Espionage and Double Agents

While secrecy defined the Manhattan Project, it was far from impenetrable. Notorious figures like Klaus Fuchs operated as double agents, passing vital information to the Soviet Union. This covert espionage accelerated the global nuclear arms race, forever altering the balance of power. Fuchs’ actions, along with those of other infiltrators, highlighted vulnerabilities within even the most guarded operations. The presence of spies amidst scientists added a tense layer of suspicion and intrigue, shaping postwar politics and the dawn of the Cold War.
