MISSILE DEFENCES
A shield in space
America wants to build a new system of missile defences. This is not popular
with others, whether allies or potential foes
"LATE next spring, when the ice melts and L the wind subsides to a moderate
gale, barges based in Seattle may well be making the 3,000-mile voyage to
deliver building materials to an Alaskan island called Shemya. The erection
of an ultra-sensitive radar installation on this unforgiving terrain, where
building is possible only for a few weeks every summer, would mark the first
step in a crash programme to provide the United States with a shield against
certain limited types of rocket attack.
Although the Pentagon has already embarked on half-a-dozen other programmes
designed to stop missiles in mid-flight, this
will be the first time a nuclear power has openly set out to defend its
entire territory from such attacks. But before the barges can start plying
the north Pacific, a big change will have occurred, for better or worse, in
international diplomacy. From the moment the first concrete is poured into
Shemya's soil, the United States will be in breach of the current terms of
the 1972 Anti-Ballistic Missile (ABM) treaty, under which America and the
Soviet Union agreed that neither would build a comprehensive defence against
the other's long-range nuclear arsenal.
That accord, designed as a guarantee against a "first strike" by either
side, has been widely criticised, especially on America's political right,
as a hangover from the cold war that is no longer useful in a world where
any rogue state can acquire deadly missiles. Russia and China, on the other
hand, have expressed horror at the idea of abrogating the treaty. They fear
(plausibly in China's case, less so in Russia's) that their own nuclear
arsenals could be rendered useless by an American shield-while America could
still use its rockets with impunity.
Among the main provisions of the treaty are strict curbs on the construction
of radars powerful enough to track incoming missiles in space. So, before
starting to build the $5oom radar in Alaska, the American government must do
one of two things. It could exercise its option to withdraw from the ABM
treaty on six months' notice-which would delight Republicans in Congress,
but could plunge relations with Russia and China into crisis and strain the
Atlantic alliance.
The alternative course, which President Bill Clinton hopes to follow during
his final months in office, is to negotiate with Russia the changes to the
treaty that would be needed to make a limited national missile defence (NMD)
system possible. In order to do this, America must convince Russia that its
proposed anti-missile shield is designed to ward off a handful of rockets
from a North Korea or an Iran-not a massed attack from the still-formidable
Russian arsenal.
The treaty changes America is now proposing are only the bare minimum
required to allow work in Alaska to begin. Broader changes would be needed
before implementing in full the Pentagon's current plan for an anti-missile
system with a second interceptor site, in North Dakota, and
superhigh-frequency radar stations in Greenland, Britain and possibly South
Korea as well as other parts of the United States. The immediate plan is to
deploy 20 interceptors, able to stop a few crude missiles, in Alaska by
2005; but by the end of the decade there could be as many as 250
interceptors, capable of knocking out a "few dozen" missiles.
Reassuring Russia
American diplomats are working hard to convince the Russians that, even at
its maximum stretch, such a shield would not render Russia's nuclear
deterrent ineffective. This would still be true, they say, even if, as
Russia has proposed, a new agreement were to cut the number of warheads
deployed by America and Russia to 1,500 each. Under the Start-2 accord, each
side's total will come down to 3,500 by 2007. Follow-on Start-3 talks aim to
Cut to 2,000-2,500 warheads. The Pentagon said last week it would be
"uncomfortable" about going lower than that.
Even if it successfully deploys a limited shield, and both sides' arsenals
are slashed, the United States would still not be able to strike Russia with
impunity, American officials have assured their Russian counterparts. The
Pentagon would have to assume that Russia still had a huge number of
warheads, based on land and sea, primed for "launch on warning" of an
American attack. By sending this message of reassurance, the Clinton
administration has exposed itself to the charge that it is positively
encouraging its cold-war foe to maintain a large, sophisticated arsenal on
hair-trigger alert.
In any case, Russia's new president, Vladimir Putin, whom Mr Clinton will be
meeting on June 4th, seems so far to be unimpressed. Senior American
officials admit that Russia is not yet convinced of the need to amend the
ABM treaty, so the presidents will also focus on other arms-control
measures, such as a deal to destroy large amounts of plutonium.
If the two presidents find they disagree sharply over ABM issues, the stage
could be set for a hot diplomatic summer. America's European allies have
concerns of their own about the proposed missile shield. Their biggest worry
is that the ABM issue will cause a general downturn in relations with Russia
and China, whose consequences would be felt in Europe. "Quitting the ABM
treaty would send an unfortunate signal about America's readiness to play by
agreed rules rather than unilaterally," says Francois Heisbourg, a French
security analyst.
Mr Clinton's room for manoeuvre in this political and diplomatic game is
small. The Pentagon says a decision to start the NMD programme must be made
by this autumn; otherwise it will be impossible to start work in Alaska next
year, and there will be no hope of meeting the goal of erecting a modest
anti-missile shield by 2005.
