Text of the INF Treaty

The Intermediate-Range Nuclear Forces Treaty (INF Treaty, formally Treaty Between the United States of America and the Union of Soviet Socialist Republics on the Elimination of Their Intermediate-Range and Shorter-Range Missiles; Russian: Договор о ликвидации ракет средней и меньшей дальности / ДРСМД, Dogovor o likvidatsiy raket sredney i menshey dalnosti / DRSMD) was an arms control treaty between the United States and the Soviet Union (and its successor state, the Russian Federation). U.S. President Ronald Reagan and Soviet General Secretary Mikhail Gorbachev signed the treaty on 8 December 1987.[1][2] The United States Senate approved the treaty on 27 May 1988, and Reagan and Gorbachev ratified it on 1 June 1988.[2][3]

The INF Treaty eliminated all of two nations' land-based ballistic missiles, cruise missiles, and missile launchers with ranges of 500–1,000 kilometers (310–620 mi) (short medium-range) and 1,000–5,500 km (620–3,420 mi) (intermediate-range). The treaty did not apply to air- or sea-launched missiles.[4][5] By May 1991, the nations had eliminated 2,692 missiles, followed by 10 years of on-site verification inspections.[6]

President Donald Trump announced on 20 October 2018 that he was withdrawing the U.S. from the treaty, citing Russian non-compliance.[7] The Western press has been dismissive of Russian claims that U.S. missile defense in Eastern Europe, ostensibly meant to intercept missiles from Iran, presents a formidable offensive force near Russian borders. The Bulletin of the Atomic Scientists published a report in February 2019, using publicly available documents, on how the Aegis-based missile defense installations in Poland and Romania are not capable of providing missile defense against Iran due to the limited range of the Aegis radar, but retain offensive capabilities that are in violation of the INF.[8]

The U.S. formally suspended the treaty on 1 February 2019,[9] and Russia did so the following day.[10]

Background

In March 1976, the Soviet Union first deployed the RSD-10 Pioneer (called SS-20 Saber in the West) in its European territories, a mobile, concealable intermediate-range ballistic missile (IRBM) with a multiple independently targetable reentry vehicle (MIRV) containing three nuclear 150-kiloton warheads.[11] The SS-20's range of 4,700–5,000 kilometers (2,900–3,100 mi) was great enough to reach Western Europe from well within Soviet territory; the range was just below the SALT II minimum range for an intercontinental ballistic missile, 5,500 km (3,400 mi).[12][13][14] The SS-20 replaced aging Soviet systems of the SS-4 Sandal and SS-5 Skean, which were seen to pose a limited threat to Western Europe due to their poor accuracy, limited payload (one warhead), lengthy preparation time, difficulty in being concealed, and immobility (thus exposing them to pre-emptive NATO strikes ahead of a planned attack).[15] Whereas the SS-4 and SS-5 were seen as defensive weapons, the SS-20 was seen as a potential offensive system.[16]

The US, then under President Jimmy Carter, initially considered its strategic nuclear weapons and nuclear-capable aircraft to be adequate counters to the SS-20 and a sufficient deterrent against possible Soviet aggression. In 1977, however, Chancellor Helmut Schmidt of West Germany argued in a speech that a Western response to the SS-20 deployment should be explored, a call which was echoed by NATO, given a perceived Western disadvantage in European nuclear forces.[14] Leslie H. Gelb, the US Assistant Secretary of State, later recounted that Schmidt's speech pressured the US into developing a response.[17]

SS-20 launchers

On 12 December 1979, following European pressure for a response to the SS-20, Western foreign and defense ministers meeting in Brussels made the NATO Double-Track Decision.[14] The ministers argued that the Warsaw Pact had "developed a large and growing capability in nuclear systems that directly threaten Western Europe": "theater" nuclear systems (i.e., tactical nuclear weapons[18]). In describing this "aggravated" situation, the ministers made direct reference to the SS-20 featuring "significant improvements over previous systems in providing greater accuracy, more mobility, and greater range, as well as having multiple warheads". The ministers also attributed the altered situation to the deployment of the Soviet Tupolev Tu-22M strategic bomber, which they believed to display "much greater performance" than its predecessors. Furthermore, the ministers expressed concern that the Soviet Union had gained an advantage over NATO in "Long-Range Theater Nuclear Forces" (LRTNF), and also significantly increased short-range theater nuclear capacity.[19]

To address these developments, the ministers adopted two policy "tracks". One thousand theater nuclear warheads, out of 7,400 such warheads, would be removed from Europe and the US would pursue bilateral negotiations with the Soviet Union intended to limit theater nuclear forces. Should these negotiations fail, NATO would modernize its own LRTNF, or intermediate-range nuclear forces (INF), by replacing US Pershing 1a missiles with 108 Pershing II launchers in West Germany and deploying 464 BGM-109G Ground Launched Cruise Missiles (GLCMs) to Belgium, Italy, the Netherlands, and the United Kingdom beginning in December 1983.[13][20][21][22]

