198. Letter From Secretary of State Rusk to Secretary of Defense McNamara 1
Your prompt and responsive reply of December 12 to my letter of November 243 concerning the DPMs on General Purpose Forces was greatly appreciated. In my earlier letter I said I would defer until later comment on the DPMs dealing with Strategic Forces and NATO. I have now completed my review of these latter memoranda.
I have no specific suggestions for changes in this year’s force decisions. I do have some thoughts on the effect of our foreign relations of projected future trends in our strategic force posture and what we say about this posture. I believe it would be more useful, however, to comment on these in terms of a study which my staff recently completed rather than on the DPMs themselves.
Several months ago I requested an assessment of the foreign policy implications of recent and projected changes in US and Soviet military forces, with particular emphasis on the strategic forces. I enclose a copy of that study.4 I would very much appreciate your comments on it.
It is clear that many of the issues raised in this study require further examination. However, I do think the study highlights the importance of what we say about our strategic posture because of the way in which these statements may be interpreted both by the Soviets and our allies. In particular I think we should try to lead discussions away from such oversimplified concepts as “superiority” or “parity.”
I am sure you agree that it is important that we carefully coordinate the statements which we make to Congress on this score as we have done in past years. To this end I have asked Phil Farley to be in touch [Page 652]with your staff on the posture statement and to focus particularly this year on the strategic forces portion of that statement as well as the review of the international situation.
With warm regards,
