WMDs
A weapon of mass destruction (WMD) is a chemical, biological, radiological, nuclear, or any other weapon that can kill and bring significant harm to numerous individuals or cause great damage to artificial structures (e.g., buildings), natural structures (e.g., mountains), 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 chemical, biological, radiological, or nuclear warfare. Early uses of this term The first use of the term "weapon of mass destruction" on record is by Cosmo Gordon Lang, Archbishop of Canterbury, in 1937 in reference to the aerial bombing of Guernica, Spain: At the time, nuclear weapons had not been developed. Japan conducted research on biological weapons (see Unit 731), and chemical weapo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiological Weapons
Radiological warfare is any form of warfare involving deliberate radiation poisoning or contamination of an area with radiological sources. Radiological weapons are normally classified as weapons of mass destruction (WMDs), although radiological weapons can also be specific in whom they target, such as the radiation poisoning of Alexander Litvinenko by the Russian FSB, using radioactive polonium-210. Numerous countries have expressed an interest in radiological weapons programs, several have actively pursued them, and three have performed radiological weapons tests. Salted nuclear weapons A salted bomb is a nuclear weapon that is equipped with a large quantity of radiologically inert salting material. The radiological warfare agents are produced through neutron capture by the salting materials of the neutron radiation emitted by the nuclear weapon. This avoids the problems of having to stockpile the highly radioactive material, as it is produced when the bomb explodes. The r ...

Chemical Warfare
Chemical warfare (CW) involves using the toxic properties of chemical substances as weapons. This type of warfare is distinct from nuclear warfare, biological warfare and radiological warfare, which together make up CBRN, the military acronym for chemical, biological, radiological, and nuclear (warfare or weapons), all of which are considered "weapons of mass destruction" (WMDs), a term that contrasts with conventional weapons. The use of chemical weapons is prohibited under customary international humanitarian law. Definition Chemical warfare is different from the use of conventional weapons or nuclear weapons because the destructive effects of chemical weapons are not primarily due to any explosive force. The offensive use of living organisms (such as anthrax) is considered biological warfare rather than chemical warfare; however, the use of nonliving toxic products produced by living organisms (e.g. toxins such as botulinum toxin, ricin, and saxitoxin) ''is'' consider ...

Unit 731
, short for Manshu Detachment 731 and also known as the Kamo Detachment and Ishii Unit, was a covert biological and chemical warfare research and development unit of the Imperial Japanese Army that engaged in lethal human experimentation and biological weapons manufacturing during the Second Sino-Japanese War (1937–1945) and World War II. The unit’s estimated kills were between 200,000 and 300,000. It was based in the Pingfang district of Harbin, the largest city in the Japanese puppet state of Manchukuo (now Northeast China) and had active branch offices throughout China and Southeast Asia. Unit 731 was responsible for some of the most notorious war crimes committed by the Japanese armed forces. It routinely conducted tests on people who were dehumanized and internally referred to as "logs". Experiments included disease injections, controlled dehydration, hypobaric chamber experiments, biological weapons testing, vivisection, amputation, and standard weapons tes ...

Second Sino-Japanese War
The Second Sino-Japanese War (1937–1945) or War of Resistance (Chinese term) was a military conflict that was primarily waged between the Republic of China and the Empire of Japan. The war made up the Chinese theater of the wider Pacific Theater of the Second World War. The beginning of the war is conventionally dated to the Marco Polo Bridge Incident on 7 July 1937, when a dispute between Japanese and Chinese troops in Peking escalated into a full-scale invasion. Some Chinese historians believe that the Japanese invasion of Manchuria on 18 September 1931 marks the start of the war. This full-scale war between the Chinese and the Empire of Japan is often regarded as the beginning of World War II in Asia. China fought Japan with aid from Nazi Germany, the Soviet Union, United Kingdom and the United States. After the Japanese attacks on Malaya and Pearl Harbor in 1941, the war merged with other conflicts which are generally categorized under those conflicts of World War II a ...

Nuclear Weapons
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been deployed ...

Biological Weapons
A biological agent (also called bio-agent, biological threat agent, biological warfare agent, biological weapon, or bioweapon) is a bacterium, virus, protozoan, parasite, fungus, or toxin that can be used purposefully as a weapon in bioterrorism or biological warfare (BW). In addition to these living or replicating pathogens, toxins and biotoxins are also included among the bio-agents. More than 1,200 different kinds of potentially weaponizable bio-agents have been described and studied to date. Biological agents have the ability to adversely affect human health in a variety of ways, ranging from relatively mild allergic reactions to serious medical conditions, including serious injury, as well as serious or permanent disability or even death. Many of these organisms are ubiquitous in the natural environment where they are found in water, soil, plants, or animals. Bio-agents may be amenable to "weaponization" to render them easier to deploy or disseminate. Genetic modification m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Weapons
A chemical weapon (CW) is a specialized Ammunition, munition that uses chemicals chemical engineering, formulated to inflict death or harm on humans. According to the Organisation for the Prohibition of Chemical Weapons (OPCW), this can be any chemical compound intended as a weapon "or its Precursor (chemistry), precursor that can cause death, injury, temporary incapacitation or sensory irritation through its chemical action. Munitions or other delivery devices designed to deliver chemical weapons, whether filled or unfilled, are also considered weapons themselves." Chemical weapons are classified as weapons of mass destruction (WMD), though they are distinct from nuclear weapons, biological warfare, biological weapons, and radiological weapons. All may be used in warfare and are known by the military acronym NBC (for nuclear, biological, and chemical warfare). Weapons of mass destruction are distinct from conventional weapons, which are primarily effective due to their explos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombing Of Guernica
On 26 April 1937, the Basque town of Guernica (''Gernika'' in Basque) was aerial bombed during the Spanish Civil War. It was carried out at the behest of Francisco Franco's rebel Nationalist faction by its allies, the Nazi German Luftwaffe's Condor Legion and the Fascist Italian Aviazione Legionaria, under the code name "Operation Rügen". The town was being used as a communications centre by Republican forces just behind the front line, and the raid was intended to destroy bridges and roads. The operation opened the way to Franco's capture of Bilbao and his victory in northern Spain. The attack gained controversy because it involved the bombing of civilians by a military air force. Seen as a war crime by some historians, and argued as a legitimate attack by others, it was one of the first aerial bombings to capture global attention. The number of victims is still disputed; the Basque government reported 1,654 people killed at the time, while local historians identified 126 ...

Sulfur Mustard
Mustard gas or sulfur mustard is a chemical compound belonging to a family of cytotoxic and blister agents known as mustard agents. The name ''mustard gas'' is technically incorrect: the substance, when dispersed, is often not actually a gas, but is instead in the form of a fine mist of liquid droplets.https://www.acs.org/content/dam/acsorg/education/resources/highschool/chemmatters/gc-mustard-gas-personal-safety-and-natl-security.pdf Mustard gases form blisters on exposed skin and in the lungs, often resulting in prolonged illness ending in death. The active ingredient in typical mustard gas is the organosulfur compound bis(2-chloroethyl) sulfide. In the wider sense, compounds with the structural element are known as ''sulfur mustards'' and ''nitrogen mustards'', respectively. Such compounds are potent alkylating agents, which can interfere with several biological processes. History as chemical weapons As a chemical weapon, mustard gas was first used in World War I, and has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
