The Baruch Plan was a proposal by the United States government, written largely by Bernard Baruch but based on the Acheson–Lilienthal Report, to the United Nations Atomic Energy Commission (UNAEC) during its first meeting in June 1946.
In the Plan, the US agreed to decommission all of its atomic weapons and transfer nuclear technology on the condition that all other countries pledged not to produce atomic weapons and agreed to an adequate system of inspection, including monitoring, policing, and sanctions.
