P5 (Nuclear-Weapon States)

P5, or the Nuclear-Weapon States, refers to five countries officially recognized as possessing nuclear weapons: the United States, Russia, China, France, and the United Kingdom. These nations developed nuclear arsenals primarily during the Cold War and have since maintained them as strategic deterrents. The P5 plays a key role in global nuclear non-proliferation efforts, such as the Non-Proliferation Treaty (NPT), which aims to prevent the spread of nuclear weapons and promote disarmament. While these countries have acknowledged their nuclear status, the international community continues to work toward reducing nuclear arsenals and ensuring broader global security.
