It is a very far reaching control which would eliminate the rivalry between nations in this field, which would prevent the surreptitious arming of one nation against another, which would provide some cushion of time before atomic attack, and presumably therefore before any attack with weapons of mass destruction, and which would go a long way toward removing atomic energy at least as a source of conflict between the powers.

that contains an authoritative definition. Instead, international law has been used with respect to the specific categories of weapons within WMD, and not to WMD as a whole. While nuclear, chemical and biological weapons are regarded as the three major types of WMDs, some analysts have argued that radiological materials as well as missile technology and delivery systems such as aircraft and ballistic missiles could be labeled as WMDs as well.
However, there is an argument that nuclear and biological weapons do not belong in the same category as chemical and " dirty bomb" radiological weapons, which have limited destructive potential (and close to none, as far as property is concerned), whereas nuclear and biological weapons have the unique ability to kill large numbers of people with very small amounts of material, and thus could be said to belong in a class by themselves.
The NBC definition has also been used in official U.S. documents, by the

are considered weapons of mass destruction, while aircraft capable of carrying bombloads are not.
In 2004, the United Kingdom's Butler Review recognized the "considerable and long-standing academic debate about the proper interpretation of the phrase 'weapons of mass destruction. The committee set out to avoid the general term but when using it, employed the definition of United Nations Security Council Resolution 687, which defined the systems which Iraq was required to abandon:
* "Nuclear weapons or nuclear-weapons-usable material or any sub-systems or components or any research, development, support or manufacturing facilities relating to uclear weapons
* Chemical and biological weapons and all stocks of agents and all related subsystems and components and all research, development, support and manufacturing facilities.
* Ballistic missiles with a range greater than 150 kilometres and related major parts, and repair and production facilities."
Chemical weapons expert Gert G. Harigel considers only nuclear weapons true weapons of mass destruction, because "only nuclear weapons are completely indiscriminate by their explosive power, heat radiation and radioactivity, and only they should therefore be called a weapon of mass destruction". He prefers to call chemical and biological weapons "weapons of terror" when aimed against civilians and "weapons of intimidation" for soldiers.

''The Washington Post'' reported on 30 March 2006: "Jurors asked the judge in the death penalty trial of Zacarias Moussaoui today to define the term 'weapons of mass destruction' and were told it includes airplanes used as missiles". Moussaoui was indicted and tried for conspiracy to both destroy aircraft and use weapons of mass destruction, among others.
The surviving Boston Marathon bombing perpetrator, Dzhokhar Tsarnaev, was charged in June 2013 with the federal offense of "use of a weapon of mass destruction" after he and his brother Tamerlan Tsarnaev allegedly placed crude shrapnel bombs, made from pressure cookers packed with ball bearings and nails, near the finish line of the Boston Marathon. He was convicted in April 2015. The bombing resulted in three deaths and at least 264 injuries.
International law
The development and use of WMD is governed by several international conventions and treaties.
Use, possession, and access
Nuclear weapons
Nuclear weapons use the energy inside of an atom's nucleus to create massive explosions. This goal is achieved through nuclear fission and fusion.
Nuclear fission is when the nucleus of an atom is split into smaller nuclei. This process can be induced by shooting a neutron at the nucleus of an atom. When the neutron is absorbed by the atom, it becomes unstable, causing it to split and release energy. Modern nuclear weapons start this process by detonating chemical explosives around a pit of either uranium-235 or plutonium-239 metal. The force from this detonation is directed inwards, causing the pit of uranium or plutonium to compress to a dense point. Once the uranium/plutonium is dense enough, neutrons are then injected. This starts a fission chain reaction also known as an atomic explosion.
Nuclear fusion is essentially the opposite of fission. It is the fusing together of nuclei, not the splitting of it. When exposed to extreme pressure and temperature, some lightweight nuclei can fuse together and form heavier nuclei, releasing energy in the process. Fusion weapons (also known as “thermonuclear” or “hydrogen” weapons) use the fission process to initiate fusion. Fusion weapons use the energy released from a fission explosion to fuse hydrogen isotopes together. The energy released from these weapons creates a fireball, which reaches tens of million degrees. A temperature of this magnitude is similar to the temperature found at center of the sun; the sun runs on fusion as well.

