In November 1972, Washington and Moscow agreed to follow a FOLLOW-up contract of SALT I. SALT II, signed in June 1979, which limited U.S. and Soviet nuclear forces to 2,250 delivery vehicles (defined as ICBM silo, SLBM or heavy bombers) and implemented a multitude of additional restrictions for deployed strategic nuclear forces. The agreement would have forced the Soviets to reduce their troops by about 270 delivery vehicles, but U.S. forces were below limits and could even have been increased. However, President Jimmy Carter asked the Senate not to consider SALT II after the Soviet Union invaded Afghanistan in December 1979 for its advice and approval, and the treaty was not resumed. Washington and Moscow then pledged to abide by the terms of the agreement, although it did not enter into force. However, on May 26, 1986, President Ronald Reagan declared that future decisions on fundamental strategic forces would be based on the threat of Soviet forces and not on a “defective SALT II treaty.” START-I`s successor, Richard Nixon, also believed in SALT, and on November 17, 1969, formal discussions on SALT began in Helsinki, Finland. Over the next two and a half years, the two sides negotiated whether or not each nation should finalize its ABMs plans; Reviewing a contract And the United States feared that the Soviets would continue to build more submarine-launched ballistic missiles. Nixon and Soviet Secretary General Leonid Brezhnev signed the ABM Treaty and the SALT Interim Agreement on May 26, 1972 in Moscow. The Strategic Arms Reduction Treaty (START I), first proposed in the early 1980s by President Ronald Reagan and finally signed in July 1991, forced the United States and the Soviet Union to reduce their strategic arsenals to 1,600 delivery vehicles, which carried no more than 6,000 warheads in accordance with the rules of the agreement. The agreement required the destruction of surplus delivery vehicles, which were verified through an intrusive control system including on-site inspections, regular exchanges of information (including telemetry) and the use of national technical means (e.g. satellites).
The entry into force of the agreement was delayed for several years due to the collapse of the Soviet Union and subsequent efforts to de-incarcerate Ukraine, Kazakhstan and Belarus, returning their nuclear weapons to Russia and making it part of the non-proliferation and launch I agreements. Start I reductions were completed in December 2001 and the contract expired on December 5, 2009. START II The resulting complex of agreements (SALT I) were the most important were the Anti-Ballistic Missile Systems Treaty (ABM) and the Interim Agreement and Protocol on the Limitation of Strategic Offensive Weapons. Both were signed by President Richard M. Nixon for the United States and Leonid Brezhnev, General Secretary of the Communist Party of the Soviet Union, for the U.S.S.R. on May 26, 1972 at a summit in Moscow. Even after the Vladivostok agreements, the two nations were unable to resolve the other two outstanding issues of SALT I: the number of strategic bombers and the total number of warheads in each nation`s arsenal. The first was made more difficult by the Soviet Bomber Backfire, which American negotiators thought could reach the United States, but which the Soviets did not want to include in the SALT negotiations. Meanwhile, the Soviets tried unsuccessfully to limit the American use of cruise air missiles (ALCMs). The audit also divided the two nations, but they eventually agreed on the use of National Technical Means (NTM), including the collection of electronic signals known as telemetry and the use of photo recognition satellites. On June 17, 1979, Carter and Brezhnev signed the SALT II Treaty in Vienna. Salt II limited the total number of nuclear forces from both countries to 2,250 delivery vehicles and imposed numerous additional restrictions on core strategic forces, including MIRVs.
