Gorbachev's policy decisions refer to the significant reforms introduced by Mikhail Gorbachev during his leadership of the Soviet Union in the 1980s, primarily known as glasnost (openness) and perestroika (restructuring). These policies aimed to modernize the Soviet economy and promote greater transparency and freedom of expression, ultimately contributing to the end of the Cold War by reducing tensions between the East and West and fostering democratic movements within Eastern Europe.
