Estimated worldwide nuclear stockpiles
The following is a list of nations that have admitted the possession of nuclear weapons, the approximate number of warheads under their control in 2002, and the year they tested their first weapon. This list is informally known in global politics as the "Nuclear Club". Note that with the exception of Russia and the United States (which have subjected their nuclear forces to independent verification under various treaties) these figures are estimates, in some cases quite unreliable estimates. Also, these figures represent total warheads possessed, rather than deployed. In particular, under the SORT treaty thousands of Russian and U.S. nuclear warheads are in inactive stockpiles awaiting processing. The radioactive fuel contained in the warheads can then be recycled for use in nuclear reactors that drive nuclear power plants and some military submarines and warships.From a high of 65,000 active weapons in 1985, there were about 20,000 active nuclear weapons in the world in 2002. Many of the "decommissioned" weapons were simply stored or partially dismantled, not destroyed.Webster, Paul (July/August 2003). "Just like old times," Bulletin of the Atomic Scientists 59:4: 30-35.

States that have tested a nuclear weapon
- The United States of America developed the first atomic weapons during World War II out of the fear that Nazi Germany would first develop them. It tested its first nuclear weapon in 1945 ("Trinity"), and remains the only country to have used nuclear weapons against another nation, during the atomic bombings of Hiroshima and Nagasaki (see: Manhattan Project). It was the first nation to develop the hydrogen bomb, testing it ("Ivy Mike") in 1952 and a deployable version in 1954 ("Castle Bravo").
- The USSR tested its first nuclear weapon ("Joe-1") in 1949, in a crash project developed partially with espionage obtained during and after World War II (see: Soviet atomic bomb project). The direct motivation for their weapons development was the development of a balance of power during the Cold War. It tested a primitive hydrogen bomb in 1953 ("Joe-4") and a megaton-range hydrogen bomb in 1955 ("RDS-37"). The Soviet Union also tested the most powerful explosive ever detonated by humans, ("Tsar Bomba"), which had a yield of 100 megatons, but was intentionally reduced to 50. After its dissolution in 1991, its weapons entered officially into the possession of Russia.
- The United Kingdom tested its first nuclear weapon ("Hurricane") in 1952, drawing largely on data gained while collaborating with the United States during the Manhattan Project. Its program was motivated to have an independent deterrence against the USSR, while also remaining relevant in Cold War Europe. It tested its first hydrogen bomb in 1957.
- France tested its first nuclear weapon in 1960, also as an independent deterrence and to retain perceived Cold War relevance (see: Force de frappe). It tested its first hydrogen bomb in 1968.
- The People's Republic of China tested its first nuclear weapon in 1964, much to the surprise of Western intelligence agencies. It had long sought assistance in becoming a nuclear power from an uneasy USSR, but assistance stopped after the Sino-Soviet split and the weapon was developed as a deterrent against both the USA and the USSR. It tested its first hydrogen bomb in 1967 at Lop Nur. The country is currently thought to have had a stockpile of around 130 warheads, potentially less.Norris, Robert S. and Hans M. Kristensen. "Chinese nuclear forces, 2006," Bulletin of the Atomic Scientists 62:3 (May/June 2006): 60-63, [link]; Lewis, Jeffery. "The ambiguous arsenal," Bulletin of the Atomic Scientists 61:3 (May/June 2005): 52-59. [link].
- India is not a member of the Nuclear Non-Proliferation Treaty, but tested a "peaceful nuclear device", as it was described by the Indian government, in 1974 ("Smiling Buddha"), the first test developed after the creation of the NPT, and created new questions about how civilian nuclear technology could be diverted secretly to weapons purposes (dual-use technology). It appears to have been primarily motivated as a deterrent against China. It tested weaponized nuclear warheads in 1998 ("Operation Shakti"), including a Hydrogen Bomb. In July 2005, it was officially recognized by the United States as a responsible nuclear state and agreed to full nuclear cooperation between the two nations.Carnegie Endowment for International Peace (carnegieendowment.org), [Proliferation Analysis: A Nuclear Triumph for India] This is seen as a tacit entry into the nuclear club of the above nations.
- Pakistan is not a member of the Nuclear Non-Proliferation Treaty. Pakistan covertly developed its nuclear weapons over many decades, beginning in the late 1970s. It is contended that Pakistan began its nuclear development programs in response to India's nuclear device. It is unknown when Pakistan began its nuclear development projects, but by the 1980s it was suspected of having successfully developed nuclear warheads. However, this was to remain speculative until 1998 when Pakistan conducted its first nuclear tests at the Chagai Hills, a few days after India conducted its own tests.
