Department of State Atomic Energy Files
The British Prime Minister (Attlee) to President Truman 91
You will remember that on 6th [7th] June this year I telegraphed to you,92 urging that steps should be taken to establish full and effective co-operation in the field of atomic energy between our two countries. I have not pressed you earlier for a reply to that message because I have been mindful of your difficulties arising from the passage through Congress of United States legislation for the control of atomic energy. Now, however, your act has been passed and the Commission which is to control these matters in your country has been appointed. Moreover, it is evident that the establishment of an effective system of international control is likely at best to take some time. In the meanwhile, however, we attach the highest importance to the continuation, in an effective form, of co-operation in the field of atomic energy, both with the United States and with Canada. I feel bound, therefore, to ask you now how in your view the understanding which we reached together in Washington a year ago can best be put into effect.
