3. Operation Ajax

1953 Tehran. An American diplomat called Kermit Roosevely III rides through the city’s streets on his way to see the Shah of Iran. Although he can’t see anything because he’s riding in the boot covered in a Persian carpet. He doesn’t want to be seen because he’s on a top secret mission. A mission from the American government. To overthrow Iran’s popular Prime Minister threatening to nationalise the oil industry — Mohamed Mossadegh. Kermit is organising a coup.

This is the story of how America came up with a blueprint of how to fight its communist enemies abroad while still looking like the good guy. How it maintained its role as the virtuous superpower while getting rid of people it didn’t like. They decided to do it in secret, using the ultimate invisible hand - the CIA.

It’s a tale of oil, money, power and marks the start of a toxic relationship between Iran and the US that is still playing out to this day.

David Dimbleby tells the story of how in the middle of the 20th century one country - America - became a superpower and shaped the world around it.

It began with a vision. A vision born out of the ashes of World War Two. A vision of a world shaped not by war but by peace. This vision of America at the head of the free world came to be the defining idea at the center of the past 80 years of world politics. And yet now it is under threat.

So how did we get here? How did America become the leader of the free world and why did it go wrong? It’s a story shaped by people. People you have probably never heard of.

In the 20th Century, these ‘invisible hands’ wrote the story America came to believe about itself. A story of moral leadership leading to prosperity and peace. But is it a story that has run out of steam?
