Arms control refers to international agreements and treaties aimed at regulating the development, production, stockpiling, and use of weapons, particularly nuclear weapons. The goal is to reduce the risk of conflict and promote global security by limiting the number and types of arms that countries can possess. These agreements can take various forms, including bilateral treaties between two countries or multilateral agreements involving multiple nations. Examples include the Strategic Arms Reduction Treaty (START) and the Nuclear Non-Proliferation Treaty (NPT), which seek to prevent the spread of nuclear weapons and encourage disarmament among nations.
