Basically, the world would be a totalitarian/facist government run by the AXIS powers.
Canada
Communism is not totalitarian. A Communist world would have no government or classes or money.
The allies had a huge number of supplies and arms on their side when they entered World War II. They also had air supremacy which was one of the major turning points in the war.
They were still fighting the Germans
Totalitarian
Germany (Adolf Hitler) and Russia (Josef Stalin). Many people believe Italy was a totalitarian government, but historians aren't sure whether Mussolini intended to have complete control over the people. Another possibly totalitarian government was Japan under Hirohito's rule. However, most people don't believe it was a totalitarian government.
National Socialism
As soon as the US entered the war in December 1941
Italy entered WWI in 1915 on the side of the Entente (Allies).
If there was no government, the world would be a totalitarian. The world would not have as much protection from the police and everything would be a disaster. No one would be able to control what happens in the world.
