The 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 disarmament, to prevent the proliferation of nuclear weapons, and to encourage the peaceful use of nuclear energy. Countries that join the treaty commit to not developing or acquiring nuclear weapons. The NPT is supported by 191 countries, making it one of the most widely adhered-to arms control agreements. However, five nations—United States, Russia, China, France, and United Kingdom—are recognized as nuclear-armed states under the treaty. The NPT plays a crucial role in global security and stability.