At the start of 2024, nine states—the United States, Russia, the United Kingdom, France, China, India, Pakistan, the Democratic People’s Republic of Korea (North Korea) and Israel—together possessed approximately 12 121 nuclear weapons, of which 9585 were considered to be potentially operationally available. An estimated 3904 of these warheads were deployed with operational forces, including about 2100 that were kept in a state of high operational alert—about 100 more than the previous year.
South Africa and weapons of mass destruction, South Africa developed a small nuclear arsenal in the 1980s but disassembled them in the early 1990s, making it the only country to have fully given up an independently developed nuclear weapons arsenal. Belarus, Kazakhstan, and Ukraine inherited stockpiles of nuclear arms following the break-up of the Soviet Union, but relinquished them to the Russian Federation.
Countries where nuclear weapons are deployed through nuclear sharing agreements include Belgium, Germany and weapons of mass destruction, Germany, Italy, the Netherlands and weapons of mass destruction, Netherlands, and Turkey.
Biological weapons
The history of biological warfare goes back at least to the Golden Horde, Mongol siege of Caffa in 1346 and possibly much farther back to antiquity. It is believed that the Ancient Greece, Ancient Greeks contaminated their adversaries' wells by placing animal corpses in them. However, only by the turn of the 20th century did advances in microbiology allow for the large-scale weaponization of pathogens. During World War I, First World War, German military attempted to introduce anthrax into Allied livestock. In World War II, Second World War, Japan conducted aerial attacks on China using fleas carrying the bubonic plague. During the 20th century, at least nine states have operated offensive biological weapons programs, including Canada and weapons of mass destruction, Canada (1946–1956), France and weapons of mass destruction, France (1921–1972), Iraqi biological weapons program, Iraq (1985–1990s), Japan and weapons of mass destruction, Japan (1930s–1945), Rhodesia and weapons of mass destruction, Rhodesia, South Africa and weapons of mass destruction, South Africa (1981–1993), the Soviet biological weapons program, Soviet Union (1920s–1992), the United Kingdom and weapons of mass destruction, United Kingdom (1934–1956), and the United States biological weapons program, United States (1943–1969). The Japanese biological weapons program, which was run by the secret Imperial Japanese Army Unit 731 during the Sino-Japanese War (1937–1945), became infamous for conducting often fatal Human experimentation, human experiments on prisoners and producing biological weapons for combat use. The Soviet Union covertly operated the world's largest, longest, and most sophisticated biological weapons program, in violation of its obligations under international law.
International restrictions on biological warfare began with the 1925
Geneva Protocol
The Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or other Gases, and of Bacteriological Methods of Warfare, usually called the Geneva Protocol, is a treaty prohibiting the use of chemical and biological weapons in ...
, which prohibits the use but not the possession or development of biological and chemical weapons. Upon ratification of the Geneva Protocol, several countries made Reservation (law), reservations regarding its applicability and use in retaliation. Due to these reservations, it was in practice a "No first use, no-first-use" agreement only. The 1972 Biological Weapons Convention (BWC) supplements the Geneva Protocol by prohibiting the development, production, acquisition, transfer, stockpiling, and use of biological weapons. Having entered into force on 26 March 1975, the BWC was the first multilateral disarmament treaty to ban the production of an entire category of weapons of mass destruction. As of March 2021, List of parties to the Biological Weapons Convention, 183 states have become party to the treaty.
Chemical weapons
Chemical weapons have been used around the world by various civilizations since ancient times. The oldest reported case of a chemical substance being used as a weapon was in 256 AD during the siege of Dura-Europos. A mixture of tar and sulfur was used to produce sulfur oxides, which helped take control of the city. In the industrial era, chemical weapons were used extensively by both sides during Chemical weapons in World War I, World War I, and by the Axis powers during

