Anti-Ballistic Missile Treaty at Wikisource |
The Anti-Ballistic Missile Treaty, also known as the ABM Treaty or ABMT, was an arms control treaty between the United States and the Soviet Union on the limitation of the anti-ballistic missile (ABM) systems used in defending areas against ballistic missile-delivered nuclear weapons. It was intended to reduce pressures to build more nuclear weapons to maintain deterrence. [1] Under the terms of the treaty, each party was limited to two ABM complexes, each of which was to be limited to 100 anti-ballistic missiles. [2] : 115
Signed in 1972, it was in force for the next 30 years. [3] In 1997, five years after the dissolution of the Soviet Union, four former Soviet republics agreed with the United States to succeed the USSR's role in the treaty, with Russia assuming all rights and obligations as the successor state of the Soviet Union. Citing purported risks of nuclear blackmail, the United States unilaterally withdrew from the treaty in June 2002, leading to its termination.
Throughout the late 1950s and into the 1960s, the United States and the Soviet Union had been developing missile systems with the ability to shoot down incoming Intercontinental ballistic missile (ICBM) warheads. During this period, the US considered the defense of the US as part of reducing the overall damage inflicted in a full nuclear exchange. As part of this defense, Canada and the US established the North American Air Defense Command (now called North American Aerospace Defense Command).
By the early 1950s, US research on the Nike Zeus missile system had developed to the point where small improvements would allow it to be used as the basis of an operational ABM system. Work started on a short-range, high-speed counterpart known as 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. In 1967, the US announced that Sentinel itself would be scaled down to the smaller and less expensive Safeguard. Soviet doctrine called for development of its own ABM system and return to strategic parity with the US. This was achieved with the operational deployment of the A-35 ABM system and its successors, which remain operational to this day.
The development of multiple independently targetable reentry vehicle (MIRV) systems allowed a single ICBM to deliver as many as ten separate warheads at a time. An ABM defense system could be overwhelmed with the sheer number of warheads. [4] : 217 Upgrading it to counter the additional warheads would be economically unfeasible: The defenders required one rocket per incoming warhead, whereas the attackers could place 10 warheads on a single missile at a reasonable cost. To further protect against ABM systems, the Soviet MIRV missiles were equipped with decoys; R-36M heavy missiles carried as many as 40. [5] These decoys would appear as warheads to an ABM, effectively requiring engagement of five times as many targets and rendering defense even less effective.
The United States first proposed an anti-ballistic missile treaty at the 1967 Glassboro Summit Conference during discussions between U.S. Secretary of Defense Robert McNamara and Chairman of the Council of Ministers of the Soviet Union Alexei Kosygin. McNamara argued both that ballistic missile defense could provoke an arms race, and that it might provoke a first-strike against the nation fielding the defense. Kosygin rejected this reasoning. They were trying to minimize the number of nuclear missiles in the world. [6] : 4-5 Following the proposal of the Sentinel and Safeguard decisions on American ABM systems, the Strategic Arms Limitation Talks began in November 1969 (SALT I). By 1972 an agreement had been reached to limit 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.
The treaty was signed during the 1972 Moscow Summit on 26 May by the President of the United States, Richard Nixon and the General Secretary of the Communist Party of the Soviet Union, Leonid Brezhnev; and ratified by the U.S. Senate on 3 August 1972.
The 1974 Protocol reduced the number of sites to one per party, largely because neither country had developed a second site. [7] The sites were Moscow for the USSR and the North Dakota Safeguard Complex for the US, which was already under construction.
The Treaty limited only ABMs capable of defending against "strategic ballistic missiles", without attempting to define "strategic". It was understood that both ICBMs and SLBMs are obviously "strategic". [8] : 37 Neither country intended to stop the development of counter-tactical ABMs. The topic became disputable as soon as most potent counter-tactical ABMs started to be capable of shooting down SLBMs (SLBMs naturally tend to be much slower than ICBMs), nevertheless both sides continued counter-tactical ABM development. [8] : 37
On 23 March 1983, Ronald Reagan announced the Strategic Defense Initiative, a research program into ballistic missile defense which he claimed would be "consistent with our obligations under the ABM Treaty". Reagan was wary of mutual deterrence with what he referred to as the "Evil Empire", and wanted to escape the traditional confines of mutual assured destruction. [9] : 99 The project was a blow to Yuri Andropov's overtures for peace. Andropov said, "It is time Washington stopped thinking up one option after another in search of the best way of unleashing nuclear war in the hope of winning it. To do this is not just irresponsible. It is madness". [10] [11]
Regardless of the opposition, Reagan gave every indication that SDI would not be used as a bargaining chip and that the United States would do all in its power to build the system. The Soviets were alarmed because the Americans might have been able to make a nuclear first strike possible. In The Nuclear Predicament, Beckman claims that one of the central goals of Soviet diplomacy was to terminate SDI. He went on to state that a surprise attack from the Americans would destroy much of the Soviet ICBM fleet, allowing SDI to defeat a "ragged" Soviet retaliatory response. The Soviets could not afford to ignore Reagan's new endeavour; therefore, their policy at the time was to enter negotiations with the Americans. [12] [13] By 1987, however, the USSR withdrew its opposition, concluding the SDI posed no threat and scientifically "would never work". [14] [15]
SDI research went ahead, although it did not achieve the hoped-for 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.
