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:
Pakistan and weapons of mass destruction
Pakistan is one of nine states to possess nuclear weapons. Pakistan began development of nuclear weapons in January 1972 under Prime Minister Zulfikar Ali Bhutto, who delegated the program to the Chairman of the Pakistan Atomic Energy Commission (PAEC) Munir Ahmad Khan with a commitment to having the bomb ready by the end of 1976. Since PAEC, consisting of over twenty laboratories and projects under nuclear engineer Munir Ahmad Khan, was falling behind schedule and having considerable difficulty producing fissile material, Abdul Qadeer Khan was brought from Europe by Bhutto at the end of 1974. As pointed out by Houston Wood, Professor of Mechanical & Aerospace Engineering, University of Virginia, Charlottesville, in his article on gas centrifuges, "The most difficult step in building a nuclear weapon is the production of fissile material"; as such, this work in producing fissile material as head of the Kahuta Project was pivotal to Pakistan developing the capability to detonate a nuclear bomb by the end of 1984.
