The term nuclear option is used figuratively, especially in politics, to refer to a response that threatens “mutual assured destruction.” It is, as the Oxford English Dictionary defines it, “the most drastic of the possible responses to a situation.” But of course, it does have a more literal original sense.
It first appears in the early 1960s referring to the choice of a country to develop nuclear weapons. It appears in an article in the March 1962 issue of the American Political Science Review in reference to Britain’s decision to acquire a nuclear arsenal ten years earlier:
Nuclear forces were also thought to increase positive British influence over the United States by undertaking a share in the task of deterrence and demonstrating technological skill. Moreover the strategic nuclear option was a policy for which both the weapons and a doctrine existed.
That same year, it was used to refer to India’s potential for nuclear weapons in the title of a book review, “The Nuclear Option,” in the New Left Review. The review was of Leonard Beaton and John Maddox’s The Spread of Nuclear Weapons. The phrase does not appear in the review itself, only the title, but the following explains what the title refers to
Thus it emerges that India has an extensive nuclear programme designed to give it an option on nuclear weapons in about 1963. Very little is known about this in India, and Mr. Nehru, who is Minister of Atomic Energy as well as Prime Minister, seldom speaks about it: but from the analysis the book provides, it seems probable that India will go ahead and make nuclear weapons if the Chinese “menace” is considered to warrant it.
Beaton and Maddox’s book does not use the phrase either but makes extensive use of option in the context of the decision to acquire nuclear weapons. India demonstrated it had the capability to build a nuclear arsenal in 1974 with its detonation of a “peaceful” nuclear explosion, and it formally took the nuclear option in 1989, establishing an arsenal of the weapons probably by 1994 and openly testing one in 1998.
Literal use of nuclear option would also come to be used to refer the decision to use nuclear weapons in a war and also, less menacingly, in respect to the choice to use nuclear power for the generation of electricity.
The figurative sense of nuclear option was in place by the early 1990s. The earliest use I’m aware of is in 1993 in the context of UK Prime Minister John Major threatening a general election if a rebellious group of backbenchers in his party did not back him on the decision not to join the social aspects of the European Union. As recorded in The Independent on 23 July 1993:
Today John Major binds his own future as Prime Minister to the policy that lies at the heart of his Government’s meaning. He has detonated what one of his close friends called “the nuclear option”: back the social chapter opt-out or I’ll blow the party apart at a general election. Given the question, it seems certain he will win.
This incident and the phrase appeared in the American press in the same context. From the Washington Post, dateline also of 23 July 1993, an article that was syndicated widely in other papers:
To win the support of rebels within his own Conservative Party, Major had to threaten them with what became known as the “nuclear option”—he would resign as prime minister, dissolve Parliament and call a general election if they voted against him Friday. With the Conservatives lagging far behind in the polls, for the rebels to defy Major would have been, in the words of one Tory, “like turkeys voting for Christmas.”
Nuclear option would come to be used in American politics in the twenty-first century, most notably in reference to threats to end the filibuster in the US Senate.
