Nuclear arms control refers to international efforts to limit the development, testing, and deployment of nuclear weapons. This is achieved through treaties and agreements between countries, aimed at reducing the risk of nuclear conflict and promoting global security. Key treaties include the Nuclear Non-Proliferation Treaty (NPT) and the Strategic Arms Reduction Treaty (START). These agreements often involve measures such as verification processes, inspections, and commitments to disarmament. Countries participating in nuclear arms control seek to prevent the spread of nuclear weapons to additional states and to encourage responsible behavior among nuclear-armed nations, fostering a safer world for all.
