74. Memorandum From the President’s Assistant for National Security Affairs (McFarlane) to President Reagan1

SUBJECT

  • Background Material for the NSPG Meeting, Friday, October 11, on ABM Treaty Interpretations

The NSPG today will focus on the question of whether or not the US should adopt a broader interpretation of the restrictions on non-traditional ABM systems (like those at the heart of SDI) posed by the Anti-ballistic Missile (ABM) Treaty. The short issue paper at Tab A describes two alternative options available. Legal opinions from the [Page 250] General Counsels of State, OSD and ACDA are highlighted at Tab B,2 for your background.

One alternative is a narrower interpretation of the Treaty which has been generally asserted by the US since the Treaty’s ratification. This interpretation, which we hold today, would permit research, but restrict some large scale testing and prohibit development of many SDI systems based on newer technologies under the Treaty. This interpretation would not inhibit us from pursuing our SDI research as currently planned for a number of years, albeit at some price in terms of additional program cost, time and increased uncertainty. On the other hand, it does impose restrictions that we will have to face at some point if the research is successful. There is little evidence that the Soviets have ever agreed to this interpretation—although they may wish to grasp it now in an effort to block SDI. The Congress and our allies are familiar with this interpretation, and any change from it will surely cause problems with which we will have to deal.

The other alternative is a broader, and somewhat more literal interpretation of the Treaty text. If adopted, it would permit us to go beyond research to testing and development (but not deployment) of defensive systems based on new technologies. The benefits to increased flexibility in pursuing the SDI program are clear and it is more consistent with your stated view of your intent with respect to the SDI program. On the other hand, should we move in this direction, even if handled well, it is very likely that certain elements of Congress will react strongly and attempt to place legislative restrictions on our freedom of action, attacking SDI funding or strategic force modernization funding in retaliation. We should also expect that some allies will make an issue of this.

Timing is important if we are to accept a new, more broad interpretation. Should we move towards a broader interpretation at this time, we will face handling the likely objections of members of Congress during the appropriation cycle. We may also face a debate in the alliance on this issue just prior to the Geneva meeting. The Soviets will attempt to feed this debate to drive wedges where possible. On the other hand, there will never be a good time to step up to this. There is merit in the argument that if we are to shift to a broader interpretation, we should do it well before the research program demands that we do. And since, unfortunately, the issue is already in the press, we may never recover the opportunity to shift to this broader interpretation if we fail to seize this moment.

[Page 251]

The long and short of this is that I feel that there is sufficient ambiguity in the Treaty and the negotiating record to support the broader interpretation should you choose to pursue it. This does not mean that there will not be some legal challenges made, but that there are sufficient grounds to legally fight these challenges. At the NSPG I will go through the articles of the Treaty and explain how the broader interpretation could be presented.

The critical issue that you must decide is whether this broader interpretation is necessary to achieve the goals you have set for the program under the ABM Treaty, and if so, if now is the time to take this step.

I believe that there is general consensus at the senior levels of the Administration that the legal case for the broader interpretation exists and that, if supportable, it would put us in a much better position to pursue the SDI research. I also believe that this interpretation is fundamentally more consistent with your views of the program. However, the broader interpretation is not necessarily needed now to permit the research we plan (and likely not needed for a few years at least). It is on this last issue that my recommendation hinges most importantly because it is very unclear whether we can sustain the needed support for the SDI program were we to publicly adopt this new interpretation now.

My recommendation is contained in the Draft NSDD at Tab C3 and essentially makes moot the issue of which interpretation is chosen. The program has been charted to provide the answers we need under the current, more restrictive interpretation. The talking points I intend to use in setting the stage for your decision on this issue are at Tab II for your information. Also, provided are proposed talking points for your use (Tab III).

INTERPRETING THE ABM TREATY RESTRICTIONS

Issue: How should the U.S. interpret the ABM Treaty’s restrictions on systems based on “other physical principles” (i.e., systems other [Page 252] than traditional ABM interceptor missiles, launchers and radars)? Should the USG interpret the Treaty as applying the prohibition on “the development, testing and deployment of sea-based, air-based, space based or mobile land-based ABM systems and components” to systems based on “other physical principles” as well as those on which ABM systems were based at the time the ABM Treaty was signed?

Introduction: Since 1972, a variety of U.S. officials have publicly and privately maintained that Article V of the ABM Treaty prohibits development, testing and deployment—but not research on—ABM systems and components that are not fixed, land-based and regardless of whether they are based on new or older technologies or principles. It is not clear that the Soviets shared this view when the Treaty was signed.

