According to many historians, both the US and the USSR were responsible for the Cold War, which lasted from 1945 to 1991. As a result, there was a division of Berlin and Germany, the Korean War, the Space Race, etc. Cold War sparked at the Yalta Conference when it was discussed how Germany would be divided. Nevertheless, it seems that the SSSR was more responsible for imposing communism in the countries of Eastern Europe, creating the Iron Curtain between the east and the west, "From Stettin in the Baltic to Trieste in the Adriatic, Iron Curtain spread across the continent," as Churchill stated. America, on the other hand, could not calmly observe the expansion of communism in Europe, because capitalism was not imposed in western countires, it was their choice, while the eastern countries could not choose, Stalin imposed communism in order to expand ideas of the Communist Revolution.
