I saw Cherwell at lunch on Friday, and reminded him of the importance we attached to the tripartite pattern in atomic energy cooperation which had been pretty faithfully observed from the wartime days up to this last Bermuda meeting. We had been concerned by the narrowly bilateral language which Sir Winston Churchill had used in his speech In Parliament in December, and hoped that the United Kingdom for their part would keep our position in mind. I told him of Swlnton's conversation with the Secretary of State for External Affairs and his assurance *tt we would have an opportunity of commenting on the ; k>posed history of cooperation in the atomic energy field ifore it was published. I went a little further and said iat I thought any public record of what had froa the feglnnlng been a three-cornered association should, be Assued under the auspices and imprimatur of the three governments concerned, and not of the United States and United Kingdom alone, as one might have gathered was contemplated from Sir Winston Churchill's speech. 2. Cherwell said that he had tried to persuade the Prime Minister to omit from his speech any reference to the proposed history of Anglo-American cooperation in the atomic energy field, primarily because he thought it unwise to promise something that might not in fact be performed; he feared it might be found that it was not practicable or expedient for security or diplomatic reasons tc publish a full account of the arrangements which had governed allied cooperation in this field during the war ar.d since. If this should turn out to ba the case the governments Involved would be Inviting pressure oa themselves by promising publication of a text which had not yet been established. He said the idea of a public statement was the Prime Minister's own and went back to a conversation he had had in Washington some years ago tflth Senator Brlen McMahon, who had told him that he would never have st>onsore the rigid legislation that bsars his name if he had himself known about the secret assurances of cooperation in th© development of atomic energy which had been exchanged between th© American, United Kingdom and Canadian Governments. IU. .230 (rev. 3/52) 000422 �Document disclosed under the Access to Information Act Document divulgue en vertu de la Loi sur I'acces a I'information - 2 ~ i ' Churchill thought and still thinks that the publication of an authoritative account of these arrangements would be a helpful and perhaps Indispensable preparation for the kind of revision of the McHahon Act which will be required if really close cooperation between the partner countries in this field is to be restored. 5. Cherwell said he had shied away from th© suggestion that he and Strauss should sit down and work out a joint draft. As matters stand Strauss has undertaken to do a first draft which is to be sent to Cherwell and the United Kingdom authorities for their comments„ Cherwell agreed that lt would b© helpful and appropriate to have Canadian comments at an early stage In the drafting. He assumed that Kr. Howe would probably wish C. J. MacKensIe who has been associated with the combined arrangemsnts from the beginning, to have a look at the proposed publication from a Canadian standpoint. For his part, although he was no longer a member of the cabinet, he felt that the official history of the tripartite understandingo and arrangements should con© out under th© auspices of the three governments involved, 4. i think I should probably try to get the United Kingdom Government committed to the proposition that tha history, if and when it appears, should be Issued under the authority of the three governments. When this is firm the question of Amsrican concurrence, which should not present difficulties, could be taken up. In the meantime I do not suppose It matters very much whether Strauss's first draft goes direct to Cherwell, with a copy communicated to us for our comments, or whether it goes simultaneously to the United Kingdom and Canadian Governments. 000423 � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.