Recent study of the Treaty and the negotiating record suggest that a broader interpretation (more literal) of the Treaty is appropriate. This interpretation maintains that the Treaty permits research, testing and development (but not deployment) of non-fixed ABM systems or components which are based on other physical principles.

The central choice is whether we should move to this broader interpretation at this time.

This paper addresses the generally accepted Treaty terminology, the two interpretations and their supporting rationale. Relevant ABM Treaty provisions are attached for your reference.

ABM Treaty Terminology

The ABM Treaty provisions regarding “components” can be most clearly understood by considering the three categories of ABM systems contemplated by the Treaty.

a)
Current” systems. These are systems consisting of fixed, land-based components that composed the “current” systems at the time the Treaty was negotiated. Article II defines such components as ABM interceptor missiles, ABM launchers and ABM radars. The deployment of such components is limited to locations and numbers specified in Article III and such components may be tested in conformity with Article IV.
b)
Article V systems. Article V deals with ABM systems and components that are mobile land-based, sea-based, air-based, and space-based. Such components would include ABM interceptor missiles, ABM launchers and ABM radars as defined by Article II and devices capable of substituting for one or more of such ABM components. Article V, paragraph 1 provides that such systems or components may not be developed, tested or deployed; research on such systems or components is not prohibited.
c)
ABM systems based on “other physical principles” addressed in Agreed Statement D. These are ABM systems with components based upon physical principles other than those used in ABM systems “current” at the time the Treaty was negotiated. These would be devices capable of substituting for ABM interceptor missiles, ABM launchers or ABM radars. Articles III and IV and Agreed Statement D allow the research, development and testing of such fixed, land-based components, but prohibit their deployment absent prior discussion pursuant to Article XIII and agreement to amend the Treaty in accordance with Article XIV.

Narrower Interpretation

Under the interpretation generally held since 1972, with the above terminology as background, the ABM Treaty prohibits the development, testing, and deployment of sea-based, air-based, space-based, and mobile land-based ABM systems and components based on physical principles other than those on which ABM systems were based at the time of signature of the ABM Treaty (as well as ABM systems and components based on then-current technology).

This interpretation is supported by the following argumentation:

Article II of the ABM Treaty defines an ABM system as a “system to counter strategic ballistic missiles or their elements in flight trajectory.” It states that ABM systems “currently consist of” ABM interceptor missiles, ABM launchers and ABM radars. Thus, Article II indicates that there could be other types of ABM systems or components developed in the future.
Article III of the Treaty prohibits the deployment of ABM systems except that fixed land-based ABM systems utilizing technology current in 1972 can be deployed at specific sites under specific limitations.
Article V, paragraph 1, prohibits the development, testing and deployment of other than fixed land-based ABM systems. Like Article III, Article V is all encompassing. Article II makes clear that Article III and Article V apply to all types of ABM systems regardless of the technology utilized.
In agreeing to the language of Article V, 1. the U.S. and Soviet negotiators also agreed that the text covers “any type of present and future components.” Thus, the development, testing and deployment of other than fixed land-based ABM systems or components based on other physical principles is prohibited by Article V, 1.
Agreed Statement D is by its terms associated with Article III and provides that should types of ABM systems appear in the future based on other physical principles, they cannot be deployed at these [Page 254] permitted sites without amendment of the Treaty—otherwise the balance established by Article III would be upset.

Broader Interpretation The alternative, broader interpretation holds that the ordinary meaning of Agreed Statement D is that “specific limitations” on ABM systems “based on other physical principles” will be “subject to discussion.” Moreover, by implication, the Treaty—apart from Agreed Statement D—does not provide “specific limitations” on sea-based, air-based, space-based or mobile land-based systems, based on physical principles other than those current at the time the Treaty was signed.

This broader interpretation is supported by the following argumentation:

The use of the phrase “currently consisting of” in Article II can be read to mean that all future variants of existing ABM systems and components are covered by the Treaty.
In that case, Article V would prohibit testing, development, and deployment of all mobile systems using new technologies.
On the other hand, if Articles II and V had this effect, there would not be a need for the undertaking in Agreed Statement D to discuss “specific limitations” on future ABM systems “based on other physical principles.”
The fact that “specific limitations” on future systems remain “subject to discussion” indicates that the Treaty by itself does not limit these systems.
Furthermore, the text of Agreed Statement D is unclear as to what rules, if any, apply before the Parties reach agreement on “specific limitations” and amend the Treaty accordingly.
The ambiguity should be resolved by looking at the negotiating record, not at subsequent unilateral statements by U.S. officials. The negotiating record contains conflicting evidence, but the dominant evidence is that the Soviets never committed themselves to limitations on future systems.

