The Reykjavík Summit was a summit meeting between U.S. President Ronald Reagan and General Secretary of the Communist Party of the Soviet Union Mikhail Gorbachev, held in Hofdi in Reykjavík, on 11–12 October 1986. The talks collapsed at the last minute, but the progress that had been achieved eventually resulted in the 1987 Intermediate-Range Nuclear Forces Treaty between the United States and the Soviet Union.
In 1986, Gorbachev had proposed banning all ballistic missiles, but Reagan wanted to continue research on the Strategic Defense Initiative (SDI), which involved the militarization of outer space. Yet Soviet suspicion of SDI continued, and U.S.-Soviet relations — already strained by the failure of the Geneva Summit the previous year — were further strained by the Daniloff-Zakharov espionage affair.
At Reykjavík, Reagan sought to include discussion of human rights, emigration of Soviet Jews and dissidents, and the Soviet invasion of Afghanistan. Gorbachev sought to limit the talks solely to arms control. The Soviets acceded to the "double-zero" proposal for eliminating INF weapons from Europe, as initially proposed by President Reagan in November 1981 (INF denoting "Intermediate-Range Nuclear Forces" as distinct from ICBMs, or intercontinental ballistic missiles). The Soviets also proposed to eliminate 50% of all strategic arms, including ICBMs, and agreed not to include British or French weapons in the count. All this was proposed in exchange for an American pledge not to implement strategic defences for the next ten years, in accordance with SALT I.