The ABM Treaty prohibited "National Missile Defense" (NMD), but some interpreted it to allow more limited systems called "Theater Missile Defense" (TMD). [16] This is because Article II of the treaty defined "ABM Systems" as those that "counter strategic missiles", which are typically defined as those with "intercontinental capability". [16] Thus, TMD supporters argued, the treaty did not prohibit systems that defended against the countering of theatre ballistic missiles. The US had already developed and used such systems, including the Patriot Missile during the Gulf War. [16]
The problem arose as TMD systems could also potentially be capable of countering strategic ballistic missiles, not just theatre ballistic missiles. [16] The Clinton administration began negotiations with the Russian Government in 1993 to make amendments to the treaty. After much discussion, the American president, Bill Clinton, and his Russian counterpart, president Boris Yeltsin, signed an addendum to the treaty on September 9, 1997. According to these new agreements, the treaty permitted missile defense systems to have a velocity up to 5 km/s as long as it had not been tested against targets traveling faster than 5 km/s. [17]
The 1997 agreement were eventually ratified by the Russian parliament on May 4, 2000 (along with START II treaty). [17] However, it was opposed in the U.S. Senate by some Republican senators led by the hawkish anti-communist Jesse Helms. [17] As a result, Clinton never submitted the agreement to Congress, fearing that Helms would stall their ratification or defeat it outright. [17]
Although the Soviet Union ceased to exist in December 1991, in the view of the U.S. Department of State, the treaty continued in force. [18] Russia was confirmed as the USSR's successor state in January 1992. [19] Belarus and Ukraine were treated as successors at the ABM review conference in October 1993 and Kazakhstan was added as a successor shortly after. [19] Belarus, Ukraine and Kazakhstan became regular participants at ABM treaty meetings known as Standing Consultative Commissions. [19] An additional memorandum of understanding was prepared in 1997, establishing Belarus, Kazakhstan, the Russian Federation, and Ukraine as successor states to the Soviet Union, for the purposes of the treaty. The US considered only extending the obligations to these countries, and not all, as only these ones had significant ABM assets. [20] As the ABM treaty allowed for only a single ABM deployment, the State Department deemed that only a single ABM system would be collectively permitted among Russia, Ukraine, Kazakhstan and Belarus. [21]
In the United States, there was a debate on whether after the dissolution of the USSR, the ABM Treaty was still in effect. A month after the USSR's dissolution, President George H. W. Bush affirmed the ABM Treaty and regarded Russia as USSR's successor. [22] Russia also accepted the ABM Treaty. [22] Later on, President Clinton would affirm the validity of the treaty, as would President George W. Bush [20] (before he terminated it). However, some Americans (mostly conservative Republicans [20] ) argued that the treaty was not in effect because the USSR had no successor state. This was deemed inconsistent, as Russia did indeed inherit the USSR's obligations (including its UNSC seat, its debts, its agreements on nonproliferation etc.). [20] Former CIA director James Woolsey argued that in order for the treaty to remain in force, both the US and Russia had to accept it, and that President Clinton could not accept it without Congressional approval. [22] According to Michael J. Glennon, Congress acknowledged the treaty in 1996, when it passed a law restricting President Clinton's ability to modify the treaty. [22] [20]
On 13 December 2001, George W. Bush gave Russia notice of the United States' unilateral withdrawal from the treaty, in accordance with the clause that required six months' notice before terminating the pact—the first time in recent history that the United States has withdrawn from a major international arms treaty. [23] This led to the eventual creation of the American Missile Defense Agency. [24]
Supporters of the withdrawal claimed 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. However, the withdrawal had many foreign and domestic critics, who said the construction of a missile defense system would lead to fears of a U.S. nuclear first strike, as the missile defense could blunt the retaliatory strike that would otherwise deter such a preemptive attack. John Rhinelander, a negotiator of the ABM treaty, predicted that the withdrawal would be a "fatal blow" to the Non-Proliferation Treaty and would lead to a "world without effective legal constraints on nuclear proliferation". Former U.S. Secretary of Defense William Perry also criticized the U.S. withdrawal as a very bad decision. [25]
The then-newly elected Russian president, Vladimir Putin, responded to the withdrawal by ordering a build-up of Russia's nuclear capabilities, designed to counterbalance U.S. capabilities, although he noted there was no immediate danger stemming from the US withdrawal. [26]
Russia and the United States signed the Strategic Offensive Reductions Treaty in Moscow on 24 May 2002. This treaty mandates cuts in deployed strategic nuclear warheads, but without actually mandating cuts to total stockpiled warheads, and without any mechanism for enforcement.
