The decision on which countries can possess nuclear weapons is largely influenced by international treaties and agreements, primarily the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Under the NPT, five countries— the United States, Russia, China, France, and the United Kingdom—are recognized as nuclear-armed states, while other countries commit not to develop or acquire nuclear weapons. Ultimately, enforcement and compliance are overseen by international bodies like the International Atomic Energy Agency (IAEA) and the United Nations, but geopolitical dynamics also play a significant role in nuclear proliferation discussions.
