Introduction

In the third installment of "The Spy Who Started the Cold War," hosted by Indira Varma and Raza Jaffrey, the spotlight remains on Klaus Fuchs, a pivotal figure whose espionage activities significantly influenced the geopolitical landscape post-World War II. This episode delves deep into Fuchs's involvement in the Manhattan Project, his covert operations at Britain's Harwell laboratory, and the intricate cat-and-mouse game between intelligence agencies aiming to unmask his spy network.

Klaus Fuchs and the Manhattan Project

The episode opens in September 1945 at Los Alamos, New Mexico, where Klaus Fuchs is depicted concluding his intense work on the first atomic bomb. Despite the successful deployment of atomic bombs on Japan, Fuchs's ambitions extend beyond ending the war. He engages in a clandestine meeting with his Soviet handler, Harry Gold, revealing his plans to develop the hydrogen bomb—a weapon exponentially more destructive than its predecessor.

• Notable Quote:
  • Fuchs: "The end of the war was never the goal. The Americans want total domination." [09:30]

This conversation underscores Fuchs's ideological commitment to bolstering the Soviet Union's nuclear capabilities, setting the stage for the ensuing Cold War tensions.

Uncovering the Spy Ring in Canada

Post-war, news breaks in September 1945 that a Soviet defector has exposed a communist spy ring in Canada, leading to the arrest of several individuals, including Professor Israel Halperin. Fuchs, returning to Los Alamos, scrutinizes the reports and realizes that while Halperin was an acquaintance, the broader implications hint at a more extensive Soviet infiltration.

• Notable Quote:
  • Fuchs: "They were our allies. If that was ever true." [12:00]

This realization brings Fuchs's espionage activities into sharper focus, emphasizing the perilous intersection of scientific collaboration and political espionage.

Fuchs at Harwell and MI5's Suspicion

By July 1946, Fuchs transitions to Britain, joining the Atomic Energy Research Establishment at Harwell. His seamless integration into the British nuclear program raises eyebrows within MI5, particularly with Henry Arnold, Harwell's head of security. Arnold's growing suspicion is fueled by Fuchs's meticulous nature and his overly cautious behavior, prompting him to file concerns with MI5.

• Notable Quote:
  • Henry Arnold: "Fuchs is meticulous. Professionally. So your security concerns about Klaus Fuchs are that he is too security conscious?" [20:45]

Despite Arnold's apprehensions, higher-ups within MI5, including Roger Hollis and Guy Liddell, are hesitant to act on these suspicions, valuing Fuchs's expertise over the unverified claims of his colleague.

Personal Struggles and Final Acts of Espionage

As Fuchs becomes entrenched in his role at Harwell, personal and professional pressures mount. His clandestine affair with Erna Skinner, the wife of his superior, Herbert Skinner, adds complexity to his espionage activities. This relationship not only jeopardizes his cover but also strains his ability to maintain his dual life.

• Notable Quote:
  • Fuchs (thoughts): "I did my part. I gave the Soviet Union a fighting chance. Time to go to ground." [25:50]

Fuchs's decision to cease his espionage activities signifies a turning point, reflecting the internal conflicts and external pressures that eventually lead to his downfall.

The Venona Project and MI5's Dilemma

Parallel to Fuchs's narrative, the episode introduces the Venona Project, a top-secret American initiative aimed at decrypting Soviet communications. Meredith Gardner, a Russian linguist at the US Army Signals Intelligence Service, uncovers messages that inadvertently point to Fuchs as a key Soviet asset.

• Notable Quote:
  • Colonel James Robertson: "Fuchs is the Soviet agent, or at least the one who has been passing information to the Kremlin." [27:15]

Back at MI5, Arthur Martin and Colonel Robertson grapple with the implications of these decrypted messages. The revelation that Fuchs is likely the Soviet spy within Britain's nuclear program creates a bureaucratic quagmire, as MI5 grapples with leveraging this intelligence without exposing the Venona Project's existence.

Conclusion and Legacy

The episode concludes by highlighting the precarious balance intelligence agencies must maintain between national security and operational secrecy. Fuchs's espionage not only accelerates the arms race of the Cold War but also exposes vulnerabilities within allied intelligence frameworks. His eventual exposure serves as a cautionary tale about the intricate interplay between scientific collaboration and espionage.