On June 13, 2002, the US withdrew from ABM (having given notice 6 months earlier). The next day, Russia responded by declaring it would no longer abide by the START II treaty, which had not entered into force. [27]
In interviews with Oliver Stone in 2017, Russian president Vladimir Putin said that in trying to persuade Russia to accept US withdrawal from the treaty, both Bill Clinton and George W. Bush had tried, without evidence, to convince him of an emerging nuclear threat from Iran. [28]
On 1 March 2018, Russian president Vladimir Putin, in an address to the Federal Assembly, announced the development of a series of technologically new "super weapons" in response to U.S. withdrawal from the ABM Treaty. [29] [30] [31] His statements were referred to by an anonymous US official under the Trump administration as largely "boastful untruths". [32] He said that the U.S. decision triggered the Russian Government to order an increase in Russia's nuclear capabilities, designed to counterbalance U.S. ones. [33]
In 2021, Putin cited U.S. withdrawal among his grievances against the West: "We tried to partner with the West for many years, but the partnership was not accepted, it didn't work," often citing it as one of America's great post-Cold War sins. [34]
An anti-ballistic missile (ABM) is a surface-to-air missile designed to counter ballistic missiles. Ballistic missiles are used to deliver nuclear, chemical, biological, or conventional warheads in a ballistic flight trajectory. The term "anti-ballistic missile" is a generic term for a system designed to intercept and destroy any type of ballistic threat; however, it is commonly used for systems specifically designed to counter intercontinental ballistic missiles (ICBMs).
An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than 5,500 kilometres (3,400 mi), primarily designed for nuclear weapons delivery. Conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs. Most modern designs support multiple independently targetable reentry vehicle (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. The United States, Russia, China, France, India, the United Kingdom, Israel, and North Korea are the only countries known to have operational ICBMs. Pakistan is the only nuclear-armed state that does not possess ICBMs.
The Strategic Defense Initiative (SDI), derisively nicknamed the Star Wars program, was a proposed missile defense system intended to protect the United States from attack by ballistic nuclear missiles. The program was announced in 1983, by President Ronald Reagan. Reagan called for a system that would render nuclear weapons obsolete, and to end the doctrine of mutual assured destruction (MAD), which he described as a "suicide pact". Elements of the program reemerged in 2019 under the Space Development Agency (SDA).
A multiple independently targetable reentry vehicle (MIRV) is an exoatmospheric ballistic missile payload containing several warheads, each capable of being aimed to hit a different target. The concept is almost invariably associated with intercontinental ballistic missiles carrying thermonuclear warheads, even if not strictly being limited to them. An intermediate case is the multiple reentry vehicle (MRV) missile which carries several warheads which are dispersed but not individually aimed. All nuclear-weapon states except Pakistan and North Korea are currently confirmed to have deployed MIRV missile systems. Israel is suspected to possess or be in the process of developing MIRVs.
The Strategic Arms Limitation Talks (SALT) were two rounds of bilateral conferences and corresponding international treaties involving the United States and the Soviet Union. The Cold War superpowers dealt with arms control in two rounds of talks and agreements: SALT I and SALT II.
National missile defense (NMD) refers to the nationwide antimissile program the United States has had under development since the 1990s. After the renaming in 2002, the term now refers to the entire program, not just the ground-based interceptors and associated facilities.
START I was a bilateral treaty between the United States and the Soviet Union on the reduction and the limitation of strategic offensive arms. The treaty was signed on 31 July 1991 and entered into force on 5 December 1994. The treaty barred its signatories from deploying more than 6,000 nuclear warheads and a total of 1,600 intercontinental ballistic missiles (ICBMs) and bombers.
The Intermediate-Range Nuclear Forces Treaty was an arms control treaty between the United States and the Soviet Union. US President Ronald Reagan and Soviet General Secretary Mikhail Gorbachev signed the treaty on 8 December 1987. The US Senate approved the treaty on 27 May 1988, and Reagan and Gorbachev ratified it on 1 June 1988.
The nuclear arms race was an arms race competition for supremacy in nuclear warfare between the United States, the Soviet Union, and their respective allies during the Cold War. During this same period, in addition to the American and Soviet nuclear stockpiles, other countries developed nuclear weapons, though no other country engaged in warhead production on nearly the same scale as the two superpowers.