(both in battle and in extermination camp Gas chamber#Germany, gas chambers) though Allied powers also stockpiled them.
International restrictions on chemical warfare began with the Hague Conventions of 1899 and 1907, and was expanded significantly by the 1925
Geneva Protocol
The Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or other Gases, and of Bacteriological Methods of Warfare, usually called the Geneva Protocol, is a treaty prohibiting the use of chemical and biological weapons in ...
. These treaties prohibited the use of poisons or chemical agents in international warfare, but did not place restrictions on development or weapon stockpiles. Since 1997, the Chemical Weapons Convention, Chemical Weapons Convention (CWC) has expanded restrictions to prohibit any use and development of chemical weapons except for very limited purposes (research, medical, pharmaceutical or protective). As of 2018, a handful of countries have known inventories, and many are in the process of being safely destroyed. Nonetheless, proliferation and use in war zones remains an active concern, most recently the use of chemical weapons in the Syrian Civil War.
Ethics and international legal status
Some commentators classify some or all the uses of nuclear, chemical, or biological weapons during wartime as a war crime (or crime against humanity if widespread) because they kill civilians (who are protected by the laws of war) indiscriminately or are specifically prohibited by international treaties (which have become more comprehensive over time). Proponents of use say that specific uses of such weapons have been necessary for defense or to avoid more deaths in a protracted war. The tactic of terror bombing from aircraft, and generally Aerial bombing of cities, targeting cities with area bombardment or saturation carpet bombing has also been criticized, defended, and prohibited by treaty in the same way; the destructive effect of conventional saturation bombing is similar to that of a nuclear weapon.
United States politics
Due to the potentially indiscriminate effects of WMD, the fear of a WMD attack has shaped political policies and campaigns, fostered social movements, and has been the central theme of many films. Support for different levels of WMD development and control varies nationally and internationally. Yet understanding of the nature of the threats is not high, in part because of imprecise usage of the term by politicians and the media.
Fear of WMD, or of threats diminished by the possession of WMD, has long been used to catalyze public support for various WMD policies. They include mobilization of pro- and anti-WMD campaigners alike, and generation of popular political support. The term WMD may be used as a powerful buzzword or to generate a culture of fear. It is also used ambiguously, particularly by not distinguishing among the different types of WMD.
A television commercial called ''Daisy (television commercial), Daisy'', promoting Democrat Lyndon Johnson's 1964 U.S. presidential election, 1964, presidential candidacy, invoked the fear of a nuclear war and was an element in Johnson's subsequent election.
Later, United States' President George W. Bush used the threat of potential WMD in Iraq as justification for the 2003 invasion of Iraq. Broad reference to Iraqi WMD in general was seen as an element of President Bush's arguments. The claim that Iraq possessed Weapons of Mass Destruction (WMD) was a major factor that led to the invasion of Iraq in 2003 by Multinational force in Iraq, Coalition forces.
Over 500 munitions containing mustard agent and sarin were discovered throughout Iraq since 2003; they were made in the 1980s and are no longer usable as originally intended due to corrosion.
The ''American Heritage Dictionary'' defines a weapon of mass destruction as: "a weapon that can cause widespread destruction or kill large numbers of people, especially a nuclear, chemical, or biological weapon." In other words, it does not have to be nuclear, biological or chemical (NBC). For example, Dzhokhar Tsarnaev, one of the perpetrators of the Boston Marathon bombing, was charged under United States law 18 U.S.C. 2332A for using a weapon of mass destruction and that was a pressure cooker bomb. In other words, it was a weapon that caused large-scale death and destruction, without being an NBC weapon.
Media coverage
In March 2004, the Center for International and Security Studies at Maryland (CISSM) released a report examining the media's coverage of WMD issues during three separate periods: Nuclear testing, nuclear weapons tests by India and Pakistan in May 1998; the U.S. announcement of evidence of a North Korea and weapons of mass destruction, North Korean nuclear weapons program in October 2002; and revelations about Iran's nuclear program in May 2003. The CISSM report argues that poor coverage resulted less from political Media bias, bias among the media than from tired journalistic conventions. The report's major findings were that:
In a separate study published in 2005, a group of researchers assessed the effects reports and retractions in the media had on people's memory regarding the Iraq and weapons of mass destruction, search for WMD in Iraq during the 2003 Iraq War. The study focused on populations in two Coalition of the willing, coalition countries (Australia and the United States) and one opposed to the war (Germany). Results showed that U.S. citizens generally did not correct initial misconceptions regarding WMD, even following disconfirmation; Australian and German citizens were more responsive to retractions. Dependence on the initial source of information led to a substantial minority of Americans exhibiting false memories, false memory that WMD were indeed discovered, while they were not. This led to three conclusions:
# The repetition of tentative news stories, even if they are subsequently disconfirmed, can assist in the creation of false memories in a substantial proportion of people.
# Once information is published, its subsequent correction does not alter people's beliefs unless they are suspicious about the motives underlying the events the news stories are about.
# When people ignore corrections, they do so irrespective of how certain they are that the corrections occurred.
A poll conducted between June and September 2003 asked people whether they thought evidence of WMD had been discovered in Iraq since the war ended. They were also asked which media sources they relied upon. Those who obtained their news primarily from Fox News were three times as likely to believe that evidence of WMD had been discovered in Iraq than those who relied on PBS and NPR for their news, and one third more likely than those who primarily watched CBS.
Based on a series of polls taken from June–September 2003.
In 2006, Fox News reported the claims of two Republican lawmakers that WMDs had been found in Iraq, based upon unclassified portions of a report by the National Ground Intelligence Center. Quoting from the report, Senator Rick Santorum said "Since 2003, coalition forces have recovered approximately 500 weapons munitions which contain degraded mustard or sarin nerve agent". According to David Kay, who appeared before the U.S. House Armed Services Committee to discuss these badly corroded munitions, they were leftovers, many years old, improperly stored or destroyed by the Iraqis. Charles Duelfer agreed, stating on NPR's ''Talk of the Nation'': "When I was running the ISG – the Iraq Survey Group – we had a couple of them that had been turned in to these IEDs, the improvised explosive devices. But they are local hazards. They are not a major, you know, weapon of mass destruction."
Later, wikileaks would show that WMDs of these kinds continued to be found as the Iraqi occupation continued.
Many news agencies, including Fox News, reported the conclusions of the CIA that, based upon the investigation of the Iraq Survey Group, WMDs are yet to be found in Iraq.
Public perceptions
Awareness and opinions of WMD have varied during the course of their history. Their threat is a source of unease, security, and pride to different people. The anti-WMD movement is embodied most in nuclear disarmament, and led to the formation of the British Campaign for Nuclear Disarmament in 1957.
In order to increase awareness of all kinds of WMD, in 2004 the nuclear physicist and Nobel Peace Prize winner Joseph Rotblat inspired the creation of The WMD Awareness Programme to provide trustworthy and up to date information on WMD worldwide.
In 1998, the University of New Mexico's Institute for Public Policy released their third report on U.S. perceptions – including the general public, politicians and scientists – of nuclear weapons since the breakup of the Soviet Union. Risks of nuclear conflict, proliferation, and terrorism were seen as substantial.
While maintenance of the U.S. nuclear arsenal was considered above average in importance, there was widespread support for a reduction in the stockpile, and very little support for developing and testing new nuclear weapons.
Also in 1998, nuclear weapons became an issue in India's election of March, in relation to political tensions with neighboring Pakistan. Prior to the election the Bharatiya Janata Party (BJP) announced it would "declare India a nuclear weapon state" after coming to power.
BJP won the elections, and on 14 May, three days after India tested nuclear weapons for the second time, a public opinion poll reported that a majority of Indians favored the country's nuclear build-up.
On 15 April 2004, the Program on International Policy Attitudes (PIPA) reported that U.S. citizens showed high levels of concern regarding WMD, and that preventing the nuclear proliferation, spread of nuclear weapons should be "a very important U.S. foreign policy goal", accomplished through multilateral arms control rather than the use of military threats.
A majority also believed the United States should be more forthcoming with its biological research and its Nuclear Non-Proliferation Treaty commitment of nuclear arms reduction.
A Russian opinion poll conducted on 5 August 2005 indicated half the population believed new nuclear powers have the right to possess nuclear weapons. 39% believed the Russian stockpile should be reduced, though not eliminated.
In popular culture