Negotiations

Early negotiations: 1981–1983

The Soviet Union and United States agreed to open negotiations and preliminary discussions, named the Preliminary Intermediate-Range Nuclear Forces Talks,[13] which began in Geneva in October 1980. On 20 January 1981, Ronald Reagan was sworn into office as President after defeating Jimmy Carter in an election. Formal talks began on 30 November 1981, with the US then led by Ronald Reagan and the Soviet Union by Leonid Brezhnev. The core of the US negotiating position reflected the principles put forth under Carter: any limits placed on US INF capabilities, both in terms of "ceilings" and "rights", must be reciprocated with limits on Soviet systems. Additionally, the US insisted that a sufficient verification regime be in place.[23]

Paul Nitze, a longtime hand at defense policy who had participated in the Strategic Arms Limitation Talks (SALT), led the US delegation after being recruited by Secretary of State Alexander Haig. Though Nitze had backed the first SALT treaty, he opposed SALT II and had resigned from the US delegation during its negotiation. Nitze was also then a member of the Committee on the Present Danger, a firmly anti-Soviet group composed of neoconservatives and conservative Republicans.[17][24] Yuli Kvitsinsky, the well-respected second-ranking official at the Soviet embassy in West Germany, headed the Soviet delegation.[16][25][26][27]

Paul Nitze, 1983

On 18 November 1981, shortly before the beginning of formal talks, Reagan made the Zero Option proposal (or the "zero-zero" proposal).[28] The plan called for a hold on US deployment of GLCM and Pershing II systems, reciprocated by Soviet elimination of its SS-4, SS-5, and SS-20 missiles. There appeared to be little chance of the Zero Option being adopted, but the gesture was well received in the European public. In February 1982, US negotiators put forth a draft treaty containing the Zero Option and a global prohibition on intermediate- and short-range missiles, with compliance ensured via a stringent, though unspecific, verification program.[25]

Opinion within the Reagan administration on the Zero Option was mixed. Richard Perle, then the Assistant Secretary of Defense for Global Strategic Affairs, was the architect of the plan. Secretary of Defense Caspar Weinberger, who supported a continued US nuclear presence in Europe, was skeptical of the plan, though eventually accepted it for its value in putting the Soviet Union "on the defensive in the European propaganda war". Reagan later recounted that the "zero option sprang out of the realities of nuclear politics in Western Europe".[28] The Soviet Union rejected the plan shortly after the US tabled it in February 1982, arguing that both the US and Soviet Union should be able to retain intermediate-range missiles in Europe. Specifically, Soviet negotiators proposed that the number of INF missiles and aircraft deployed in Europe by one side be capped at 600 by 1985 and 300 by 1990. Concerned that this proposal would force the US to withdraw aircraft from Europe and not deploy INF missiles, given US cooperation with existing British and French deployments, the US proposed "equal rights and limits"—the US would be permitted to match Soviet SS-20 deployments.[25]

Between 1981 and 1983, US and Soviet negotiators gathered for six rounds of talks, each two months in length—a system based on the earlier SALT talks.[25] The US delegation was composed of Nitze, General William F. Burns of the Joint Chiefs of Staff, Thomas Graham of the Arms Control and Disarmament Agency (ACDA), and officials from the US Department of State, Office of the Secretary of Defense, and US National Security Council. Colonel Norman Clyne, a SALT participant, served as Nitze's chief of staff.[16][29]

There was little convergence between the two sides over these two years. A U.S. effort to separate the question of nuclear-capable aircraft from that of intermediate-range missiles successfully focused attention on the latter, but little clear progress on the subject was made. In the summer of 1982, Nitze and Kvitsinsky took a "walk in the woods" in the Jura Mountains, away from formal negotiations in Geneva, in an independent attempt to bypass bureaucratic procedures and break the negotiating deadlock.[30][16][31] Nitze later said that his and Kvitsinsky's goal was to agree to certain concessions that would allow for a summit meeting between Brezhnev and Reagan later in 1982.[32]

Nitze's offer to Kvitsinsky was that the US would forego deployment of the Pershing II and continue deployment of GLCMs, but limited to 75 missile launchers. The Soviet Union, in return, would also have to limit itself to 75 intermediate-range missile launchers in Europe and 90 in Asia. Due to each GLCM launcher containing four GLCMs and each SS-20 launcher containing three warheads, such an agreement would have resulted in the US having 75 more intermediate-range warheads in Europe than the Soviet Union, though SS-20s were seen as more advanced and maneuverable than GLCMs. While Kvitsinsky was skeptical that the plan would be well received in Moscow, Nitze was optimistic about its chances in Washington.[32] The deal ultimately found little traction in either capital. In the US, the Office of the Secretary of Defense opposed Nitze's proposal, as it opposed any proposal that would allow the Soviet Union to deploy missiles to Europe while blocking US deployments. Nitze's proposal was relayed by Kvitsinsky to Moscow, where it was also rejected. The plan accordingly was never introduced into formal negotiations.[30][16]

