The two nations had conflicting aims in Europe and elsewhere, and the Cold War was basically the result of these conflicts. The US and USSR engaged in a global competition in the form of an arms race as well as attempts to influence events in developing countries. A dangerous time that, for all our current problems, I wouldn't want to return to.
Yes, there is big difference between the US and the USSR. At the time that the USSR existed, we were not friendly with it. The United States was in a space race with the Soviet Union, and was afraid they were going to send a missile at us.
The USSR disintegrated shortly after the symbolic fall of the Berlin Wall and the "Iron Curtain" in 1989 when the governments of East and West Germany decided to reunify. It marked the first stages of the end of the Socialist states that had existed since the end of World War II.
The USSR no longer exists. It was the Union of Soviet Socialist Republics and it broke up about 20 years ago. Its relationship with the US was that they were competitors in the Cold War that lasted from 1945 to 1991. They were competitors because the Soviets were communist and the US was a democracy/capitalism.
The acronym, USSR, means Union of Soviet Socialist Republics. One might also call it the Russian Empire because besides Russia, it included at least 14 other countries.
Armenia, Azerbaijan, Belarus, Estonia, Georgia, Kazakhstan, Kygyzstan, Latvia, Lithuania, Moldova, Tajikistan, Turkmenistan, Ukraine, and Uzbekikstan.
