Russia and the United States don't get along very much. Because America got all paranoid though, foreign policy has changed with other countries, and America has turned from not engaging in foreign affairs to protecting freedom and democracy and stopping the spread of the "red" disease, of communism. Well that's their story.
The Soviet Union eventually disbanded.
The good news, is that because of that, many countries look to America for help in distress, and receive it most of the time, and now there are global laws regulating how many nuclear weapons countries can have compared to their population. So hopefully the world won't end in a Nuclear holocaust. Hope this helps kiddo.
