Strategic Arms Limitation Talks were a series of bilateral conferences between the United States and the Soviet Union during the Cold War aimed at curtailing the arms race in strategic nuclear weapons. Initiated under President Lyndon B. Johnson and pursued vigorously by President Richard Nixon and his National Security Advisor Henry Kissinger, the negotiations sought to establish verifiable limits on the two superpowers' most dangerous weaponry. The talks produced two major agreements, SALT I and the unratified SALT II, which became cornerstones of the policy of détente and established frameworks for future arms control.

Background and origins

The impetus for the talks stemmed from the escalating and costly nuclear arms race following the Cuban Missile Crisis, which highlighted the perils of uncontrolled competition. Advances in technology, particularly the deployment of Anti-Ballistic Missile systems by both nations, threatened to destabilize the balance of terror embodied in the doctrine of Mutually Assured Destruction. Preliminary discussions began in 1967 under the Johnson administration, involving Secretary of Defense Robert McNamara, but were halted by the Soviet invasion of Czechoslovakia. The political landscape shifted with the election of Richard Nixon, who, with Henry Kissinger, prioritized strategic dialogue with Soviet Premier Leonid Brezhnev through the novel concept of linkage diplomacy.

SALT I (1969–1972)

The first round of negotiations opened in Helsinki in November 1969, with the U.S. delegation led by Gerard Smith of the Arms Control and Disarmament Agency. The talks occurred amid ongoing conflicts like the Vietnam War and were closely tied to other diplomatic efforts, including the Moscow Summit (1972). The primary outcomes were two linked agreements signed in Moscow in May 1972: the Anti-Ballistic Missile Treaty, which severely limited ABM systems, and the Interim Agreement on the Limitation of Strategic Offensive Arms. This interim pact froze the number of Intercontinental Ballistic Missile and Submarine-Launched Ballistic Missile launchers at existing levels for five years, though it did not limit Multiple Independently Targetable Reentry Vehicle technology.

SALT II (1972–1979)

Negotiations for a more comprehensive and permanent treaty began immediately after the signing of SALT I, aiming to replace the interim agreement. The talks proved protracted and complex, spanning the administrations of Richard Nixon, Gerald Ford, and Jimmy Carter. Major sticking points included limits on heavy ICBMs like the Soviet SS-18 Satan and on new U.S. systems like the Trident missile and Cruise missile. A breakthrough was finally achieved at the Vienna Summit (1979), where President Jimmy Carter and General Secretary Leonid Brezhnev signed the SALT II Treaty in June 1979.

Key provisions and treaties

The Anti-Ballistic Missile Treaty restricted each side to two ABM deployment areas, later reduced to one, effectively forbidding a nationwide defense. The SALT I Interim Agreement established numerical ceilings on launchers but was criticized for allowing qualitative improvements. The more elaborate SALT II Treaty established an aggregate ceiling of 2,400 strategic nuclear delivery vehicles for each side, with a sub-limit of 1,320 for MIRVed systems. It also included detailed verification protocols relying on National Technical Means, such as reconnaissance satellites, and banned the construction of new fixed ICBM launchers.

Impact and legacy

The talks significantly reduced tensions and institutionalized dialogue between the two superpowers, a central feature of the détente era. While critics, like Senator Henry M. Jackson, argued the treaties codified Soviet advantages, they established crucial precedents for verification and mutual limitation. The process fostered direct communication channels between Washington, D.C. and Moscow, arguably reducing the risk of miscalculation. The ABM Treaty in particular was hailed as a landmark for preserving strategic stability by preventing a defensive arms race.

Subsequent negotiations

Although the SALT II Treaty was never ratified by the United States Senate following the Soviet–Afghan War, both nations largely adhered to its terms. The framework directly paved the way for the next phase of arms control, the Strategic Arms Reduction Talks, which began under President Ronald Reagan. The START I treaty, signed in 1991 by President George H. W. Bush and President Mikhail Gorbachev, achieved the actual reductions in warheads that the earlier talks had sought to limit, carrying forward the diplomatic legacy established during the Strategic Arms Limitation Talks.
