In January 1986, Gorbachev publicly proposed a three-stage programme for abolishing the world's nuclear weapons by the end of the 20th century. An agreement was then reached to meet with Reagan in Reykjavík, Iceland in October 1986. Gorbachev wanted to secure guarantees that SDI would not be implemented, and in return was willing to offer concessions, including a 50% reduction in Soviet long range nuclear missiles. Both leaders agreed with the shared goal of abolishing nuclear weapons, but Reagan refused to terminate the SDI program and no deal was reached. After the summit, many of Reagan's allies criticized him for going along with the idea of abolishing nuclear weapons. Gorbachev meanwhile told the Politburo that Reagan was "extraordinarily primitive, troglodyte, and intellectually feeble".
