Clarke describes wartime nuclear development as a joint Anglo-American programme whose participants retained knowledge after cooperation ended. He claims that more than half the people involved at some stages were British, without identifying a stage or supporting count. He also recalls a conversation with an unnamed American official historian about whether continued cooperation could have delayed independent British weapons. In that interpretation, remaining inside the programme would have allowed American officials to encourage further research before Britain built a separate weapon. The recollection and personnel estimate remain attributed claims, rather than a documented accounting of the programme.
