The Nuclear Non-Proliferation Treaty (NPT) is an international agreement aimed at preventing the spread of nuclear weapons. Established in 1968, it has three main objectives: to promote the peaceful use of nuclear energy, to prevent the proliferation of nuclear weapons, and to pursue nuclear disarmament. The treaty is a cornerstone of global efforts to maintain international security. The NPT is supported by 191 countries, making it one of the most widely adhered-to arms control agreements. Five recognized nuclear-armed states under the treaty are the United States, Russia, China, France, and the United Kingdom, known as the P5. Other nations are encouraged to forgo developing nuclear weapons in exchange for access to peaceful nuclear technology.
