The Anti-Ballistic Missile Treaty (ABM Treaty or ABMT) was a treaty between the United States of America and the Union of Soviet Socialist Republics
on the limitation of the anti-ballistic missile (ABM) systems used in defending
areas against missile-delivered nuclear weapons. On May
26 1972, the President of the United
States, Richard Nixon and the General Secretary of the Communist Party of the Soviet
Union, Leonid Brezhnev signed the Anti-Ballistic Missile Treaty. The treaty was
in force for thirty years, from 1972 until 2002. On June 13 2002,
six months after giving the required notice of intent, the US withdrew from the treaty.
Early history
Throughout the late 1950s and into the 1960s, the United States had been developing a series of missile systems with the
ability to shoot down incoming ICBM warheads. During this period the
US maintained a lead in the number and sophistication of their delivery systems, and considered the defense of the US as a part
of reducing the overall damage inflicted in a full nuclear exchange. As part of this defence, Canada and the US established the North American Air Defense Command (now called North American Aerospace Defense
Command NORAD).
By the early 1960s, US research on the Nike Zeus missile system (see Project Nike) had developed to the point where small improvements would allow it to be used as the basis of
a "real" ABM system. Work started on a short-range, high-speed counterpart known as the Sprint to provide defense for the ABM sites themselves. By the mid-1960s, both systems showed enough
promise to start development of base selection for a limited ABM system dubbed Sentinel. However, due to political debate,
Sentinel never expanded beyond defense of missile-bases.
An intense debate broke out in public over the merits of such a system. A number of serious concerns about the technical
abilities of the system came to light, many of which reached popular magazines such as Scientific American. This was based on lack of intelligence information and reflected the American
nuclear warfare theory and military doctrines. The Soviet doctrine called for development of their own ABM system and return to
strategic parity with the US. This was achieved with the operational deployment of the A-35 ABM system, which still remain the only operational ABM system to this day.
As this debate continued, a new development in ICBM technology essentially rendered the points moot. This was the deployment
of the Multiple Independently targetable Reentry Vehicle (MIRV) system, allowing a single ICBM missile to deliver several
warheads at a time. With this system the USSR could simply overwhelm the ABM defense system with numbers, as the same number of
missiles could carry ten times more warheads. Upgrading it to counter the additional warheads would cost more than the handful of
missiles needed to overwhelm the new system, as the defenders required one rocket per warhead, whereas the attackers could place
10 warheads on a missile with more affordable cost than development of ABM. To further protect against ABM systems, the Soviet
MIRV missiles were equipped with electronic countermeasures and heavy decoys, with heavy missiles like R-36 carrying as many as
40 of them.[1] These decoys would appear as
warheads to ABM, effectively requiring engagement of 50 times more targets than before and rendering defense ineffective.
At about the same time, the USSR reached strategic parity with the US in terms of ICBM forces. A nuclear war would no longer
be a favorable exchange for US, but both countries would be devastated. This led in the West to the concept of mutually assured destruction, MAD, in which any changes to the strategic balance had
to be carefully weighed. ABMs, now ready for use after over a decade of development, seemed to be far too risky – it was better
to have no defense than one that might trigger a war.
In the East however, the concept of MAD was almost entirely unknown to the public, studied only by those in the Soviet
military and Government who analysed Western military behaviour. Soviet military theory fully involved the mass use of nuclear
devices, in combination with massive conventional forces.[2]
As relations between the US and USSR warmed in the later years of the 1960s, the US first proposed an ABM treaty in 1967. This
proposal was rejected. Following the proposal of the Sentinel and Safeguard decisions on American ABM systems, the Strategic Arms
Limitation Talks (SALT I talks) began in November 1969. By 1972
agreement had been reached to limiting strategic offensive weapons and strategic defensive systems. Each country was allowed two
sites at which it could base a defensive system, one for the capital and one for ICBM silos (Art. III). The treaty was signed in
Moscow on May 26, 1972 and ratified by the US Senate on
August 3, 1972.
The 1974 Protocol reduced the number of sites to one per party, largely because neither country had developed a second site.
The sites were Moscow for the USSR and Grand Forks
Air Force Base, North Dakota, since its Safeguard facility was already under construction, for the US.
