In January 2010 eight states—the United States, the Russian Federation, the United Kingdom, France, China, India, Pakistan and Israel—possessed more than 7500 operational nuclear weapons. If all nuclear warheads are counted, including operational warheads, spares, those in both active and inactive storage, and intact warheads scheduled for dismantlement, these states together possessed a total of more than 22 000 warheads.
The five legally recognized nuclear weapon states, as defined by the 1968 Non-Proliferation Treaty (NPT)—China, France, Russia, the United States and the United Kingdom—are either deploying new nuclear weapon systems or have announced their intention to do so; none appears to be prepared to give up their nuclear arsenals in the foreseeable future.
India and Pakistan, which along with Israel are de facto nuclear weapon states outside the NPT, continue to develop new missile systems that are capable of delivering nuclear weapons and are also expanding their capacities to produce fissile material. Israel appears to be waiting to assess how the situation with Iran’s nuclear programme develops. North Korea is believed to have produced enough plutonium for a small number of nuclear warheads, but it is unknown whether it has operational weapons.