PROPOSED TALKING POINTS

INTRODUCTION

— Mr. President in the past two weeks you have received briefings on our own SDI research program and, more recently, on the considerable effort that the Soviet Union has made in the area of strategic defense. Both of these perspectives have been accompanied by an underlying set of constraints which derive directly from the ABM Treaty.

— Today, I would like to provide an overview of the various provisions of the ABM Treaty. As you know, the SDI program, from its inception, has been designed to be fully in compliance with the provisions of the Treaty.

— At the conclusion of my overview I will provide you with a staff interpretation, and rationale therefore, which addresses the Treaty’s limitations on research, testing, development and deployment of ABM systems or components based on other physical principles—that is—based on technology which was not current in 1979 when the Treaty was signed.

— This interpretation has been long overlooked, and it probably would never have come to light if we hadn’t honestly been searching [Page 257] for the boundaries of the Treaty, within the context of the newly emerging technologies of SDI.

OVERVIEW OF TREATY TEXT

— The overview will be in order by Treaty articles, so you may want to follow along with the texts in your red folders (Tab A).

Article I of the ABM Treaty of 1972 states its central purpose—to prohibit deployment of “ABM systems” which are defined in Article II, except for certain deployments specifically permitted by Article III, or deployments otherwise agreed upon in accordance with provisions for ongoing review and amendment of the Treaty. Thus, Article I(2) states:

Each Party undertakes not to deploy ABM systems . . . except as provided for in Article III of this Treaty.

Article II defines the terms “ABM system” and ABM “component.” These terms are the subject of limitations set forth in other provisions of the Treaty. Under Article II(1):

  • an ABM system is a system to counter strategic ballistic missiles or their elements in flight trajectory, currently consisting of:
    (a)
    ABM interceptor missiles . . .;
    (b)
    ABM launchers . . .; and
    (c)
    ABM radars. . . .

— Paragraph 2 of Article II identifies the listed elements—ABM interceptor missiles, ABM launchers, and ABM radars—as “ABM system components.”

Article III of the Treaty specifies the permitted deployments of ABM systems, consisting of two complexes, one to defend a “Party’s national capital” and the other to defend an area containing “ICBM silo launchers.” A 1974 Protocol reduced the number of permitted complexes from two to one for each Party at their choosing. In pertinent part, Article III states that:

Each Party undertakes not to deploy ABM systems or their components except that: . . .within one ABM system deployment area having a radius of one hundred and fifty kilometers . . ., a Party may deploy: (1) no more than one hundred ABM launchers and no more than one hundred ABM interceptor missiles at launch sites, and (2) ABM radars [with specified limits on the number and characteristics of these radars].

— Other provisions of the Treaty allow upgrading of these permitted ABM systems, subject to certain restrictions: “modernization and replacement of ABM systems or their components may be carried out” (Article VII), except that “Each Party undertakes not to develop, test, or deploy ABM launchers for launching more than one ABM interceptor [Page 258] missile at a time from each launcher . . . or semiautomatic or other systems for rapid reload of ABM launchers” (Article V(2)).

— Parenthetically I would only note that the Soviet Union has constructed and continuously upgraded an ABM defense of Moscow and has violated the restrictions on radars by construction of a large, phased-array radar at Krasnoyarsk. Meanwhile, the United States in 1975 deactivated its only deployed ABM systems at Grand Forks, North Dakota.

Article IV clarifies that the Article III limitations on deployment do not “apply to ABM systems or their components used for development or testing, and located within current or additionally agreed test ranges.”

— Article V(1) of the Treaty provides that:

Each Party undertakes not to develop, test, or deploy ABM systems or components which are sea-based, air-based, space-based, or mobile land-based.

Article V prohibits development, testing and deployment of mobile systems. I will be returning to the issue of whether this provision applies to only the systems or components current when the Treaty was signed or also applies to the creation of new systems or components based on other physical principles. In either case, Article V restricts permitted deployments of ABM interceptor missiles, launchers and radars under Article III to fixed, land-based systems.

Article VI deals with prohibitions on giving non-ABM missiles, launchers and radars capabilities of ABM components and places restrictions on future early warning radars.

