After a fact-finding visit to the United States in 1942, Perrin realised that its government had, at last, recognised the significance of the atomic bomb, and saw the potential of that country now that it had properly mobilised. On arriving home he worked to persuade the government of the importance of combining with America. This was accepted; about sixty Tube Alloys scientists were sent to America in the British Mission and subsumed into the

It was Perrin who was asked to manage the damage caused by that discovery.
