The Late 1980s: A Turning Point in US-Soviet Relations
In the late 1980s, a major development in US-Soviet relations was the signing of the Intermediate-Range Nuclear Forces Treaty (INF Treaty) by President Ronald Reagan and Soviet leader Mikhail Gorbachev in 1987. This treaty marked a significant step towards reducing nuclear tensions between the two superpowers.
Additionally, the Reykjavik Summit in 1986 between Reagan and Gorbachev laid the groundwork for future arms control agreements and symbolized a shift towards dialogue and cooperation.
Furthermore, Gorbachev's policies of glasnost and perestroika, aimed at reforming the Soviet Union's political and economic systems, contributed to a thaw in US-Soviet relations and eventually led to the end of the Cold War.