Articles VIII through XII of the Treaty deal with matters of implementation and compliance, including dismantlement of deployed ABM systems “in excess of the numbers or outside the areas specified in this Treaty” (Article VIII), a prohibition on “transfer to other States” and deployment of ABM systems “outside the national territory” of the Parties (Article IX), agreement “not to assume any international obligations which would conflict” with the Treaty (Article X), and agreement to “continue active negotiations for limitations on strategic offensive arms” (Article XI).

Article XII provides that, to monitor Treaty compliance, “each Party shall use national technical means of verification.” Further, under Article XII, “Each Party undertakes not to interfere with the national technical means of the other Party” and “not to use deliberate concealment measures.”

Article XIII and XIV create a mechanism for ongoing review and amendment of the Treaty. Article XIII provides for the establishment [Page 259] of an SCC which serves as a forum for representatives of the Parties to meet regularly and consider matters of compliance, interpretation, exchange of information, amendment, as well as “possible changes in the strategic situation which have a bearing on the provisions of this Treaty.”

Article XIV states that “Each Party may propose amendments to this Treaty” and further provides that “the Parties shall together conduct a review of this Treaty” at five-year intervals for as long as the Treaty remains in force. Thus, the ABM Treaty is expressly made an adaptive instrument. The Parties are not locked into a regime which proves to be destabilizing or obsolete.

— Finally, the Treaty contains a safeguard against non-compliance or a shift in the strategic balance which threatens the vital security interests of either Party. Article XV provides that:

Each Party shall, in exercising its national sovereignty, have the right to withdraw from this Treaty if it decides that extraordinary events related to the subject matter of this Treaty have jeopardized its supreme interests.

— In this quick overview of the Treaty provisions I have tried to deal with the plain meaning of the Articles. The plain meaning certainly represents—at a minimum—the agreement which was reached by the U.S. and Soviet Governments—uncluttered by unilateral interpretations, individual expectations or just plain wishful thinking.

— I mentioned wishful thinking because in my own mind, this is unique to the U.S. ratification process. It is entirely conceivable that in the interest of “bringing home the bacon” some of our negotiators read well beyond the printed Treaty text in an effort to try to convince the Congress—and themselves that they had achieved mutual agreement.

THE NEW TECHNOLOGIES ISSUE

— Permit me now to present the case for the plain meaning of what limitations are to be applied to systems based on “other physical principles”; technologies which were not current at the time that the treaty was signed in 1972.

— The ABM Treaty provisions dealing with “current” and future technology can be most clearly understood by considering the two broad categories of ABM systems contemplated by the Treaty.

— “Current” systems. These are systems and components that comprised the “current” systems at the time the Treaty was negotiated. Article II defines such components as ABM interceptor missiles, ABM launchers and ABM radars. The deployment of such components is limited to locations and numbers specified in Article III and [Page 260] such components may be tested in conformity with Article IV and these components cannot be made mobile—sea, land or air based (Article V).

— In the category of future technology, ABM systems based on “other physical principles” are only addressed in Agreed Statement D. These are ABM systems with components based upon physical principles other than those used in ABM systems “current” at the time the Treaty was negotiated. These would be devices capable of substituting in the future for ABM interceptor missiles, ABM launchers or ABM radars.

— Agreed Statement D seems to imply that future systems based on other physical principles may be “created” and therefore may be developed and tested. However, in order to insure the fulfillment of the obligation not to deploy ABM systems and their components except as provided in Article III, the Agreed Statement imposes a duty on the Parties to confer and agree to “specific limitations” on these future systems before they are deployed.

— The use of the phrase “currently consisting of” in Article II could be read to mean that all future variants of existing ABM systems and components are covered by the Treaty. In that case, Article V would prohibit testing, development, and deployment of all mobile systems using new technologies.

— On the other hand, if Articles II and V had this effect, there would not be a need for the undertaking in Agreed Statement D to discuss “specific limitations” on future ABM systems “based on other physical principles.” The fact that “specific limitations” on future systems remain “subject to discussion” indicates that the Treaty by itself does not limit these systems.

— The negotiating history on this issue may be illustrative of what I referred to earlier as wishful thinking. The U.S. had long sought a ban on deployment of future systems, but did not seek to preclude development and testing. The Soviets resisted any restrictions on future systems. After months of negotiations they finally agreed to proscribe deployment of future systems in Agreed Statement D since, without it the Treaty would not operate to ban deployments of future systems.

— The negotiating record has no significant support for the proposition that Agreed Statement D limits the development or testing of future systems. On the contrary, since it begins with the prospect of their creation, these steps in bringing a system into existence appear to be sanctioned.

