracy, installed a dictator, produced blowback that has cost trillions of dollars and thousands of lives, and the consequences are still unfolding seven decades later.
“If you sit in a country long enough, you get used to it. The people who overthrew Mosaddegh were the people who had always run things.”

💡 Did You Know?
- •The entire operation cost roughly $1 million ($11 million adjusted) — making it perhaps the highest 'return on investment' for destruction in U.S. intelligence history.
- •Mosaddegh was TIME Magazine's Man of the Year in 1951 — a democratically elected leader who was overthrown because he tried to keep Iran's oil profits in Iran.
- •The CIA didn't acknowledge its role in the coup until 2013, when it released classified documents — 60 years after the fact.
- •Kermit Roosevelt Jr., the operation's leader, was the grandson of President Theodore Roosevelt. After the coup, he left the CIA and became an oil company consultant.
- •The Shah's SAVAK secret police, trained by the CIA and Israeli Mossad, tortured an estimated 3,000-5,000 political prisoners — creating the conditions for the 1979 Islamic Revolution.
- •President Eisenhower initially opposed the coup but was convinced by the British (who were furious about oil nationalization) and by Cold War fears that Mosaddegh might align with the Soviets.

⚡ Controversies
The coup overthrew a democratically elected government to protect British oil profits, dressed up in Cold War anti-communist rhetoric — Mosaddegh was not a communist.
The CIA didn't acknowledge its role until 2013, maintaining six decades of lies about American involvement in destroying Iranian democracy.
The operation's 'success' created a template for CIA regime change that was repeated globally, producing disasters in Guatemala, Congo, Chile, and elsewhere.
The Shah's subsequent 26-year dictatorship, enabled by U.S. support and CIA training of his secret police, created the conditions for anti-American Islamic fundamentalism.
🏛️ Legacy & Impact
Destroyed Iranian democracy and installed a brutal dictatorship that lasted 26 years. Created the conditions for the 1979 Islamic Revolution, the hostage crisis, and the adversarial U.S.-Iran relationship that persists today. Demonstrated that covert regime change produces catastrophic long-term blowback. Established the CIA's regime-change playbook that would be used in Guatemala (1954), Congo (1961), Chile (1973), and beyond. Iran's democratic traditions were set back by decades.
🗽 The Libertarian Case
The original sin of US Middle East policy. Overthrowing Iran's democracy for oil profits created the chain of events leading to the Islamic Revolution, the hostage crisis, and decades of conflict. The blowback is still shaping world events 70 years later.
