On December 25th, 1991 the Union of Soviet Socialist Republics (USSR) split into 15 countries, with the primary one being known as Russia. These countries had control of countless nuclear weaponry, from which the US gave economic aid for the weaponry to be given to Russia. All seemed well until 2000, where a powerful leader, Vladimir Putin, whom has shown interest within bringing back the power of the USSR. Putins actions in order to do this involve bringing all former Soviet states together once more, under Russias control. Currently Russia is invading Ukraine, with a nuclear threat to the US if it gets involved. Of course the US did get involved, training Ukrainian troops.