According to the white House, the timetable is based on estimates that North
Korea could have developed a missile capable of hitting the United States in
five years time, if not sooner. But Zbigniew Brzezinski, a former national s
ecurity adviser, believes one aim of the timetable is to shield
Vice-President AI Gore from charges that he would be less keen on "defending
American families" than his Republican rival, George W. Bush. Mr Bush said
last week that, as president, he would deploy anti-missile defences as soon
as possible. But he questioned the need for an immediate decision.
In political terms, the anti-missile network proposed by Mr Clinton, calling
for the eventual deployment Of 250 interceptors, is nowhere near robust
enough to satisfy the keenest supporters of anti-missile defence on the
Republican side. They want to withdraw from the ABM treaty immediately and
start constructing a multi-layered system of interceptors, based at sea and
in space as well as on land.
Meanwhile, American citizens-and the rest of the world-are left wondering
whether they will be safer or in greater danger if work starts on
anti-missile defences. They want to know whether the perceived threat from
rogue missiles is real, whether the proposed shield would work and what the
economic and diplomatic costs will be.
The real threat
The strongest arguments in favour of developing anti-missile defences have
to do with the proliferation of ballistic missiles and of the know-how
needed to tip them with nuclear, chemical or biological warheads, which are
lumped together under the catch-all term of -weapons of mass destruction"
(WMD). General Ronald Kadish, the head of the Pentagon's
ballistic-missile-defence programme, has said that at least 20 countries
possess either short- or medium range ballistic missiles, while "two dozen"
either have developed or can develop a WMD capacity. Because countries like
North Korea will sell rocket technology to anybody who has the money, the
pace of proliferation has been accelerating. "Co-operation between rogues is
getting deeper and wider all the time," according to Ranger Associates, a
Washington missile consultancy.
But how many of these regional pariahs could develop missiles of long enough
range to threaten the United States with non-conventional weapons? Only a
handful. The Central Intelligence Agency has projected that over the next 15
years, in addition to the existing arsenals of Russia and China, America is
"likely" to face a missile threat from North Korea. Such a threat is
"probable" from Iran and "possible" from Iraq.
Regimes may change for the better, of course. Still, the pace at which
anti-American regimes can develop ballistic-missile technology has often
been underestimated by western experts. North Korea's launch in August 1998
of a three-stage rocket shocked the world; since last autumn it has been
observing a freeze on new flight tests, although it is believed to be
pursuing other research.
But would such rockets ever be fired against the United States? it would
seem suicidal. it is possible, nonetheless, to imagine a regional crisis in
which America's freedom to support local allies would be hampered by the
knowledge that its territory could, however hypothetically, be attacked with
missiles. Yet for the Pentagon to feel that the homeland was immune, it
would need to be sure that its shield would be able to stop allcorners; and
that degree of certainty has still not been reached.
There are also more immediate dangers: the use of crude short-range missiles
in regional conflicts, against American bases or American allies; or a
non-conventional attack on the United States by some means other than
long-range ballistic missiles, such as truck bombs or even sea-launched
rockets. This has prompted some defence specialists, not all of them doves,
to suggest that the NMD programme involves spending far too much money, and
incurring huge diplomatic costs, for a threat which is by no means the most
acute.
How it would work
The cost of Mr Clinton's proposed system - estimated by the Pentagon at 27
billion US dollars over 20 years for a single interceptor site, plus
radars - looks small compared with some other defence programmes. The
Congressional Budget Office reckons the full system, without extra
satellites, could cost 50 billion US dollars. Obviously the more complex the
defences attempted, the higher the price tag.
How would Mr Clinton's proposed NMD system deal with a rocket attack? The
idea is that far above the atmosphere, near the top of its flight path, the
rogue rocket would be stopped in its tracks. An American missile, guided by
one of the most powerful radar systems ever built, and equipped with
detectors of its own, would home in on the intruder-by this stage a
cone-shaped object, five feet long-and smash it to pieces.
The hostile launch would first have been detected by space-based sensors.
Then a network of ground-based radars would erect "search fences- to detect
the intruder and consider how to stop it. The powerful x-band radar, based
initially at Shemya, would follow the attacker as it soared above the
atmosphere, while a command centre deep in Colorado's Cheyenne mountains
directed the launch of an interceptor. once the interceptor or "kill
vehicle" got close enough to the target, it would start using its own
sensors to tell the real rocket from any decoys.
So far, the Pentagon has tried out the concept with two attempted
intercepts, each costing about $loom. One, last October, was a success
(although its terms of reference were restricted), while the second, in
January, narrowly failed. As a result of this failure, a third test (of a
total of 19) has been postponed from April to July. The Pentagon is then due
to give the president an estimate of whether the system can be deployed in
five years' time. General Kadish describes the 2005 timetable as "high
risk", because five very sophisticated components have to be developed
concurrently and then tied together, much faster than military planners
would like.