, as both political commentary and humorous outlet. The actual phrase "weapons of mass destruction" has been used similarly and as a way to characterise any powerful force or product since the Iraqi weapons crisis in the lead up to the Coalition invasion of Iraq in 2003. Science-fiction may introduce novel weapons of mass destruction with much greater yields or impact than anything in reality.
The term; “Weapon of Mass Destruction”, verbatim, is voiced in the American dubbed 1964 anime television show Gigantor. Season 1, episode 3 (Japan, 1963)
Common hazard symbols
Radioactive weaponry or hazard symbol
The international radioactivity symbol (also known as trefoil) first appeared in 1946, at the University of California, Berkeley Radiation Laboratory. At the time, it was rendered as magenta, and was set on a blue background.
It is drawn with a central circle of radius ''R'', the blades having an internal radius of 1.5''R'' and an external radius of 5''R'', and separated from each other by 60°. It is meant to represent a radiating atom.
The

found that the trefoil radiation symbol is unintuitive and can be variously interpreted by those uneducated in its meaning; therefore, its role as a hazard warning was compromised as it did not clearly indicate "danger" to many non-Westerners and children who encountered it. As a result of research, a new radiation hazard symbol (ISO 21482) was developed in 2007 to be placed near the most dangerous parts of radiation sources featuring a skull, someone running away, and using a red rather than yellow background.
The red background is intended to convey urgent danger, and the sign is intended to be used on equipment where very strong ionizing radiation can be encountered if the device is dismantled or otherwise tampered with. The intended use of the sign is not in a place where the normal user will see it, but in a place where it will be seen by someone who has started to dismantle a radiation-emitting device or equipment. The aim of the sign is to warn people such as scrap metal workers to stop work and leave the area.
