ABSTRACT
Niels Bohr's vision frames the main proposals put forward by Manhattan Project staff who sought to shape the longer-term political outcomes of their work. The post-war settlement, they believed, had to include a design for nuclear control. Of course, how the bomb was used would also affect the settlement; some spoke to that issue. The impetus to think about post-war governance of nuclear weapons—and about international control, and Soviet inclusion—was given by the distinguished Danish physicist Niels Bohr. Some agreement about the control of the use of the new active materials can be obtained in due time, any temporary advantage, however great, may be outweighed by a perpetual menace to human security. But "without a worldwide organization for the maintenance of peace, will hasten the coming of the most destructive war in history." The Zay Jeffries Report was only one sign of concern, among the Met Lab staff at Chicago, for post-war implications of their work.
