The main reason for the collapse of the Soviet Union in the 1980s was that the Soviet economy could not match US military spending while also meeting the citizens' demands for consumer goods. Additionally, policies introduced by Mikhail Gorbachev, such as Perestroika and Glasnost, resulted in the Soviet Union losing its main source of income. The United States also played a role in convincing Soviet leaders to abandon communist economic policies, which further weakened the Soviet economy.
