Mutual agreements to stop nuclear weapons are vital international efforts aimed at preventing, reducing, or eliminating the threat posed by nuclear weapons. These agreements are essential for fostering a global environment of peace, stability, and security. Here are some types of mutual agreements to stop nuclear weapons: 1. Nuclear Non-Proliferation Treaty (NOT): The NOT is a landmark international treaty formulated in 1968. It commits its signatory nations to prevent the spread of nuclear weapons, promote disarmament, and facilitate the peaceful use of nuclear energy. The NOT has been ratified by nearly all countries worldwide, making it the cornerstone of nuclear non-proliferation efforts. 2. Treaty on the Prohibition of Nuclear Weapons (TPN): Adopted by the United Nations General Assembly in 2017, the TPN provides a comprehensive framework for the total elimination of nuclear weapons. This treaty prohibits the development, testing, production, stockpiling, and use of nuclear weapons and calls for their complete elimination. It is considered a crucial step towards achieving a world free of nuclear weapons. 3. Strategic Arms Reduction Treaty (START): START agreements are bilateral accords between nuclear-armed states, primarily the United States and Russia. These agreements aim to limit and reduce the deployment of strategic nuclear weapons. Through various START iterations, the countries have significantly reduced their nuclear arsenals, fostering trust and stability. 4. Comprehensive Nuclear-Test-Ban Treaty (CTBT): CTBT is an international treaty prohibiting all nuclear weapon test explosions. Under this agreement, signatory nations commit to banning any nuclear tests, whether for military or civilian purposes. Although the treaty is not yet in force due to a few outstanding ratification, it serves as a valuable normative instrument against nuclear testing. 5. Joint Comprehensive Plan of Action (JC POA): The JC POA, also known as the Iran Nuclear Deal, was signed in 2015 between Iran and the P5+1 countries (United States, China, Russia, United Kingdom, France, and Germany). This agreement aimed to curb Iran's nuclear program and ensure its peaceful nature through rigorous inspections and limitations on uranium enrichment. While the U.S. withdrew from the deal in 2018, efforts continue to salvage and reinstate its provisions. These mutual agreements play a crucial role in global efforts to prevent the use, proliferation, and development of nuclear weapons. They highlight the commitment of nations to creating a safer world and demonstrate the collective determination to eliminate the catastrophic threat posed by nuclear warfare. Emphasizing trust, transparency, and cooperation, these agreements form the foundation for disarmament and non-proliferation efforts worldwide.
