Answer:
-affected nations throughout the world
-reduced the number of Communist nations in the world
-changed boundaries in Europe
Explanation:
-affected nations throughout the world
:
The collapse of the USSR put an end to the Cold War, which affected many nations throughout the world. The Dissolution of the Soviet Union or the Dissolution of the USSR was the disintegration of federal political structures and the central government of the Union of Soviet Socialist Republics (USSR), which culminated in the independence of the fifteen republics of the Soviet Union between March 11, 1990, and December 25, 1991.
-reduced the number of Communist nations in the world:
Most of the satellite Communist countries that were orbiting the USSR abandoned Communism and slowly adopted a free-market economy. Only a few countries remained Communist after the end of the Cold War, such as North Korea and Cuba.
-changed boundaries in Europe:
The disintegration of the Soviet Union is related to the context that emerged after the end of the Cold War and the dissolution of other countries in the Eastern bloc such as the dissolution of Yugoslavia and the dissolution of Czechoslovakia. Unlike Czechoslovakia, it was not a peaceful dissolution and proof of this is the existence of latent conflicts such as those in Abkhazia, South Ossetia, Nagorno Karabakh, Transnistria, Chechnya, or Crimea. But unlike Yugoslavia, it also did not degenerate into an open war such as the Yugoslav Wars.
