The Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT, is an international treaty whose objective is to prevent the spread of nuclear weapons and weapons technology, to promote cooperation in the peaceful uses of nuclear energy, and to further the goal of achieving nuclear disarmament and general and complete disarmament. Between 1965 and 1968, the treaty was negotiated by the Eighteen Nation Committee on Disarmament, a United Nations-sponsored organization based in Geneva, Switzerland.
Nuclear proliferation is the spread of nuclear weapons, fissionable material, and weapons-applicable nuclear technology and information to nations not recognized as "Nuclear Weapon States" by the Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT. Proliferation has been opposed by many nations with and without nuclear weapons, as governments fear that more countries with nuclear weapons will increase the possibility of nuclear warfare, de-stabilize international or regional relations, or infringe upon the national sovereignty of nation states.
A weapon of mass destruction (WMD) is a biological, chemical, radiological, nuclear, or any other weapon that can kill or significantly harm many people or cause great damage to artificial structures, natural structures, or the biosphere. The scope and usage of the term has evolved and been disputed, often signifying more politically than technically. Originally coined in reference to aerial bombing with chemical explosives during World War II, it has later come to refer to large-scale weaponry of warfare-related technologies, such as biological, chemical, radiological, or nuclear warfare.
Iraq actively researched and later employed weapons of mass destruction (WMD) from 1962 to 1991, when it destroyed its chemical weapons stockpile and halted its biological and nuclear weapon programs as required by the United Nations Security Council. The fifth president of Iraq, Saddam Hussein, was internationally condemned for his use of chemical weapons against Iranian and Kurdish civilians during the Iran–Iraq War in the 1980s. Saddam pursued an extensive biological weapons program and a nuclear weapons program, though no nuclear bomb was built. After the Gulf War, the United Nations located and destroyed large quantities of Iraqi chemical weapons and related equipment and materials; Iraq ceased its chemical, biological and nuclear programs.
The United States is known to have possessed three types of weapons of mass destruction: nuclear weapons, chemical weapons, and biological weapons. The U.S. is the only country to have used nuclear weapons on another country, when it detonated two atomic bombs over two Japanese cities of Hiroshima and Nagasaki during World War II. It had secretly developed the earliest form of the atomic weapon during the 1940s under the title "Manhattan Project". The United States pioneered the development of both the nuclear fission and hydrogen bombs. It was the world's first and only nuclear power for four years, from 1945 until 1949, when the Soviet Union produced its own nuclear weapon. The United States has the second-largest number of nuclear weapons in the world, after the Russian Federation.
The United Kingdom possesses, or has possessed, a variety of weapons of mass destruction, including nuclear, biological, and chemical weapons. The United Kingdom is one of the five official nuclear weapon states under the Treaty on the Non-Proliferation of Nuclear Weapons. The UK renounced the use of chemical and biological weapons in 1956 and subsequently destroyed its general stocks.
Israel is believed to possess weapons of mass destruction, and to be one of four nuclear-armed countries not recognized as a Nuclear Weapons State by the Non-Proliferation Treaty (NPT). The US Congress Office of Technology Assessment has recorded Israel as a country generally reported as having undeclared chemical warfare capabilities, and an offensive biological warfare program. Officially, Israel neither confirms nor denies possessing nuclear weapons.
Taiwan pursued a number of weapons of mass destruction programs from 1949 to the late 1980s. The final secret nuclear weapons program was shut down in the late 1980s under US pressure after completing all stages of weapons development besides final assembly and testing; they lacked an effective delivery mechanism and would have needed to further miniaturize any weapon before it could be effectively used in combat. Currently, there is no evidence of Taiwan possessing any chemical, biological, or nuclear weapons. However, nuclear weapons from the United States were deployed to Taiwan during a period of heightened regional tensions with China beginning with the First Taiwan Strait Crisis and ending in the 1970s.
Many nations continue to research and/or stockpile chemical weapon agents despite numerous efforts to reduce or eliminate them. Most states have joined the Chemical Weapons Convention (CWC), which required the destruction of all chemical weapons by 2012. Twelve nations have declared chemical weapons production facilities and six nations have declared stockpiles of chemical weapons. All of the declared production facilities have been destroyed or converted to civilian use after the treaty went into force.
Iran is not known to currently possess weapons of mass destruction (WMD) and has signed treaties repudiating the possession of WMDs including the Biological Weapons Convention, the Chemical Weapons Convention, and the Non-Proliferation Treaty (NPT). Iran has first-hand knowledge of WMD effects—over 100,000 Iranian troops and civilians were victims of chemical weapons during the 1980s Iran–Iraq War.
Nuclear sharing is a concept in NATO's policy of nuclear deterrence, which allows member countries without nuclear weapons of their own to participate in the planning for the use of nuclear weapons by NATO. In particular, it provides for involvement of the armed forces of those countries in delivering nuclear weapons in the event of their use.
Although Germany has the technical capability to produce weapons of mass destruction (WMD), since World War II it has refrained from producing those weapons. However, Germany participates in the NATO nuclear weapons sharing arrangements and trains for delivering United States nuclear weapons. Officially, 20 US-nuclear weapons are stationed in Büchel, Germany. It could be more or fewer, but the exact number of the weapons is a state secret.
Libya pursued programs to develop or acquire weapons of mass destruction from when Muammar Gaddafi seized control of Libya in 1969 until he announced on 19 December 2003 that Libya would voluntarily eliminate all materials, equipment and programs that could lead to internationally proscribed weapons. This included weapons of mass destruction and long-range ballistic missiles.
Syria and weapons of mass destruction deals with the research, manufacture, stockpiling and alleged use by Syria of weapons of mass destruction, which include chemical and nuclear weapons.
Volkel Air Base is a military airbase used by the Royal Netherlands Air Force (RNLAF) - Dutch: Koninklijke Luchtmacht (KLu), located near the village of Volkel, Netherlands. It is home to one F-16 Fighting Falcon squadron, No 312 and a F-35 squadron No 313 and a maintenance, logistical, a base Squadron for the RNLAF.
In 2009, it was reported that Myanmar was suspected to have initiated a nuclear weapons program. If such a program does exist, Burma's technical and financial limitations may make it difficult for the program to succeed. The United States expressed concern in 2011 about potential violations of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), though by 2012 these concerns had been "partially allayed".
In 2003, Libyan leader Muammar Gaddafi agreed to eliminate his country's weapons of mass destruction program, including a decades-old nuclear weapons program. Mohamed ElBaradei, head of the International Atomic Energy Agency, said Libya's nuclear program was "in the very initial stages of development" at the time.
The Treaty on the Prohibition of Nuclear Weapons (TPNW), or the Nuclear Weapon Ban Treaty, is the first legally binding international agreement to comprehensively prohibit nuclear weapons with the ultimate goal being their total elimination. It was adopted on 7 July 2017, opened for signature on 20 September 2017, and entered into force on 22 January 2021.
Saudi Arabia has not officially maintained and possessed weapons of mass destruction (WMD). In 1972 Saudi Arabia signed and approved the convention on the prohibition of the development, production and stockpiling of biological (bacteriological) and toxin weapons. Nevertheless, Saudi Arabia has made steps towards a nuclear program and according to some observations, they can be used to develop nuclear weapons. According to some reports, Riyadh has an alleged deal with Pakistan regarding nuclear weapons projects.
