Nuclear disarmament efforts refer to the international initiatives and treaties aimed at reducing, limiting, or completely eliminating nuclear weapons. These efforts are crucial for global peace and security, preventing the proliferation of these destructive devices.
The primary goal is to mitigate the existential threat posed by nuclear weapons, fostering a world free from their use or threat of use.
The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) is a landmark international treaty. It entered into force in 1970, becoming a cornerstone of the global non-proliferation regime.
Despite its widespread acceptance, the NPT has faced significant criticism. It is often perceived as discriminatory, creating a clear division between nuclear-armed states (NWS) and non-nuclear-weapon states (NNWS).
Critics argue that the treaty legitimizes the possession of nuclear weapons by five states while imposing strict obligations on others, leading to an unequal framework.
The Comprehensive Nuclear-Test-Ban Treaty (CTBT) is another pivotal instrument in nuclear disarmament. Its primary objective is to ban all nuclear explosions, regardless of their environment.
Although widely supported, the CTBT has not yet fully entered into force. This is due to the non-ratification by several key states whose adherence is necessary for its full legal effect.
UPSC often asks about the status of international treaties like CTBT and the reasons for their non-entry into force, especially concerning India's stance.
The Treaty on the Prohibition of Nuclear Weapons (TPNW) represents a more recent and robust effort towards complete nuclear disarmament. It was adopted in 2017 and entered into force in 2021.
The TPNW includes a comprehensive set of prohibitions on participating in any nuclear weapon activities. This makes it a significant step towards stigmatizing nuclear weapons.
Under the TPNW, states parties undertake not to develop, test, produce, acquire, possess, stockpile, use, or threaten to use nuclear weapons. It also prohibits assisting or encouraging any of these activities.
This treaty goes further than previous agreements by explicitly outlawing nuclear weapons, treating them similarly to chemical and biological weapons.
