The memorandum from Dean Acheson to the president discusses the policy regarding the secrecy of scientific knowledge about the atomic bomb and atomic energy. It argues that maintaining secrecy is futile and dangerous, and the focus should be on international cooperation and controls to prevent a race towards mutual destruction. The memorandum presents several premises, including the widely known theoretical knowledge of atomic energy, the revolutionary nature of the discovery, and the inability to protect oneself once others possess the knowledge. It also emphasizes the moral and political limitations on the use of atomic weapons. The memorandum highlights the potential negative perception of joint development with the UK and Canada by the Soviet Union and the importance of avoiding an atmosphere of suspicion and hostility. It suggests that exclusionary policies hinder long-term understanding and make organized peace impossible. The memorandum emphasizes the need for agreement and collaboration between the United States, the United Kingdom, and the USSR and recommends gradually exchanging scientific information and collaborating on the development of atomic power. It proposes mutual renunciation of further destructive developments with adequate inspection for mutual confidence. The memorandum suggests extending these principles to other countries over time. It advises initiating discussions with the Soviet Union while informing the public and Congress about the reasons for collaboration and the need for immediate approaches. The memorandum recommends the President send a message to Congress outlining the reasons and requesting full consideration of atomic energy issues. It suggests reporting the outcome of negotiations to Congress and seeking necessary legislative action based on resulting agreements. The memorandum concludes that the approach to the Soviet Union should not involve substantial disclosures beyond what has already been made public.
