169. Memorandum From Robert Linhard and Steven Steiner of the National Security Council Staff to the President’s Acting Assistant for National Security Affairs (Keel)1

SUBJECT

  • Secretary Weinberger’s Briefing on SDI

At Tab I for your approval is a meeting memo to the President for Secretary Weinberger’s briefing on early SDI deployments.

We are still trying to pin down a full hour on Wednesday2 for this presentation and the needed discussion. We feel strongly that a full hour is needed, as the new DOD plan for beginning phased SDI deployments as early as 1993 raises a number of very difficult questions: military, budgetary, political and legal.

We aired some of these problems this afternoon at the prebrief with General Abrahamson, who was unable to come up with all of [Page 580] the answers. General Abrahamson undertook to flesh out some of these issues further with his staff, to talk them through with Secretary Weinberger in the morning and to discuss them further with us. Based on this additional airing of the issues, we will submit to you by Noon tomorrow a supplementary memo for the President designed to walk him through some of the thornier issues.

RECOMMENDATION

That you forward to the President the meeting memo at Tab I.3

SECRETARY WEINBERGER’S BRIEFING ON SDI

I. PURPOSE

Secretary Weinberger wishes to present to you a relatively near term phased deployment plan on strategic defenses.

II. BACKGROUND

Secretary Weinberger now believes that in order to protect the SDI deployment options of future presidents, it is essential that you take certain key policy steps in that direction during your remaining two years in office. He will recommend that we begin to lay the groundwork now for phased deployments of increasingly effective strategic defenses, beginning with a deployment in 1993 of two layers: space-based kinetic kill vehicles designed to intercept Soviet ballistic missiles in their boost phase and a ground-based system which would intercept Soviet warheads in their late mid-course. The plan raises a number of difficult issues which need to be aired at the meeting, including: a) the military utility of these systems and the survivability of the space-based elements; b) the need for additional SDI funding, including an FY 87 supplemental; c) the necessity for an urgent enhancement of our space boost capability; and d) the need to move to the broader, legally correct, [Page 581] interpretation of the ABM Treaty within a year or two and to break out of the Treaty altogether when we begin deployments.
