Bertrand Goldschmidt was a French physicist, the only Frenchman to work on the Manhattan Project. He later became an international authority on nuclear policy. In this interview, he recalls his role in 1944 in informing Charles De Gaulle that a new kind of weapon is about to be created that will help end the war. Frances subsequent decision to develop its own atomic capability, he says, was a function of several considerations. Security concerns and national prestige both played a part. More specifically, he cites Frances residual national feelings towards Germany after the war, the French leaderships humiliation during the Suez crisis of 1956, and the overriding desire (of De Gaulle especially) to ensure Frances independence from the United States in this field. Dr. Goldschmidt also discusses the politics of nuclear sharing within NATO, particularly the very different relationship that developed between the U.S. and its two allies, Britain and France. In addition, the interview touches on certain moral questions relating to the creation of nuclear weapons, a development that does not trouble Dr. Goldschmidt in itself since he believes that the actions of humans in this case their determination that such weapons will not be used is what matters most.
