The global effort towards nuclear disarmament and non-proliferation is primarily governed by a complex web of international treaties. These agreements aim to prevent the spread of nuclear weapons and ultimately achieve a world free of them.
However, the existing framework has faced significant criticism. A central point of contention is its perceived discriminatory nature, which creates a stark divide between nuclear-armed states and non-nuclear states.
This criticism is most often directed at the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), which recognizes five states as legitimate nuclear weapon states while prohibiting others from acquiring them.
The Comprehensive Nuclear-Test-Ban Treaty (CTBT) is a multilateral treaty that bans all nuclear explosions, whether for military or peaceful purposes, in any environment. Its primary objective is to curb the development of new nuclear weapons and the qualitative improvement of existing ones.
CTBT Status: The treaty was adopted by the United Nations General Assembly in 1996. However, it is not yet fully in force because it requires ratification by 44 specific states, eight of which (including India, Pakistan, China, Egypt, Iran, Israel, North Korea, and the United States) have not yet ratified it.

TPNW Prohibitions: The treaty undertakes for states parties not to:
The TPNW entered into force on January 22, 2021. It is supported by a large number of non-nuclear weapon states and civil society organizations, but it is opposed by all nuclear weapon states and their allies, who argue it is not an effective path to disarmament.