Thomas Graham, a US negotiator, later recalled that Nitze's "walk in the woods" proposal was primarily of Nitze's own design and known beforehand only to William F. Burns, another arms control negotiator and representative of the Joint Chiefs of Staff (JCS), and Eugene V. Rostow, the director of the Arms Control and Disarmament Agency. In a National Security Council following the Nitze-Kvitsinsky walk, the proposal was received positively by the JCS and Reagan. Following protests by Richard Perle, working within the Office of the Secretary of Defense, Reagan informed Nitze that he would not back the plan. The State Department, then led by Alexander Haig, also indicated that it would not support Nitze's plan and preferred a return to the Zero Option proposal.[16][31][32] Nitze argued that one positive consequence of the walk in the woods was that the European public, which had doubted US interest in arms control, became convinced that the US was participating in the INF negotiations in good faith.[32]

In early 1983, US negotiators indicated that they would support a plan beyond the Zero Option if the plan established equal rights and limits for the US and Soviet Union, with such limits valid worldwide, and excluded British and French missile systems (as well as those of any other third party). As a temporary measure, the US negotiators also proposed a cap of 450 deployed INF warheads around the world for both the US and Soviet Union. In response, Soviet negotiators expressed that a plan would have to block all US INF deployments in Europe, cover both missiles and aircraft, include third parties, and focus primarily on Europe for it to gain Soviet backing. In the fall of 1983, just ahead of the scheduled deployment of US Pershing IIs and GLCMs, the US lowered its proposed limit on global INF deployments to 420 missiles, while the Soviet Union proposed "equal reductions": if the US cancelled the planned deployment of Pershing II and GLCM systems, the Soviet Union would reduce its own INF deployment by 572 warheads. In November 1983, after the first Pershing IIs arrived in West Germany, the Soviet Union walked out of negotiations, as it had warned it would do should the US missile deployments occur.[33]

Restarted negotiations: 1985–1987

Reagan and Gorbachev shake hands after signing the INF Treaty ratification during the Moscow Summit on 1 June 1988.

British Prime Minister Margaret Thatcher played a key role in brokering the negotiations between Reagan and Gorbachev in 1986–1987.[34]

In March 1986, negotiations between the US and the Soviet Union resumed, covering not only the INF issue, but also separate discussions on strategic weapons (START I) and space issues (Nuclear and Space Talks). In late 1985, both sides were moving towards limiting INF systems in Europe and Asia. On 15 January 1986, Gorbachev announced a Soviet proposal for a ban on all nuclear weapons by 2000, which included INF missiles in Europe. This was dismissed by the US and countered with a phased reduction of INF launchers in Europe and Asia to none by 1989. There would be no constraints on British and French nuclear forces.[35]

A series of meetings in August and September 1986 culminated in the Reykjavík Summit between Reagan and Gorbachev on 11 October 1986. Both agreed in principle to remove INF systems from Europe and to equal global limits of 100 INF missile warheads. Gorbachev also proposed deeper and more fundamental changes in the strategic relationship. More detailed negotiations extended throughout 1987, aided by the decision of West German Chancellor Helmut Kohl in August to unilaterally remove the joint US-West German Pershing 1a systems. Initially, Kohl had opposed the total elimination of the Pershing Missiles, claiming that such a move would increase his nation's vulnerability to an attack by Warsaw Pact Forces.[36] The treaty text was finally agreed in September 1987. On 8 December 1987, the Treaty was officially signed by President Reagan and General Secretary Gorbachev at a summit in Washington and ratified the following May in a 93-5 vote by the United States Senate.[37][38]

Contents

The treaty[39] prohibits both parties from possessing, producing or flight-testing ground-launched ballistic and cruise missiles with ranges of 500-5,500km. Possessing or producing ground-based launchers of those missiles is also prohibited. The ban extends to weapons with both nuclear and conventional warheads, but does not cover air-delivered or sea-based missiles.

Existing weapons had to be destroyed, and a protocol for mutual inspection was agreed upon.

Each party has the right to withdraw from the treaty with six months' notice, "if it decides that extraordinary events related to the subject matter of this Treaty have jeopardized its supreme interests".

By the treaty's deadline of 1 June 1991, a total of 2,692 of such weapons had been destroyed, 846 by the US and 1,846 by the Soviet Union.[40]

As provided by the treaty, onsite inspections ended in 2001. After that time, compliance was checked primarily by satellites.[41]

Affected weapons

The following specific missiles, their launcher systems and their transporter vehicles were destroyed:[42]
