At the beginning of 2007, the five nuclear weapon states recognized under the Non-Proliferation Treaty (NPT)—China, France, Russia, the United Kingdom and the USA—possessed a total of more than 26 000 nuclear warheads, including deployed weapons, spares and those in both active and inactive storage. All of these states, with the exception of the UK, had significant nuclear weapon modernization programmes under way. The UK announced its intention to replace its Trident submarine fleet with a new submarine-based nuclear deterrent beginning in the 2020s. India and Pakistan, which along with Israel are de facto nuclear weapon states outside the NPT, continued to develop new missile systems capable of delivering nuclear weapons. North Korea’s nuclear test explosion in October 2006 was widely believed to have been only a partial success and raised doubts about whether North Korea could manufacture operational nuclear weapons.
