There have been many kinds of literature on how the world would have been if the Axis power won the Second World War.
Some people believed if Germany had prevailed in the Second World War, there would have been a complete genocide of the Jews.
German would have become the universal language; the United States would seize to exist as Hitler had big plans for them.
People believe there would be a restriction to speech because they believe the German will plant cameras and drones in all the countries.
The world would have been divided into two as the German would have defeated the United Kingdom and the Soviet Union. In contrast, Japan defeats the United States and would have owned part of China and Pacific Asia. There would have been the enslavement of Eastern Europe and people that are not from the Aryan race.