Decoys and alternatives
One of the strongest arguments put forward by the sceptics (on both right
and left) is that the system currently proposed would be too vulnerable to
counter-measures. A report issued in April by the Union of Concerned
Scientists argued that any country clever enough to design ballistic
missiles would also be able to make decoys of sufficient sophistication to
fool the interceptors. According to the ucs, decoys can be particularly
effective outside the atmosphere, where there is no resistance from the air,
and where objects of different weights and shapes behave in the same way.
One technique would be to wrap the warhead in a material called aluminised
mylar and simultaneously to release balloons coated with the same substance;
another would be to cool the warhead with a shroud of liquid nitrogen,
making it harder for the interceptor to home in. If a rogue wanted to tip
his rockets with chemical or biological warheads, they would almost
certainly be split up into "bomblets" or submunitions which, the ucs
believes, would be too numerous for interceptors to stop.
In short, it would be hard to stop missiles in space with land-based
interceptors. So why not stop them earlier in their flight, from the sea?
The main argument against sea-based defences is that these would require a
much more radical rewriting of the ABM treaty. In other words, they would be
harder to sell to the Russians. Already the Pentagon's effort to develop a
sea-based shield against medium range missiles, known as Navy Theatre Wide,
has been limited in scope-or as critics would say, "dumbed down" - in order
to reassure Russia that it will not be used as a proxy for a system to
defend America.
The advantage of a system like Navy Theatre Wide, which should be
operational by 2007, is that it aims, ideally, to stop missiles in their
ascent phase-in other words, before they reach their highest point. This
makes it harder for the enemy to use counter-measures, although the ships
themselves would be vulnerable to attack.
Better still, in theory, would be a system that knocked out enemy missiles
in their boost phase, a few minutes after being launched. The only Pentagon
effort that is explicitly designed to achieve that purpose is the air
force's Airborne Laser programme, which is probably a decade away from
deployment. Tantalising as it sounds, the success of this effort is far from
assured-and it would be anathema to the Russians.
The diplomatic costs
The diplomatic, economic and military consequences of the American decision
are already being felt in many different parts of the world. In Greenland,
local politicians are worried that the upgrading of an American radar
station, as part of the NMD network, will make the vast, icy landmass a
target for enemy attack. In Canada, which might well
have a role to play in tracking incoming missiles, officials are furious
about a remark, by an American admiral, that a missile heading towards
Ottawa might not be stopped unless Canada joins the shield. In NATO
capitals, diplomats are fretting over the "decoupling- of the United States,
protected by an anti-missile shield, from its European allies.
in China, which has threatened to accelerate its own strategic arms build-up
in response to the American shield, officials are convinced that the shield
is directed against them; they speak ominously about a new cold war.
Although the Chinese are not party to the ABM treaty, they are-like the
other minor nuclear powers-a beneficiary of its curbs on anti-missile
defences. They have suggested that playing about with the treaty could wreck
the fabric of arms control. Such talk is a veiled threat that China would
not only boost its own arsenal but withdraw promises to stop exporting
dangerous defence technology.
On Capitol Hill, meanwhile, Republican hawks such as Senator Jesse Helms
have given warning that any deal with Russia to keep the ABM treaty, and
prevent America building a more ambitious anti-missile shield, will be "dead
on arrival" in Congress.
All this has prompted supporters of missile defences to suggest that more
imaginative ways ought to be found of maintaining Russian confidence, while
giving America a free hand to defend itself, Russia itself has put forward
proposals for countering the threat of rogue missiles, and for reducing the
risk of an accidental nuclear exchange.
The Russian proposals include "broad international participation" in an
arrangement to swap information about missile launches; and a set of
incentives designed to encourage rogue missile-makers to abandon their
efforts by offering them commercial space technology, and security
guarantees.
America rejects the idea of security guarantees and is wary of any formal
system of incentives, available to any country that starts making rockets
and then stops. Moreover, help for space programmes could be misused to
develop longer-range missiles. But the Americans have not ruled out
extending an information-sharing regime beyond Washington and Moscow.
What about bolder initiatives from the American side, designed to reassure
Russia while ensuring greater freedom of action for the Pentagon? Ever since
the "star wars" programme of the Autos, advocates of anti-missile defence
have insisted that it should be possible to break the -balance of terror-
logic without alienating Russia. In practice, it is hard to think how this
might safely be done. But unless it can, America could find itself in the
worst of all worlds: incurring the huge diplomatic cost of withdrawal from
the ABM treaty, without any real guarantee that rogue missiles could be
stopped.
