The resulting set of agreements (SALT I) included the Ballistic Missile Systems (ABM) Treaty 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. Russia denies violating the agreement and has expressed its own concerns about its compliance by Washington. Moscow has accused the United States of establishing an anti-missile launch system in Europe, which could also be used to fire cruise missiles, using targets for anti-missile tests similar to those of medium-range missiles banned under the CFI treaty, and manufacturing armed drones equivalent to cruise missiles launched on the ground. On October 20, 2018, President Donald Trump announced his intention to „end“ the agreement, citing Russia`s non-compliance and concerns about China`s missiles, and on December 4, Foreign Minister Mike Pompeo declared Russia a „essential violation“ of the treaty. On February 2, the Trump administration formally informed other states parties that it was suspending both its treaty obligations and would leave the agreement in six months, in accordance with the terms of the treaty, and that it would „end“ the agreement unless Russia returned to respect by eliminating its ground-launched 9M729 missiles. Since the 1960s, the United States and Russia have been able to prioritize bilateral negotiations on nuclear arms control. Even in times of conflict and tension, both countries know that cooperation in reducing nuclear security and risks is a matter of life and death. However, this history of arms control diplomacy has been put at risk in recent times.
In August 1972, the U.S. Senate approved the agreements by an overwhelming majority. Salt-I, as we have learned, served as the basis for all the discussions on weapons limitation that followed. New START works. The treaty expires in February 2021 and Russia and the United States must prioritize the renewal of the treaty. Without New START, the years of U.S.-Russian cooperation on nuclear weapons reduction, as we have seen here, would be lost. There would be no more security slides in a nuclear arms race. Add your name here using New START.
It was the first agreement between the United States and the USSR that limited and restricted their nuclear weapons systems. Negotiations began in November 1969 in Helsinki, Finland.  SALT I resulted in the anti-ballistic missile treaty and an interim agreement between the two countries. Although SALT II reached an agreement in 1979, the U.S. Senate decided not to ratify the treaty in response to the Soviet war in Afghanistan, which took place later that year. Nor has the Soviet legislature ratified it. The agreement expired on December 31, 1985 and was not renewed. The salt-II debate in the U.S. Congress lasted for months.
However, in December 1979, the Soviets launched an invasion of Afghanistan. The Soviet attack killed virtually every chance of going through SALT-II, and Carter made sure of that by withdrawing the Treaty from the Senate in January 1980.
