biological warfare (redirected from Biological war)

biological warfare, employment in war of microorganisms to injure or destroy people, animals, or crops; also called germ or bacteriological warfare. Limited attempts have been made in the past to spread disease among the enemy; e.g., military leaders in the French and Indian Wars tried to spread smallpox among the Native Americans. Biological warfare has scarcely been used in modern times and was prohibited by the 1925 Geneva Convention. However, many nations in the 20th cent. have conducted research to develop suitable military microorganisms, including strains of smallpox, anthrax, plague, and some nonlethal agents. Such microorganisms can be delivered by animals (especially rodents or insects) or by aerosol packages, built into artillery shells or the warheads of ground-to-ground or air-to-ground missiles and released into the atmosphere to infect by inhalation.

In 1972 the United States and the Soviet Union adopted an agreement, endorsed by the UN General Assembly and now ratified by more than 140 nations, to destroy existing stockpiles of biological weapons and refrain from developing or stockpiling new biological weapons. The treaty does allow research for defensive purposes, such as to develop antidotes to biological weapons. After the fall of the Soviet Union, however, it was disclosed that the Soviets had secretly increased research and production of a wide variety of deadly biological agents. Although Russian president Boris Yeltsin publicly ordered (1992) the abandonment of germ warfare, some expressed suspicion about the continued production of biological weapons in post–cold war Russia.

With the rise of extremist groups and the disintegration of the established international political order in the late 20th cent., biological weapons again began to be perceived as a serious threat. In the 1990s, after the Persian Gulf War, five hidden germ-warfare laboratories and stockpiles of anthrax, botulism, and gas gangrene bacteria were discovered in Iraq. In addition to Iraq and Russia, North Korea, Iran, Egypt, Israel, China, and other nations are suspected of various violations of the 1972 agreement.

In 2001, shortly after the terrorist attacks on the World Trade Center and Pentagon, anthrax was sent through the mail in bioterrorist attacks against several locations in the United States. There was, however, no clear connection between the two terror attacks. In an attempt to develop a warning system for a bioterror attack, the Environmental Protection Agency's air quality monitoring system was adapted (2003) to permit detection of an outdoor release of smallpox and other pathogens. Such a system, however, would not have detected the narrowly focused indoor anthrax attacks of 2001.

biological warfare

 or germ warfare

Military use of disease-producing or poisonous agents, and the means for defending against such agents. Biological warfare agents include many bacteria, such as those which cause anthrax, brucellosis, and typhus; viruses that cause diseases such as equine encephalitis; fungi such as rice blast, cereal rust, wheat smut, and potato blight; and toxins such as botulinum and ricin that are extracted from living organisms. Biological warfare dates from ancient times when warring groups would try to poison enemy soldiers with rotting or diseased corpses, infect cattle and horses, or spread contagion through civilian populations. Following the horrors of World War I, a 1925 Geneva Protocol prohibited the use of biological agents in warfare; however, this did not prevent Japan from using them in China during World War II. During the Cold War the Soviet Union as well as the U.S. and its allies built huge stockpiles of biological agents. Both sides signed the 1972 Biological Weapons Convention, which prohibits the production, stockpiling, or development of biological weapons and requires the destruction of existing stockpiles, but the Soviets conducted a clandestine program until the 1990s. Biological weapons programs can be concealed easily, and the 1972 convention contains no provisions for inspection and reporting. As a result, many states have been suspected of developing biological warfare agents, and some modern armed forces have prepared defensive measures. These include battlefield sensors, protective garments and masks, sterilizing agents, and vaccines.
