Following is the text of a statement issued to the Press to-day.
The President of the United States, the Prime Minister of the United Kingdom and the Prime Minister of Canada have issued the following statement:
1. We recognise that the application of recent scientific discoveries to the methods and practice of war has placed at the disposal of mankind means of destruction hitherto unknown against which there can be no adequate military defence and in the employment of which no single nation can in fact have a monopoly.
2. We desire to emphasise that the responsibility for devising means to ensure that the new discoveries shall be used for the benefit of mankind instead of as a means of destruction rests not on our nations alone but upon the whole civilised world.
Nevertheless, the progress that we have made in the development and use of atomic energy demands that we take an initiative in the matter, and we have accordingly met together to consider the possibility of international action:
(a) To prevent the use of atomic energy for destructive purposes;
and, (b) To promote the use of recent and future advances in scientific knowledge, particularly in the utilisation of atomic energy for peaceful and humanitarian ends.
3. We are aware that the only complete protection for the civilised world from the destructive use of scientific knowledge lies in the prevention of war. No system of safeguards that can be devised will, of itself, provide an effective guarantee against production of atomic weapons by a nation bent on aggression, particularly since the military exploitation of atomic energy depends in large part upon the same methods and processes as would be required for industrial uses. Nor can we ignore the possibility of the development of other methods or of new methods of warfare which may constitute as great a threat to civilisation as the military use of atomic energy.
4. Representing as we do the three countries which possess the knowledge essential to the use of atomic energy, we declare at the outset our willingness as a first contribution to proceed with the exchange of fundamental scientific information and the interchange of scientists and scientific literature for peaceful ends with any nation that will fully reciprocate.
5. We believe that the fruits of scientific research should be made available to all nations and that freedom of investigation and free interchange of ideas are essential to the progress of knowledge. In pursuance of this policy the basic scientific information essential to the development of atomic energy for peaceful purposes has already been made available to the world. It is our intention that all further information of this character that may become available from time to time shall be similarly treated. We trust that other nations will adopt the same policy, thereby creating an atmosphere of reciprocal confidence in which political agreement and co-operation will flourish.
6. We have considered the question of the disclosure of detailed information concerning the practical industrial application of atomic energy. The military exploitation of atomic energy depends in large part upon the same methods and processes as would be required for industrial uses. We are not convinced that the spreading of the specialised information regarding the practical application of atomic energy before it is possible to devise effective reciprocal and enforceable safeguards acceptable to all nations would contribute to a constructive solution of the problem of the atomic bomb. On the contrary, we think it might have the opposite effect. We are, however, prepared to share on a reciprocal basis with other of the United Nations detailed information concerning the practical industrial application of atomic energy just as soon as effective enforceable safeguards against its use for destructive purposes can be devised.
7. In order to attain the most effective means of entirely eliminating the use of atomic energy for destructive purposes and promoting its widest use for industrial and humanitarian purposes, we are of the opinion that at the earliest practicable date a commission should be set up under the United Nations to prepare recommendations for submission to the Organisation. The commission should be instructed to proceed with the utmost despatch and should be authorised to submit recommendations from time to time dealing with separate phases of its work. In particular, the commission should make specific proposals:
(a).For extending between all nations the exchange of basic scientific information for peaceful ends;
(b) For control of atomic energy to the extent necessary to ensure its use only for peaceful purposes;
(c) For the elimination from national armaments of atomic weapons and of all other major weapons adaptable to mass destruction; and, (d) For effective safeguards by way of inspection and other means to protect complying states against the hazards of violations and evasions.
8. The work of the commissions should proceed by separate stages, the successful completion of each of which will develop the necessary confidence of the world before the next stage is undertaken. Specifically it is considered that the commission might well devote its attention, first to the wide exchange of scientists and scientific information, and as a second stage, to the development of full knowledge concerning natural resources of war  materials.
9. Faced with the terrible realities of the application of science to destruction, every nation will realise more urgently than before the overwhelming need to maintain the rule of law among nations, and to banish the scourge of war from the earth. This can only be brought about by giving wholehearted support to the United-Nations Organisation and by consolidating and extending its authority, thus creating conditions of mutual trust in which all peoples will be free to devote themselves to the arts of peace. It is our firm resolve to work without reservation to achieve these ends.
