USSR stood for Union of Soviet Socialist Republics. There were 14 countries in the USSR. Russia was only one of them, but by far the largest and most influential. The countries returned to their original names, which they had before the USSR was formed. Russia is now The Russian Federation, since it is made up of more than just Russia. Ukraine is now Ukraine, etc. Each of the countries had a name similar to this: The Ukrainian Soviet Republic. Now is is simply Ukraine. Or the Republic of Ukraine.
