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.
I suspect if Germany had prevailed in World War II, German would now be the universal language, Germany would be a superpower today, and they would have nuclear weapons. There would likely be no more Jewish people nor would the State of Israel exist. The borders of European countries would be very different, as would the Middle East, Africa and India. India would be different because it would have no longer have been part of the British Empire.
Africa and the Middle East would be different because Hitler’s racism may have led to his exterminating Muslims and other religious groups and people not of the Aryan race.
