69. Memorandum from Battle to Bundy, November 171

[Facsimile Page 1]

Enclosed is a proposed text of a message from the President to Prime Minister Macmillan replying to the latter’s letter of November 16. I believe it conforms in substance to the agreement you and Dr. Seaborg reached about the nature of a reply.

[Typeset Page 196]

However, since the proposed reply is a little more forthcoming in response to some of Mr. Macmillan’s expressed concerns, you may wish to consider whether the President should review it prior to dispatch.

L.D. Battle
Executive Secretary

Draft reply to Macmillan

Dear Mr. Prime Minister:

I have read your letter of November 16. I share your sense of the gravity of a decision to conduct nuclear testing in the atmosphere. The sober picture emerging from analyses to date of more than two score Soviet tests warns us however that we may well need to strengthen our nuclear posture. It may interest you to have the criteria which I have provided my defense and atomic advisers in preparing recommendations for me:

1. Tests will be conducted in the atmosphere only if:

a. The test will provide information of substantial importance to the national defense.

b. The information needed can be obtained in no other way, with reasonable time and effort.

c. Atmospheric fall-out is minimized in all practicable ways.

d. The military need for the test outweighs the [Facsimile Page 3] general desirability of avoiding all atmospheric fall-out.

2. Each proposed atmospheric test will be submitted to the President for decision:

a. For the present, recommendations will be restricted to tests which relate importantly to weapons development and weapons effects.

b. Approval of either proof tests or systems tests can be expected only if there is a convincing demonstration of unusual need in each case.

While no decision has been made to resume atmospheric testing, and of course no specific tests have been approved, our program is being developed under these guidelines. As these studies proceed, I will be in touch with you further regarding the consultations you propose.

Because of the time and effort likely to be required in the preparation of an island test site, we are eager to get underway the necessary work. I accept your suggestions [Facsimile Page 4] concerning the reconnaissance party. [Typeset Page 198] Dr. Seaborg will approach your people to make arrangements for immediate despatch.

Dear Mr. Prime Minister:

I have read your letter of November 16th. I share your sense of the gravity of a decision to conduct nuclear testing in the atmosphere. The sober picture emerging from analyses to date of more than two score Soviet tests warns us however that we may well need to strengthen our nuclear posture.

While no decision has been made to resume atmospheric testing, and of course no specific tests have been approved, we are developing a test program and undertaking preparations to be in a position to conduct tests in the event we decide we must. As these studies proceed, I will be in touch with you promptly regarding the consultations you propose. I hope that these consultations will proceed quickly enough to permit us to reach an understanding by the end of the year, and if the idea of a meeting in Bermuda works out, that would be a good time to deal with the matter. Meanwhile, it may interest you to have the criteria which I have now provided my defense and atomic advisers to guide them in preparing for atmospheric tests and in making specific recommendations to me:

1. Tests will be conducted in the atmosphere only if:

a. The test will provide information of substantial importance to the national defense.

b. The information needed can be obtained in no other way, with reasonable time and effort.

c. Atmospheric fall-out is minimized in all practicable ways.

d. The military need for the test outweighs the general desirability of avoiding all atmospheric fallout.

Because of the time and effort likely to be required in the preparation of an island test site, we are eager to get under way the necessary work. I accept your suggestions concerning the reconnaissance party. Dr. Seaborg will approach your people to make arrangements for immediate despatch.