It was seen by many in the West as a key piece in nuclear arms control, being an implicit recognition of the need to
protect the nuclear balance by ensuring neither side could hope to reduce the effects of retaliation to acceptable
levels.
In the East, however, it was seen as a way to avoid having to maintain an anti-missile technology race at the same time as
maintaining a missile race. The US at this time was allocating about 5% of their GDP on military spending. The USSR was
allocating about 40% of their GDP, due to smaller overall economic base.[3]
For many years the ABM Treaty was, in the West, considered one of the landmarks in arms limitations. It was perceived as
requiring two enemies to agree not to deploy a potentially useful weapon, deliberately to maintain the balance of power and as such, was also taken as confirmation of the Soviet
adherence to the MAD doctrine.
After the SDI announcement
The treaty was undisturbed until Ronald Reagan announced his Strategic Defense Initiative (SDI) on March 23
1983. Reagan stated that SDI was "consistent with... the ABM Treaty" and he viewed it as a
defensive system that would help reduce the possibility of mutual assured
destruction (MAD) becoming reality; he even suggested that the Soviets would be given access to the SDI technology.
The project was a blow to Yuri Andropov's so-called "peace offensive". Andropov said
that "It is time they [Washington] stopped... search[ing] for the best ways of unleashing nuclear war... Engaging in this is not
just irresponsible. It is insane".[4]
SDI research went ahead, although it did not achieve the hoped result. SDI research was cut back following the end of Reagan's
presidency, and in 1995 it was reiterated in a presidential joint statement that "missile defense systems may be deployed...
[that] will not pose a realistic threat to the strategic nuclear force of the other side and will not be tested to... [create]
that capability." This was reaffirmed in 1997.
However, as is often the case, the unintended effects of a policy proved to be far more profound than the intended
effects.
The competitive pressure of SDI added considerable additional strains to the Soviet economy. The Soviet economy was
essentially still a war economy after World War II, with increase of civilian production disproportionally small compared to
growth of defense industry. It was already slowly becoming clear that the Soviet economy could not continue as it was, with
military spending absorbing 40% of GDP; the additional demands from the military-industrial complex to compete with SDI
exacerbated this problem and was part of the longer term situation which led to Gorbachev's efforts at economic reform (which
failed, due to the need for initial political reform, which in turn led to his efforts to achieve political reform, which led to
the fairly accidental collapse of the Party).
After the dissolution of the Soviet Union in December 1991 the status of the treaty became unclear, debated by members of
Congress and professors of law, Succession of the ABM Treaty,State Succession and the Legal Status
of the ABM Treaty, and Miron-Feith Memorandum. In 1997, a memorandum of
understanding[5] between the US and four of the
former USSR states was signed and subject to ratification by each signatory, however it was not presented to the US Senate for
advice and consent by Bill Clinton.
On December 13, 2001, George W. Bush gave Russia notice of the United States' withdrawal from
the treaty, in accordance with the clause that requires six months notice before terminating the pact. This was the first time in
recent history the United States has withdrawn from a major international arms treaty. This led to the eventual creation of the
Missile Defense Agency.[1]
Supporters of the withdrawal argued that it was a necessity in order to test and build a limited National Missile Defense to protect the United States from nuclear blackmail by a rogue state. The withdrawal had many
critics as well as supporters. John Rhinelander, a negotiator of the ABM treaty, predicted that the withdrawal would be a "fatal
blow" to the Nuclear Non-Proliferation Treaty and would lead to a
"world without effective legal constraints on nuclear proliferation."
Reaction to the withdrawal by both the Russian Federation and the People's Republic of China was much milder than many had predicted, following months of
discussion with both Russia and China aimed at convincing both that development of a National Missile Defense was not directed at them. In the case of Russia, the United States
stated that it intended to discuss a bilateral reduction in the numbers of nuclear warheads, which would allow Russia to reduce
its spending on missiles without decrease of comparative strength. Discussions led to the signing of the Strategic Offensive Reductions Treaty in Moscow on 24 May 2002. This treaty mandated the deepest ever cuts in deployed strategic nuclear warheads, without actually mandating
cuts to total stockpiled warheads.
