THE REST IS CLASSIFIED LIVE 2026: Buy your tickets HERE on Friday 7th November at 12pm GMT.

In the latter half of the twentieth century, the CIA and its German counterpart, the BND, were listening to the encrypted messages of at least 62 countries around the world. This intelligence was then passed to allies and used to win wars, depose leaders and influence the world order.

From sharing secrets with British forces fighting in The Falklands War to monitoring Iran’s mullahs during the 1979 hostage crisis, the CIA knew almost everything going on in the corridors of power.

In the second part of their series on Crypto AG, David and Gordon unpack the recently declassified role of the CIA in some of the biggest geopolitical moments of the past seventy years.
