U.S. President
Ronald Reagan proposed this plan on 18 November 1981. He offered not to proceed with the deployment of
Pershing II and
cruise missiles – previously announced on 12 December 1979 and due to begin in 1983 – if the Soviet Union would remove its
SS-4,
SS-5 and
SS-20 missiles targeted on Western Europe. European and American
anti-nuclear activists denounced the Zero Option as designed to be rejected so that the U.S. could deploy the new missiles without condemnation by critics there and abroad. Reagan's proposal came to widespread public attention especially in Germany, where the translated term
Nullösung was chosen as
Word of the Year 1981 by the
Gesellschaft für deutsche Sprache. Following the coming to power of
Mikhail Gorbachev, however, nuclear arms control negotiations were resumed, and the Zero Option constituted the basis of the
Intermediate-Range Nuclear Forces Treaty, agreed in principle in September 1987 and signed on 8 December that year. ==Later similar disarmament concepts==
