Oppenheimer

Testimony in the Matter of J. Robert Oppenheimer by General Leslie R. Groves, Hans Bethe, George F. Kennan, Isador Rabi, Edward Teller

Q. [...] Do you or do you not believe that Dr. Oppenheimer is a security risk?

A. In a great number of cases I have seen Dr. Oppenheimer act-I under-stood that Dr. Oppenheimer acted in a way which for me was exceedingly hard to understand. I thoroughly disagreed with him in numerous issues and his actions frankly appeared to me confused and complicated. To this extent I feel that I would like to see the vital interests of this country in hands which I understand better, and therefore trust more.

In this very limited sense I would like to express a feeling that I would feel personally more secure if public matters would rest in other hands. Edward Teller
