Only Russia, as the USSR was just another name for Soviet Russia :)
Additional answer
Actually, USSR is NOT just another name for Russia. USSR stands for Union of Soviet Socialist Republics and is an agglomeration of a whole lot of countries, including Russia. It was formed in 1922 and disbanded after the fall of communism in 1991
During World War II, the USSR fought primarily against Nazi Germany and its allies, including Italy and Japan. Initially, the USSR had a non-aggression pact with Germany, but this changed when Germany invaded the Soviet Union in June 1941. The USSR was also part of the Allies, collaborating with countries like the United States and the United Kingdom to defeat the Axis powers.
The Axis fought the Allies. The Allies were many countries, some of which were only involved for part of the war. Chief amongst the Allies were Great Britain, her Empire and Commonwealth, the USSR, the USA and France. But the Axis countries also fought countries such as Norway, Denmark, the Netherlands, Belgium, Poland, Thailand (it was called Siam then), China, Greece etc. So World War Two was truly a world war.

The European countries that were part of the Allies during World War II included the United Kingdom, France, and Poland, among others. Additionally, countries like Belgium, Norway, the Netherlands, and Greece also aligned with the Allies. These nations opposed the Axis powers and worked together to promote their collective interests during the conflict.

The USSR did not break up and become Russia again. Thinking Russia and the USSR were the same, is a common mistake. Russia was just part of the USSR, along with many other countries. Russia was the largest of the countries that were part of the USSR. In 1991, the USSR broke up and these countries, including Russia, all became independent.
The USSR was a Russian empire. Most countries in Eastern Europe used to be part of Russia, and was under Russian control during the Soviet Union's reign. Estonia, Latvia, Lithuania, Belarus, the Ukraine, Moldova, Georgia, Armenia, Azerbaijan, and Kazakhstan were all part of the USSR and Finland achieved independence just prior to the formation of the USSR.
Parts of the USSR (Russia) were occupied by Germany during the war, but at no point did Germany formally annex or obtain any part of the USSR.
The countries that used to be part of the USSR and are now members of the European Union are the so-called Baltic countries: Estonia, Latvia and Lithuania.
Not all All Eastern European Countries were part of the Soviet Union (USSR) of them. The following European countries were part of the USSR before its disintegration in 1992: Russia, Estonia, Latvia, Lithuania, Belarus, Ukraine, Moldova. Plus the three Caucasus countries which are sometimes considered part of Europe: Armenia, Georgia, Azerbaijan.
Lithuania and Latvia
During World War II the primary enemies of the Allies (of which we were a part) were Japan and Germany. There were also other minor Axis countries which were part of the war.
Countries which used to be parts of the USSR: Russia, Ukrain, Belorussia, Moldova, Latvia, Lithuania, Estonia, Georgia, Armenia, Azerbaijan, Kazakhstan, Uzbekistan, Turkmenistan, Kyrgyzstan, Tajikistan. No country used to be a part of Russia. Russia itself was a part of the USSR.

Latvia was not an independent country during the Cold War. From 1944 to 1991 Latvia was part of the Soviet Union (USSR). So it was on the side of the USSR, because it was the USSR.
