Portal:Weapons of mass destruction/Intro

From Wikipedia, the free encyclopedia

Weapon of mass destruction (WMD) is a term used to describe a munition with the capacity to indiscriminately kill large numbers of humans. The phrase broadly encompasses several areas of weapon synthesis, including nuclear, biological, chemical (NBC) and, increasingly, radiological weapons.

The term first arose in 1937 in reference to the mass destruction of Guernica, Spain, by aerial bombardment.[1] Following the bombing of Hiroshima and Nagasaki, and progressing through the Cold War, the term came to refer more to non-conventional weapons. The phrase entered popular usage in relation to the U.S.-led 2003 invasion of Iraq. Terms used in a military context include atomic, biological, and chemical warfare (ABC warfare), nuclear, biological, and chemical (NBC) after the invention of the hydrogen bomb, and chemical, biological, radiological, and nuclear (CBRN), recognizing the threat of non-explosive radiological weapons.

Due to the indiscriminate impacts caused by WMD, the fear of WMD 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.