START II was a bilateral treaty between the United States and Russia on the Reduction and Limitation of Strategic Offensive Arms. It was signed by US President George H. W. Bush and Russian President Boris Yeltsin on 3 January 1993, banning the use of multiple independently targetable re-entry vehicles (MIRVs) on intercontinental ballistic missiles (ICBMs). Hence, it is often cited as the De-MIRV-ing Agreement.
A Fractional Orbital Bombardment System (FOBS) is a warhead delivery system that uses a low Earth orbit towards its target destination. Just before reaching the target, it deorbits through a retrograde engine burn.
Missile defense is a system, weapon, or technology involved in the detection, tracking, interception, and also the destruction of attacking missiles. Conceived as a defense against nuclear-armed intercontinental ballistic missiles (ICBMs), its application has broadened to include shorter-ranged non-nuclear tactical and theater missiles.
The Safeguard Program was a U.S. Army anti-ballistic missile (ABM) system designed to protect the U.S. Air Force's Minuteman ICBM silos from attack, thus preserving the US's nuclear deterrent fleet. It was intended primarily to protect against the very small Chinese ICBM fleet, limited Soviet attacks and various other limited-launch scenarios. A full-scale attack by the Soviets would easily overwhelm it. It was designed to allow gradual upgrades to provide similar lightweight coverage over the entire United States over time.
Brilliant Pebbles was a ballistic missile defense (BMD) system proposed by Lowell Wood and Edward Teller of the Lawrence Livermore National Laboratory (LLNL) in 1987, near the end of the Cold War. The system would consist of thousands of small satellites, each with missiles similar to conventional heat seeking missiles, placed in low Earth orbit constellations so that hundreds would be above the Soviet Union at all times. If the Soviets launched their ICBM fleet, the pebbles would detect their rocket motors using infrared seekers and collide with them. Because the pebble strikes the ICBM before the latter could release its warheads, each pebble could destroy several warheads with one shot.
The Reykjavík Summit was a summit meeting between U.S. President Ronald Reagan and General Secretary of the Communist Party of the Soviet Union Mikhail Gorbachev, held in Reykjavík, Iceland, on 11–12 October 1986. The talks collapsed at the last minute, but the progress that had been achieved eventually resulted in the 1987 Intermediate-Range Nuclear Forces Treaty between the United States and the Soviet Union.
The militarisation of space involves the placement and development of weaponry and military technology in outer space. The early exploration of space in the mid-20th century had, in part, a military motivation, as the United States and the Soviet Union used it as an opportunity to demonstrate ballistic-missile technology and other technologies having the potential for military application. Outer space has since been used as an operating location for military spacecraft such as imaging and communications satellites, and some ballistic missiles pass through outer space during their flight. As of 2018, known deployments of weapons stationed in space include only the Almaz space-station armament and pistols such as the TP-82 Cosmonaut survival pistol.
Nuclear weapons delivery is the technology and systems used to place a nuclear weapon at the position of detonation, on or near its target. Several methods have been developed to carry out this task.
Sentry, known for most of its lifetime as LoADS for Low Altitude Defense System, was a short-range anti-ballistic missile (ABM) design made by the US Army during the 1970s. It was proposed as a defensive weapon that would be used in concert with the MX missile, a US Air Force ICBM that was under development.
Swarmjet was an extremely short-range single-shot anti-ballistic missile (ABM) system proposed by the United States as a defensive measure during the development of the MX missile. It consisted of a launcher containing thousands of spin-stabilized unguided rockets that would be fired into the path of an enemy nuclear warhead, enough that it would be highly likely one of the rockets would hit the warhead and destroy it.
Project BAMBI was a project as part of the United States national missile defense.
Each site would consist of 100 ABMs, or a total of 200 ABMs for each country
The dramatic proliferation of warheads allowed by MIRV ensured that even an extensive ABM effort could not limit the destructiveness of an American retaliatory strike
The missiles are considered particularly effective, since they send 50 warheads over their target area, 40 of which are decoys designed to outwit sophisticated missile defence systems of the kind planned by the Bush administration.
Although Kosygin rejected this reasoning at Glassboro, U.S.-Soviet negotiations in the Strategic Arms Limitation Talks (SALT) led in 1972 to the signing of the ABM Treaty that limited both sides to modest missile defense.
Let there be no mistake about this in Washington. It is time they stopped devising one option after another in the search of the best ways of unleashing nuclear war in the hope of winning it. Engaging in this is not just irresponsible, it is insane.
Although the ABM Treaty continues in force, it nevertheless has become necessary to reach agreement as to which New Independent States (NIS) would collectively assume the rights and obligations of the USSR under the Treaty.
