3. Soviet Union
Communism is responsible for millions of deaths – more, even, than Nazi Germany in just the Soviet Union alone. Communists such as Josef Stalin, Mao Zedong, Pol Pot, Nicolae Ceausescu and others have killed millions of people. But The Soviet Union stands out as the worst. Stalin, alone, killed 10-60 million people. The Soviet Union was probably one of the U.S.A’s greatest foes. Living under Stalin put even the most average person into a state of constant fear – this, alone, makes the Soviet Union worse than Nazi Germany, in which the majority of Germans felt a certain level of safety as long as they supported the Nazi concept.
