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:

Who can think at this present time without a sickening of the heart of the appalling slaughter, the suffering, the manifold misery brought by war to Spain and to China ? Who can think without horror of what another widespread war would mean, waged as it would be with all the new weapons of mass destruction?

At the time, nuclear weapons had not been developed. Japan conducted research on biological weapons, and chemical weapons had seen wide battlefield use in World War I. Their use was outlawed by the Geneva Protocol of 1925. Italy used mustard agent against civilians and soldiers in Ethiopia in 1935–36.

Following the atomic bombings of Hiroshima and Nagasaki that ended World War II and during the Cold War, the term came to refer more to non- conventional weapons. The application of the term to specifically nuclear and radiological weapons is traced by William Safire to the Russian phrase "Оружие массового поражения" – oruzhiye massovogo porazheniya (weapon of mass destruction).

William Safire credits James Goodby (of the Brookings Institution) with tracing what he considers the earliest known English-language use soon after the nuclear bombing of Hiroshima and Nagasaki (although it is not quite verbatim): a communique from a 15 November 1945, meeting of Harry Truman, Clement Attlee and Mackenzie King (probably drafted by Vannevar Bush, as Bush claimed in 1970) referred to "weapons adaptable to mass destruction."

Safire says Bernard Baruch used that exact phrase in 1946 (in a speech at the United Nations probably written by Herbert Bayard Swope). The phrase found its way into the very first resolution the United Nations General assembly adopted in January 1946 in London, which used the wording "the elimination from national armaments of atomic weapons and of all other weapons adaptable to mass destruction." The resolution also created the Atomic Energy Commission (predecessor of the International Atomic Energy Agency (IAEA)).

An exact use of this term was given in a lecture titled " Atomic Energy as a Contemporary Problem" by J. Robert Oppenheimer. He delivered the lecture to the Foreign Service and the State Department, on 17 September 1947.

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.

The term was also used in the introduction to the hugely influential U.S. government document known as NSC 68 written in 1950.

During a speech at Rice University on 12 September 1962, President John F. Kennedy spoke of not filling space "with weapons of mass destruction, but with instruments of knowledge and understanding." The following month, during a televised presentation about the Cuban Missile Crisis on 22 October 1962, Kennedy made reference to "offensive weapons of sudden mass destruction."

An early use of the exact phrase in an international treaty is in the Outer Space Treaty of 1967, but the treaty provides no definition of the phrase, and the treaty also categorically prohibits the stationing of "weapons" and the testing of "any type of weapon" in outer space, in addition to its specific prohibition against placing in orbit, or installing on celestial bodies, "any objects carrying nuclear weapons or any other kinds of weapons of mass destruction."
