Nuclear Free World Policy
These countries are weary of nuclear weapons’ deployment above everything else. Although 8 states are exempted from ban on nuclear weapons, 5 nations retain a de jure status of a “nuclear weapon state.” These states are the United States of America, the United Kingdom, the People’s Republic of China, France and Russia—all of whom had already tested nuclear weapons before the NPT was signed. NWS’s right to possess a nuclear arsenal is countered by Article VI of the treaty, which says that they have a legal obligation to eventually disarm. They also criticized NWS countries for failing to meet their obligation to disarm, in addition to criticizing the 3 states non-signatory nuclear weapons-capable states (which are considered de facto nuclear weapons states). This was stated in point 4 of the Joint Declaration of 1998:
2010 NPT Review Conference
The Nuclear Nonproliferation Treaty (NPT), which entered into force in 1970, recognizes five countries as nuclear-weapon states (the United States, Russia, the United Kingdom, France, and China), who commit to pursue disarmament, and the right of other signatories to use nuclear technology for peaceful purposes, conditional upon their non-acquisition of nuclear weapons. Its ratification is nearly universal because it is adhered by 189 states, including five nuclear-weapon states, with the exception of Israel, India, and Pakistan. North Korea left the NPT and tested its first nuclear weapon in 2006.