— What is far from clear is the public record prior to ratification and since. It is for this latter reason that we need to focus on the Treaty text and the negotiating record to find the mutually agreed interpretation.

[Page 261]

DISCUSSION

— In my estimation, we have a strong legal case and should not hesitate to take it to the Congress and our Allies—on its own merits.

— At this point I would like to ask each of you in turn to focus on the interpretation I have just given, and provide your views on how we should transition to this operative interpretation as it applies to our own SDI program.

George, would you care to lead?

— Cap, I believe you have some views on this.

— Paul, you have been most intimately involved with the ABM Treaty from the beginning. What do you think?

— Ken, your views?

— Bill (Crowe), it seems to me that you have studied a little law; do the Chiefs have anything to add?

[After the discussion we would recommend that you summarize before proceeding]

[If consensus is reached, as it may well be, recommending the simple assertion of a broader interpretation use the following remarks to permit the President to acknowledge this consensus and announce his decision modifying the consensus along the lines of the draft NSDD if he agrees]

— Mr. President, it appears that we have consensus that we have a strong case to announce the broader interpretation. Do you agree with a decision to do so now?

[If no consensus is reached, turn to the President for his views]

— Mr. President, we don’t have consensus here, do you need additional time to consider this or do you have a decision?

IMPLEMENTING THE DECISION

— As we all are keenly aware, execution is 95 percent of the solution. In this instance delay can only hurt our case, because we will be viewed as being unsure of ourselves.

— I think that we need to inform Congress, our allies and the press about this on our own terms; they must be informed of our deliberations on this matter and the decision that the President has made.

— With respect to the press, what do you all think about an on the record briefing by perhaps the State Department Legal Adviser, Judge Abe Sofaer, on Tuesday? Perhaps Paul, you could consider capturing the decision in your talk next week in San Francisco?

[Page 262]

— With the Press briefing, next week the real interest will be on the Hill. We will need a good plan to manage that activity. George, would you be willing to put some of your best people on this, and get, working with Defense and others, a plan for handling this in Congress over for the President to review Monday so that we can implement Tuesday?

— We will also need to inform our allies. I think this should be done via message on Monday. Views?

— Between now and Tuesday though we will have to move out in two very important directions. Before getting to the details of the Congressional and Allied gameplans though let me spend a few minutes on the real necessity of maintaining internal control and Administration cohesion on this issue.

— This has been a very contentious issue. Any time that you call into question something that has stood unchallenged for 13 years, you are going to have to overcome a certain amount of bureaucratic momentum to continue to view things the same way. In this instance I hope that we can capture the high ground and actually improve the prospects for the program on the Hill.

— For this reason it is very important that those of us in this room get quickly to our staffs and lay out the arguments and announce the decision. This is not the time to debate the points over again; it is time to march off smartly together.

CLOSING REMARKS

— Mr. President do you have anything further to add? Fine, thank you all for coming, an NSDD recording the decision will be issued shortly.

Talking Points Prepared in the National Security Council7

PROPOSED PRESIDENTAL TALKING POINTS

— The fundamental purpose of the SDI program is to determine whether and, if so, how advanced defensive technologies could contribute to the realization of this vision.

[Page 263]

— It is an objective worthy of our nation and a goal that I intend this nation pursue with all deliberate speed.

— At the same time, when we embarked on our SDI research, I directed that this research be conducted in full compliance with the ABM Treaty as we then understood it.

— What this discussion has led me to believe is that the assertions we have made for some time about what the ABM Treaty restricts with regard to advanced defensive technologies are not clearly demonstrable in the terms of the treaty as written, nor in the associated negotiating record.

— These assertions are a legacy which reflects more our hopes for the Treaty, made in the context of our assumptions about the future at the time the Treaty was negotiated and ratified.

— They do not appear to be an objective assessment of what was achieved and mutually agreed by the signed Treaty document.

— All this being said, over the last two years, and working under the constraints as we interpreted them at the inception of the program, our technical community designed our SDI research program to conform to a more restrictive view of our ABM Treaty obligations.

— This has entailed some price with respect to the speed of our progress, the overall cost of the program, and the level of technical uncertainty we face at each step in our research.

— But, nonetheless, they have crafted a program which, if consistently supported with the appropriate funding as requested, will permit us to achieve the goals set for it.

— Therefore, as long as the program receives the support needed to implement its carefully crafted plan, I don’t see the need to authorize the restructuring of the U.S. SDI program further towards the boundaries of Treaty interpretation which we could legitimately observe.

— This being the case, the issue of where exactly these boundaries lie is moot.