Suspected nuclear states
Countries believed to have at least one nuclear weapon, or programs with a realistic chance of producing a nuclear weapon in the near future:
- Israel - Israel is not a member of the Nuclear Non-Proliferation Treaty and refuses to officially confirm or deny having a nuclear arsenal, or to having developed nuclear weapons, or even to having a nuclear weapons program. Although Israel claims that the Negev Nuclear Research Center near Dimona is a "research reactor," no scientific reports based on work done there have ever been published. Extensive information about the program in Dimona was also disclosed by technician Mordechai Vanunu in 1986. Imagery analysts can identify weapon bunkers, mobile missile launchers, and launch sites in satellite photographs. It is believed to possess nuclear weapons by the International Atomic Energy Agency. Israel may have tested a nuclear weapon along with South Africa in 1979 (see Vela Incident). According to the Natural Resources Defense Council and the Federation of American Scientists, they may possess 300-400 weapons, a figure which would put them above the median in the declared list.Federation of American Scientists (fas.org) (August 17, 2000). [Israel's Nuclear Weapons]
- North Korea - On January 10, 2003 North Korea withdrew from the Nuclear Non-Proliferation Treaty. In February 2005 they claimed to possess functional nuclear weapons, though their lack of a test has led many experts to question whether or not they have a working weapon.
States suspected of having clandestine nuclear programs
The question of whether individual states without nuclear weapons are trying to develop them is often a controversial one. Accusations of clandestine nuclear programs are often vehemently denied, and may be politically motivated themselves, or simply erroneous. Below are countries who have been accused by a number of governments and intergovernmental agencies as currently attempting to develop nuclear weapons technology who are not suspected as yet having developed it.
- Iran - Iran signed the Nuclear Non-Proliferation Treaty and says its interest in nuclear technology, including enrichment, was for civilian purposes only (a right guaranteed under the treaty), but the United States of America's CIA and some other western countries suspect that this may be a cover for a nuclear weapons program, claiming that Iran has little need to develop nuclear power domestically and that it has consistently chosen nuclear options which were dual-use technology rather than those which could only be used for power generation.Nuclear Threat Intiative (nti.com) [Iran: Nuclear Chronology]; Federation of American Scientists (fas.org) (June 16, 2005). [Iran - Nuclear Weapons Recent Developments] The Iranian Foreign Minister Kamal Kharrazi stated on the intentions of his country's nuclear ambitions: "Iran will develop nuclear power abilities and these have to be recognized by the treaties."Fox News (June 12, 2004). [Iran Wants to Be Part of 'Nuclear Club'] As of February 4, 2006, the International Atomic Energy Agency referred Iran to the United Nations Security Council in response to Western concerns on their possible nuclear programs. On April 11, 2006, Iran's president announced that the country had successfully enriched uranium to reactor-grade levels for the first time. On April 22, 2006, Iran's envoy to the U.N. nuclear watchdog agency stated the Islamic republic had reached a "basic deal" with the Kremlin to form a joint uranium enrichment venture on Russian territory.CBS News (April 22, 2006). [Iran To Enrich Uranium In Russia]
- Saudi Arabia - In 2003 members of the government stated that due to the worsening relations with the USA, Saudi Arabia was being forced to consider the development of nuclear weapons. However, so far they have denied that they are making any attempt to produce them.The Guardian (September 18, 2003). [Saudis consider nuclear bomb] It has been rumored that Pakistan has transferred several nuclear weapons to Saudi Arabia, but this is unconfirmed.Akaki Dvali. Center for Nonproliferation Studies (nti.org) (March 2004). [Will Saudi Arabia Acquire Nuclear Weapons?]; Arnaud de Borchgrave. Washington Times (October 22, 2003) [Pakistan, Saudi Arabia in secret nuke pact] In March 2006 the German magazine Cicero reported that Saudi Arabia had since 2003 received assistance from Pakistan to acquire nuclear missiles and warheads. Satellite photos allegedly reveal an underground city and nuclear silos with Ghauri rockets south of the capital Riyadh."Saudia Arabia working on secret nuclear program with Pakistan help - report ", AFX News[link] Pakistan has denied aiding Saudi Arabia in any nuclear ambitions."[
