STAR wars could be the greatest impetus
to arms control in a dozen years.
Or it could be the greatest barrier.
It all depends on what happens next.
So far, President Reagan's Strategic Defense
Initiative (SDI, or "star wars") has been a con-
spicuous incentive to arms control. Judging
from the vehemence of Soviet attacks on it, it
seems to be the major prod that got the Soviets
back to the negotiating table after they stalked
out in 1983.
At the same time, though, the Soviets are in-
sisting that no agreement on deep cuts in nu-
clear offensive weapons is possible unless the
United States gives up any notion of a space-
and land-based defense against Soviet intercon-
tinental missiles.
And what is the lesson of this?
To hard-liners in the Reagan administration
- primarily Pentagon civilians and Air Force
officers directing the SDI program - the Soviet
opposition proves that SDI is a good thing and
should at all costs be preserved intact. To
moderates in the administration, it shows that
SDI could be a valuable lever to extract - for
the first time in the nuclear age - major reduc-
tions in nuclear weapons rather than just ceil-
ings on huge existing arsenals.
To sort out the conflicting points of view, sev-
eral issues must be addressed:
? What SDI options are technically feasible?
? What would be the effect of each of these
on nuclear stockpiles and the threat of nuclear
holocaust?
? What policy alternatives - or what com-
binations of SDI and arms control - are there?
FeasMty
In the four decades of the nuclear era, no
physical "defense" against an enemy's attack
has thus far been possible, simply because of
the scale of nuclear blast. The 10 or 30 or even
50 percent attrition of enemy planes that was ef-
fective in halting air raids in World War II has
no meaning, when a leakage of even 1 percent of
10,000 strategic, nuclear warheads through to-
day's defense lines would bring the devastation
of 1, 000 Hiroshimas.
Thus, in the past four decades, prevention of
nuclear war - "deterrence" - has replaced
physical "defense" as the central military mis-
sion. And both sides' inhibitions against attack-
ing the enemy have rested precisely on the
knowledge that, since no defense is possible,
any attack. would call forth an intolerable
reprisal.
Will technological advances change this and
once again make physical defense conceivable?
Last fall's report on "Ballistic Missile De-
fense Technologies" by the Congressional Of-
fice of Technology Assessment (available for
$12 from the Superintendent of Documents, US
Government Printing Office, Washington, D.C.
20402) tries to answer this question by assess-
ing four potential SDI programs. These range
from a modest protection of some land-based
intercontinental ballistic missiles to a very am-
bitious defense of civilians in cities.
The last goal was what Mr. Reagan originally
envisioned in his speech launching SDI in
March 1983.
Administration spokesmen have since low-
ered their sights, however, and are now aiming
for a system that would be only partially effec-
tive: strategic defense combined with targeted
cuts of 50 percent in the superpowers' offensive
weapons. Such a combination could increase
Soviet uncertainty; it would not actually re-
pulse an.attack.

Thus, as the OTA study put it, "The motive
for a Soviet decision to escalate a crisis to a cen-
tral nuclear war might not be to gain a clear po-
litical or military objective: Instead, it may be
to reduce what they fear could be a severe loss.
In_ time of crisis we would not want the Soviet
leadership to calculate that its least bad option
was to start a nuclear war."

The arms control options
The spectrum of SDI and arms control
choices that now face the superpowers ranges
from unhindered strategic defense and no arms
control, a course American hard-liners could
support, to offensive arms limits but no strate-
gic defense whatever, the course Moscow cur-
rently espouses. In between are various poten-
tial trade-offs of mutual cuts in offensive
weapons against mutual restraints on strategic
defense.
? The first extreme - all SDI and no arms
control - is the probable result if the US con-
tinues to insist that SDI is non-negotiable. In
the most comprehensive unclassified study of
Soviet reactions to date (an Adelphi Paper of
the International Institute for Strategic Stud-
ies), Stephen Meyer of the Massachusetts Insti-
tute of Technology argues that the Soviets will
never agree to deep offensive cuts unless SDI is
curtailed. This impasse would lead to open-
ended proliferation of offensive systems by
both sides as the cheapest and quickest foil to
the adversary's developing strategic defense.
Hard-liners would view such an outcome
with equanimity. They argue that the US would
win this race, since the US is almost twice as
rich and leads the Soviet Union in almost all
categories of technology important for nuclear
weapons and defense (according to Pentaton
listings).
The moderates in Washington - primarily
some activist ex-officials, the State Depart-
ment, and, on occasion, members of the Joint
Chiefs of Staff - are far less convinced of this
scenario. They point to a Central Intelligence
Agency study indicating that the Soviet Union
would quickly outpace the US in unrestrained
production of missiles because of ready Soviet
assembly lines and the traditional Russian fe-
tish of quantity over a itv Political c ture,
too, would work against the US in an
unconstrained arms race, given Americans'

sought by the Reagan administration for pre- .
liminary research during the first six years of
SDI. The total price tag for a deployed system
is hard to tally, but some estimates run as high
as $1 trillion.
? The other. extreme - all arms control and
no strategic defense - is only a hypothetical al-
ternative. No one is advocating this within the
Reagan administration, not even moderates,
and no Western Kremlinologist believes this re-
presents anything other than a negotiating ploy
by Moscow, given the Soviets' own vigorous re-
search in strategic defense.
What some moderates in Washington do ad-
vocate, however - and what Soviet leaders
keep hinting at in public (though never in offi-
cial negotiations) is some trade-off of mutual
restraints on SDI for mutual deep cuts in offen-
sive nuclear weapons.
Moderates say this would make sense both
for arms control and for strategic defense -
since indications are that strategic defense
would prove effective only against a limited and
predictable number of warheads. As the OTA
study put it (citing Reagan administration con-
currence), "an all-out attack can be overcome
only if the attack is limited by restraints on the
quantity and quality of the attacking forces."
Washington is in fact proposing to Moscow
at this point that the two superpowers agree on
a mix of strategic defense and deep cuts (though
just how negotiable SDI might eventually be-
come is not yet clear). Various moderates argue
that a mix of warhead restraints and limited
SDI - probably confined to ICBM defense to
strengthen rather than undermine deterrence -
would be far more effective and cheaper in sta-
bilizing relations and preventing nuclear war
than an all-out race. They also contend that ver-
ification of arms control compliance could be
made reliable enough so that anything beyond
marginal cheating would be detected.
Hard-liners, by contrast, fear that any equal
limits on both the superpower arsenals would,
in practice, hobble Washington much more than
Moscow, since the closed Soviet society can
more easily cheat than can the US. If the cost of
agreed offensive cuts is mutual restraint on
SDI, then that cost is too high, they say.
As the OTA study concluded, the choices in
SDI and arms control require "a balance of op-
portunities against risks. The SDI offers an op-
portunity to substantially increase our nation's
safety if we obtain great technological success
and a substantial degree of Soviet coopera-
tion.... The SDI carries a risk [that it] could
bring on an offensive and defensive arms race
[and that] deployment, if it took place without
Soviet cooperation, could create severe
instabilities."
