Nuclear disarmament refers to the act of reducing or eliminating a state's nuclear weapons. It encompasses various measures, from arms control agreements to complete abolition.
Historically, efforts towards nuclear disarmament have been driven by the catastrophic potential of nuclear weapons and the desire for global peace and security. These efforts often involve complex negotiations and international treaties.
The primary goal is to prevent the spread of nuclear weapons (non-proliferation) and to ultimately achieve a world free of these destructive devices (disarmament).
The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) is a landmark international treaty aimed at preventing the spread of nuclear weapons and weapons technology.
It also promotes cooperation in the peaceful uses of nuclear energy and furthers the goal of achieving nuclear disarmament. It is considered the cornerstone of the global nuclear non-proliferation regime.
The NPT entered into force in 1970. It has been signed by 191 states, making it one of the most widely adhered-to arms control agreements.
The NPT is based on a three-pillar system: non-proliferation, disarmament, and the right to peacefully use nuclear technology.
The Strategic Arms Limitation Treaties (SALT) were two rounds of bilateral conferences and corresponding treaties between the United States and the Soviet Union.
These treaties aimed to curb the arms race in strategic ballistic missiles armed with nuclear weapons. They represented a significant step in managing Cold War tensions.
SALT I (signed 1972) froze the number of strategic ballistic missile launchers at existing levels and limited anti-ballistic missile (ABM) systems.
SALT II (signed 1979) set limits on strategic launchers and placed restrictions on the development of new types of strategic offensive weapons.
The Strategic Arms Reduction Treaties (START) were a series of bilateral treaties between the United States and the Soviet Union (later Russia) designed to reduce and limit strategic offensive arms.
These treaties went beyond simply limiting growth, aiming for actual reductions in deployed nuclear warheads and delivery vehicles.
START I (signed 1991) significantly reduced the number of deployed strategic nuclear warheads and bombs. It entered into force in 1994.
New START (signed 2010) further limited the number of deployed strategic nuclear warheads and bombs, as well as intercontinental ballistic missiles (ICBMs) and submarine-launched ballistic missiles (SLBMs).
The Comprehensive Nuclear-Test-Ban Treaty (CTBT) is a multilateral treaty that bans all nuclear explosions, for both civilian and military purposes, in all environments.
It aims to halt the development of new nuclear weapons and the qualitative improvement of existing ones, thereby contributing to nuclear disarmament and non-proliferation.
The CTBT was adopted by the United Nations General Assembly in 1996. It has been signed by 187 states and ratified by 178, but has not yet entered into force.
India has not signed or ratified the CTBT, citing concerns about its discriminatory nature and lack of a time-bound disarmament framework. This is a crucial point for UPSC Mains GS-II.
The Treaty on the Prohibition of Nuclear Weapons (TPNW), also known as the Nuclear Ban Treaty, is the first legally binding international agreement to comprehensively prohibit nuclear weapons.
It aims to achieve a total ban on nuclear weapons, leading towards their complete elimination. It was adopted by the UN General Assembly in 2017.
The TPNW entered into force on January 22, 2021. It prohibits states parties from developing, testing, producing, manufacturing, otherwise acquiring, possessing, or stockpiling nuclear weapons or other nuclear explosive devices.
Notably, none of the nuclear-weapon states recognized under the NPT, nor any NATO members, have signed or ratified the TPNW.
