Nuclear treaties are formal agreements between countries aimed at regulating the development, testing, and proliferation of nuclear weapons. These treaties seek to promote global security and prevent the spread of nuclear arms, ensuring that nations adhere to specific guidelines regarding their nuclear capabilities. One of the most significant nuclear treaties is the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), which encourages disarmament and the peaceful use of nuclear energy. Other agreements, like the Comprehensive Nuclear-Test-Ban Treaty (CTBT), focus on banning nuclear tests altogether, further contributing to international efforts to reduce nuclear threats.
