[Rockingham]

I recall an interview with the late Soviet defector Vasili Mitrokhin in which he described Robert Oppenheimer as a Soviet agent, but that the claim was edited out of his published work as too provocative. Mitrokhin's typewritten notes from his reading of the KGB archives are now on deposit with Churchill College at Cambridge in Britain, with portions though still classified and unavailable even to qualified researchers.

Due to limited information and differences in spy craft and terminology between the Soviet Union and the US, the distinction between source and controlled agent can be murky and confusing. Mitrokhin's account was to the effect that Oppenheimer knowingly provided secret information about the A bomb to a man whom he knew to be a Soviet agent. That would make Oppenheimer guilty of espionage under US law, a Soviet spy in common meaning.

Thanks for relating your memory of that inteview. I do not remember reading about that in the Mitrokhin files, but if it was as you say edited out of the book I wouldn’t. I wonder if one can find the interview somwhere. I guess it was on tele, or did you read it in a magazine?
