What term refers to countries' commitments to not spread nuclear weapons technology?

The term that refers to countries' commitments to not spread nuclear weapons technology is nuclear non-proliferation. This concept primarily revolves around preventing the increase in the number of states that possess nuclear weapons and ensuring that nations with nuclear capabilities do not transfer these weapons or the means to produce them to others.

Nuclear non-proliferation agreements, such as the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), are designed to promote disarmament, prevent the spread of nuclear weapons, and promote cooperation in the peaceful use of nuclear energy. This approach is crucial for global security, as it aims to reduce the risk of nuclear conflict and promote stability among nations.

Other terms like nuclear regulation and nuclear treaties may encompass broader legal frameworks and agreements but do not specifically highlight the commitment to prevent the spread of nuclear weapons technology in the same dedicated way that nuclear non-proliferation does. Nuclear deterrence, on the other hand, refers to the strategy of preventing aggression by the threat of retaliatory nuclear strikes, which is a different concept altogether.
