Definition of Weapons of Mass Destruction (WMD)

The term of “Weapons fo Mass Destruction” was first used in 1937 and only refered to the aerial bombing with chemical explosive because at that time, nuclear weapon had not been developed. The definition, however, changed after The US detonated two atomic bombs in Japan’s Horishima and Nagasaki cities during world war II. The term “weapons of mass destruction” (WMD) was then expressly defined by the United Nations in 1948 as “atomic explosive weapons, radioactive material weapons, lethal chemical and biological weapons, and any weapons developed in the future which have characteristics comparable in destructive effect to those of the atomic bomb or other weapons mentioned above”
