Kenneth Nichols served as Director of U.S. Army Research and Development, worked on the Manhattan Project and was the Chief of the U.S. Armed Forces Special Weapons Project. He begins by discussing the impetus behind the Manhattan Project as well as the early difficulties that cropped up with regard to setting priorities and organization. He offers a personality portrait of the project Director, Gen. Leslie Groves (above all, he was abrasive), and describes his relations with the scientists involved. Oppenheimers hiring, despite security concerns, is also discussed, leading to comments about the state of relations with the Soviet Union and contemporary fears of the influence of communism. Dr. Nichols also touches on the subject of U.S. nuclear collaboration with the British and on the high level of secrecy governing the project. He goes into detail on the complexities and problems the program faced at each of its facilities, and recounts the changed attitudes of some of the scientists after the war. His view of the morality of the Hiroshima and Nagasaki bombs is that there was nothing to distinguish them from the earlier fire bombings of Japanese cities. The interview closes with discussion of the decision-making relating to deployment of the first two bombs, the construction of a third bomb, and finally the fact that he is not surprised that nuclear weapons have never been used militarily since then.
