The Anti-Ballistic Missile Treaty (1972–2002) 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. 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.
The Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT, is an international treaty whose objective is to prevent the spread of nuclear weapons and weapons technology, to promote cooperation in the peaceful uses of nuclear energy, and to further the goal of achieving nuclear disarmament and general and complete disarmament. Between 1965 and 1968, the treaty was negotiated by the Eighteen Nation Committee on Disarmament, a United Nations-sponsored organization based in Geneva, Switzerland.

The US Senate approved the treaty on 27 May 1988, and Reagan and Gorbachev ratified it on 1 June 1988.
The Russian Federation is known to possess or have possessed three types of weapons of mass destruction: nuclear weapons, biological weapons, and chemical weapons. It is one of the five nuclear-weapon states recognized under the Treaty on the Non-Proliferation of Nuclear Weapons.
The Treaty Between the United States of America and the Russian Federation on Strategic Offensive Reductions (SORT), also known as the Treaty of Moscow, was a strategic arms reduction treaty between the United States and Russia that was in force from June 2003 until February 2011 when it was superseded by the New START treaty.
The Union State, or Union State of Russia and Belarus, is a supranational union consisting of Belarus and Russia, with the stated aim of deepening the relationship between the two states through integration in economic and defence policy. Originally, the Union State aimed to create a confederation; however, both countries currently retain their independence. The Union State is based on a previous international treaty between Russia and Belarus made on 2 April 1997. Although it consists of only Russia and Belarus, other countries are allowed to join. The supranational union is ruled through the Supreme State Council and other governing bodies. As of 2023, the current president of the Supreme State Council of the Union is Alexander Lukashenko, who has held the position since 2000. The present goal of the Union State mainly focuses on economic integration, taxation, and integration of defence and intelligence apparatus.
As the collapse of the Soviet Union appeared imminent, the United States and their NATO allies grew concerned of the risk of nuclear weapons held in the Soviet republics falling into enemy hands. The Cooperative Threat Reduction (CTR) program was initiated by the Nunn–Lugar Act, which was authored and cosponsored by Sens. Sam Nunn (D-GA) and Richard Lugar (R-IN). According to the CTR website, the purpose of the CTR Program was originally "to secure and dismantle weapons of mass destruction and their associated infrastructure in former Soviet Union states." As the peace dividend grew old, an alternative 2009 explanation of the program was "to secure and dismantle weapons of mass destruction in states of the former Soviet Union and beyond". The CTR program funds have been disbursed since 1997 by the Defense Threat Reduction Agency (DTRA).
The original Treaty on Conventional Armed Forces in Europe (CFE) was negotiated and concluded during the last years of the Cold War and established comprehensive limits on key categories of conventional military equipment in Europe and mandated the destruction of excess weaponry. The treaty proposed equal limits for the two "groups of states-parties", the North Atlantic Treaty Organization (NATO) and the Warsaw Pact. In 2007, Russia "suspended" its participation in the treaty, and on 10 March 2015, citing NATO's alleged de facto breach of the Treaty, Russia formally announced it was "completely" halting its participation in it as of the next day. On 7 November 2023, Russia withdrew from the treaty, and in response the United States and its NATO allies suspended their participation in the treaty.
START III was a proposed bilateral arms control treaty between the United States and Russia that was meant to reduce the deployed nuclear weapons arsenals of both countries drastically and to continue the weapons reduction efforts that had taken place in the START I and START II negotiations. The framework for negotiations of the treaty began with talks in Helsinki between US President Bill Clinton and Russian President Boris Yeltsin in 1997. However, negotiations broke down, and the treaty was never signed.
The African Nuclear-Weapon-Free Zone Treaty, also known as the Treaty of Pelindaba, establishes a Nuclear-Weapon-Free Zone in Africa. The treaty was signed in 1996 and came into effect with the 28th ratification on 15 July 2009.
This timeline of nuclear weapons development is a chronological catalog of the evolution of nuclear weapons rooting from the development of the science surrounding nuclear fission and nuclear fusion. In addition to the scientific advancements, this timeline also includes several political events relating to the development of nuclear weapons. The availability of intelligence on recent advancements in nuclear weapons of several major countries is limited because of the classification of technical knowledge of nuclear weapons development.
Ukraine, a republic of the former Union of Soviet Socialist Republics (USSR) from 1922–1991, once hosted Soviet nuclear weapons and delivery systems on its territory. Together with Russia, Ukraine was a part of the former Soviet Union but its population voted overwhelmingly for independence in 1991, which ended any realistic chance of the Soviet Union staying together even on a limited scale.
The Budapest Memorandum on Security Assurances comprises three substantially identical political agreements signed at the OSCE conference in Budapest, Hungary, on 5 December 1994, to provide security assurances by its signatories relating to the accession of Belarus, Kazakhstan and Ukraine to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). The three memoranda were originally signed by three nuclear powers: the Russian Federation, the United Kingdom and the United States. China and France gave somewhat weaker individual assurances in separate documents.
Soviet Nuclear Threat Reduction Act of 1991, 22 U.S.C. § 2551, was chartered to amend the Arms Export Control Act enacting the transfer of Soviet military armaments and ordnances to NATO marking the conclusion of the Cold War. The Act sanctions the Soviet nuclear arsenal displacement shall be in conjunction with the implementation of the Treaty on Conventional Armed Forces in Europe. It funds the Nunn–Lugar Cooperative Threat Reduction program.
The National Nuclear Risk Reduction Center is part of the Russian Ministry of Defense, and known also as The Directorate for Control of Agreements' Implementation. It has counterpart in Washington D.C. in the United States Department of State. The main task is the organization of work on the implementation of agreements in the field of Arms reduction and implementation of all the international agreements which were signed by the Russian Ministry of Defence.
The Republic of Kazakhstan, once a republic of the Soviet Union, was a primary venue for Soviet nuclear weapon testing from 1949 until 1989. Following the collapse of the Union of Soviet Socialist Republics (USSR) in 1991, Kazakhstan became the fourth-largest nuclear power in the world and hosted a considerably large weapon support infrastructure due to its reliance on the Soviet nuclear program as a means to develop its own local economy. Besides the nuclear program, Kazakhstan was also a prominent site of Soviet programs of biological and chemical weapons.
The 1992 Agreement between the United States of America and the Russian Federation Concerning the Safe and Secure Transportation, Storage and Destruction of Weapons and the Prevention of Weapons Proliferation was instrumental for the release of funds pursuant to the Soviet Nuclear Threat Reduction Act of 1991. It was signed on 17 June 1992.
