Nuclear agreements are treaties or pacts between countries that aim to regulate the development, testing, and proliferation of nuclear weapons. These agreements often include measures for disarmament, non-proliferation, and the peaceful use of nuclear energy. They are designed to promote international security and prevent the spread of nuclear weapons. One of the most notable nuclear agreements is the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), which was established in 1968. This treaty encourages countries to work towards disarmament and prevents nations without nuclear weapons from acquiring them. Other agreements may focus on specific countries or regions, addressing unique security concerns.
