Question

What was the United States' major concern about their former ally, the Soviet Union?

Answer 1

United States and Soviet Union were the two most powerful, or the superpowers of the world before the world war.

However there existed a cold war between them and each country feared of bombing each other as both as nuclear weapons which was as fearful as death.

Despite all the possible efforts, the two superpowers could not maintain good relations and ended up bombing with the soviet union's fall.
