Message to Congress on the Atomic Bomb
President Harry S Truman
Washington, DC
October 3, 1945

Almost two months have passed since the atomic bomb was used against Japan. That bomb did not win the war, but it certainly shortened the war. We know that it saved the lives of untold thousands of American and Allied soldiers who would otherwise have been killed in battle.

The discovery of the means of releasing atomic energy began a new era in the history of civilization. The scientific and industrial knowledge on which this discovery rests does not relate merely to another weapon. It may some day prove to be more revolutionary in the development of human society than the invention of the wheel, the use of metals, or the steam or internal combustion engine.

Never in history has society been confronted with a power so full of potential danger and at the same time so full of promise for the future of man and for the peace of the world. I think I express the faith of the American people when I say that we can use the knowledge we have won not for the devastation of war but for the future welfare of humanity.

To accomplish the objective we must proceed along two fronts -- the domestic and the international.

The first and most urgent step is the determination of our domestic policy for the control, use and development of atomic energy within the United States.

We cannot postpone decisions in this field. The enormous investment which we made to produce the bomb has given us the two vast industrial plants in Washington and Tennessee, the many associated works throughout the country. It has brought together a vast organization of scientists, executives, industrial engineers and skilled workers -- a national asset of inestimable value.

The powers which the Congress wisely gave to the Government to wage war were adequate to permit the creation and development of this enterprise as a war project. Now that our enemies have surrendered, we should take immediate action to provide for the future use of this huge investment in brains and plant.

I am informed that many of the people on whom depend the continued successful operation of the plants and the further development of atomic knowledge are getting ready to return to their normal pursuits. In many cases these people are considering leaving the project largely because of uncertainty concerning future national policy in this field. Prompt action to establish national policy will go a long way toward keeping a strong organization intact.

It is equally necessary to direct future research and to establish control of the basic raw materials essential to the development of this power whether it is to be used for purposes of peace or war. Atomic force in ignorant or evil hands could inflict untold disaster upon the nation and the world. Society cannot hope even to protect itself -- much less to realize the benefits of the discovery -- unless prompt action is taken to guard against the hazards of misuse.

I therefore urge, as a first measure in a program of utilizing our knowledge for the benefit of society, that the Congress enact legislation to fix a policy with respect to our existing plants, and to control all sources of atomic energy and all activities connected with its development and use in the United States.

The legislation should give jurisdiction for these purposes to an atomic energy commission with members appointed by the President with the advice and consent of the Senate.

The Congress should lay down the basic principles for all the activities of the commission, the objectives of which should be the promotion of the national welfare, securing the national defense, safeguarding world peace and the acquisition of further knowledge concerning atomic energy.

The people of the United States know that the overwhelming power we have developed in this war is due in large measure to American science and American industry, consisting of management and labor. We believe that our science and industry owe their strength to the spirit of free inquiry and the spirit of free enterprise that characterize our country.

The commission, therefore, in carrying out its functions should interfere as little as possible with private research and private enterprise, and should use as much as possible existing institutions and agencies. The observance of this policy is our best guarantee of maintaining the pre-eminence in science and industry upon which our national well-being depends.

All land and mineral deposits owned by the United States which constitute sources of atomic energy, and all stock piles of materials from which such energy may be derived, and all plants or other property of the United States connected with its development and use should be transferred to the supervision and control of the commission.

The commission should be authorized to acquire at a fair price, by purchase or by condemnation, any minerals or other materials from which the sources of atomic energy can be derived, and also any land containing such minerals or materials, which are not already owned by the United States.

The power to purchase should include real and personal property outside the limits of the United States.

The commission should also be authorized to conduct all necessary research, experimentation, and operations for the further development and use of atomic energy for military, industrial, scientific or medical purposes. In these activities it should, of course, use existing private and public institutions and agencies to the fullest practicable extent.

Under appropriate safeguards, the commission should also be permitted to license any property available to the commission for research, development and exploitation in the field of atomic energy. Among other things, such licensing should be conditioned, of course, upon a policy of widespread distribution of peacetime products on equitable terms which will prevent monopoly.

In order to establish effective control and security, it should be declared unlawful to produce or use the substances comprising the sources of atomic energy or to import or export them except under conditions prescribed by the commission.

Finally, the commission should be authorized to establish security regulations governing the handling of all information, material and equipment under its jurisdiction. Suitable penalties should be prescribed for violating the security regulations of the commission or any of the other terms of the act.

The measures which I have suggested may seem drastic and far reaching. But the discovery with which we are dealing involves forces of nature too dangerous to fit into any of our usual concepts.

The other phase of the problem is the question of the international control and development of this newly discovered energy.

In international relations, as in domestic affairs, the release of atomic energy constitutes a new force too revolutionary to consider in the framework of old ideas. We can no longer rely on the slow progress of time to develop a program of control among nations. Civilization demands that we shall reach at the earliest possible date a satisfactory arrangement for the control of this discovery, in order that it may become a powerful and forceful influence toward the maintenance of world peace instead of an instrument of destruction.

Scientific opinion appears to be practically unanimous that the essential theoretical knowledge upon which the discovery is based is already widely known. There is also substantial agreement that foreign research can come abreast of our present theoretical knowledge in time.

The hope of civilization lies in international arrangements looking, if possible, to the renunciation of the use and development of the atomic bomb, and directing and encouraging the use of atomic energy and all future scientific information toward peaceful and humanitarian ends. The difficulties in working out such arrangements are great.

The alternative to overcoming these difficulties, however, may be a desperate armament race which might well end in disaster. Discussion of the international problem cannot be safely delayed until the United Nations Organization is functioning and in a position adequately to deal with it.

I therefore propose that these discussions will not be concerned with disclosures relating to the manufacturing processes leading to the production of the atomic bomb itself. They will constitute an effort to work out arrangements covering the terms under which international collaboration and exchange of scientific information might safely proceed.

The outcome of the discussions will be reported to the Congress as soon as possible, and any resulting agreements requiring Congressional action wild be submitted to the Congress.

But regardless of the course of discussions in the international field, I believe it is essential that legislation along the lines I have indicated be adopted as promptly as possible to insure the necessary research in, and development and control of, the production and use of atomic energy.
