United Nations Atomic Energy Commission

The United Nations Atomic Energy Commission was established through an agreement among the Soviet Union, the United States, and other countries to address international control of nuclear weapons. Its formation briefly gave institutional shape to the hope that atomic energy might be managed cooperatively; the ensuing dispute over how to achieve that goal instead exposed the conflict between international oversight and national control.

Establishment and setting

In late January 1946, Oppenheimer learned that negotiations begun several months earlier had produced agreement to establish the Commission. The development came amid growing concern that national possession of the bomb could lead to rivalry and an uncontrolled arms race. Agreement to create a United Nations body offered a forum for considering the problem, but it did not settle what powers or safeguards international control would require.

The Commission’s creation was followed by a separate initiative within the United States government. President Truman appointed a special committee, chaired by Dean Acheson, to prepare a concrete proposal for international control. When Acheson said he lacked knowledge of atomic energy, his assistant Herbert Marks recommended a Board of Consultants chaired by David Lilienthal. Oppenheimer joined that board as its only physicist and became influential in shaping its discussions. The American committee and its consultants were not the Commission itself: they were developing a proposal to be presented in the wider international debate.

Competing proposals

The Acheson-Lilienthal approach envisioned an international authority with substantial responsibility for atomic development and control, rather than relying only on a promise by states not to make weapons. In the plan’s formulation, participating nations would partially renounce sovereignty in this field so an authority could exercise its functions without a legal veto blocking them. The aim was to place both the dangers and the peaceful benefits of atomic energy within an international framework.

On June 14, 1946, Bernard Baruch presented a plan to the United Nations. The Soviet Union rejected it, as Oppenheimer and others associated with the original plan had anticipated. Soviet representatives instead proposed a treaty banning the production or use of atomic weapons. Oppenheimer regarded that response as not unreasonable, while objecting to Baruch’s public display of disappointment, which he thought ignored the predictable Soviet objection to the plan’s veto provisions. The dispute thus turned not simply on whether the bomb was dangerous, but on the terms and authority of the proposed system of control.

Breakdown of the early effort

The Truman administration rejected the Soviet treaty proposal. Negotiations continued for months in a desultory fashion, but produced no agreement. The early opening created by the Commission’s establishment therefore did not become a good-faith arrangement capable of checking competition between the two major powers. The account attributes the failure to the rejection of the Soviet response and to the breakdown of negotiations, rather than to any settled international-control system emerging from the Commission.

The consequences extended well beyond the immediate talks. Oppenheimer and many of his colleagues later blamed Baruch for the missed opportunity; Acheson likewise judged that Baruch had mishandled it. Oppenheimer did not claim to know that a different course would have changed history: he acknowledged that there was no clear evidence Stalin would have accepted the proposed inspections. He nevertheless believed that acting along the lines associated with Niels Bohr might have challenged the assumption that secrecy and national advantage could secure safety.

Historical significance

The Commission’s significance in this account lies in the gap between agreement to create an international forum and agreement on what that forum should be able to do. International control required states to accept constraints on sovereign power, while the competing plans differed over the conditions and authority of those constraints. The resulting impasse left the central question unresolved: how could atomic energy be governed internationally when the governments most capable of controlling it distrusted one another?

The failed negotiations became a point of reference for later arguments about nuclear arms control. The book contrasts the lost early opportunity with the much later emergence of serious and acceptable arms-control proposals, after the Cuban missile crisis and a substantial Soviet buildup. The Commission’s establishment therefore marks both an attempt at collective governance and the beginning of a failure whose consequences, in the book’s account, accumulated through decades of nuclear competition.
