D) Reestablished a harsh dictatorship

Explanation:

After the World War II ended, the Soviet Union reestablished a harsh dictatorship. The person responsible for this was Stalin. Stalin was a leader that had no tolerance whatsoever to people that were opposing him, or he considered that they may be a problem in the future for his power. Because of this, he started to systemically send people to prisons, concentration camps, or ordering their murders. He was the figure in the country that had all the power, and no one was able to top him. The end result of this was tens of millions of people ending up dead and displaced in the Soviet Union.
