Ronald Reagan and Mikhail Gorbachev first met in Geneva in 1985, in a summit specifically designed to allow them to discuss diplomatic relations and the -nuclear- arms race. At the time, the Soviet Union had started to crumble, but it was still very much the Soviet Union. They met again in 1986 in Reykjavik, in a summit set up to continue these talks. There, they came close to an agreement to dismantle both countries’ nuclear arsenals.
They met once again in Washington in 1987. That was the year Reagan made his famous “Mr. Gorbachev, tear down this wall” speech about the Berlin wall. Then they held a next summit in 1988 in Moscow, where they finalized the Intermediate-Range Nuclear Forces Treaty (INF) after the US Senate’s ratification of the treaty in May 1988.
