There are three known countries who used an authoritarian government during World War II. These are Germany, Italy, and Japan.Hitler was an authoritarian figure of Germany who believed that the Germans are the dominant race to rule the world. Mussolini also believed that like Germany, Italy has a role in leading Europe. In the East, Japan roused up fast as it tried to colonized countries in Asia. Hideki Tojo was the 27th Prime Minister who directed Japan's army on its conquest.
Due to Hitler's aggression it lead the military all over the world (from Asia to Europe to United States) to get involved and that's how World War II started. The reason all of them got involved is because Hitler's men were attacking our Allies. What really started World War II was when Japan bombed Pear Harbor in the U.S and in order for the U.S to end it was to bomb Hiroshima and Nagaski. When we dropped the atomic bomb, Japan surrendered.
So in order for the government to declare war is when a foreign country came by and attacked the U.S and kill a bunch of innocent of people.
Hope this helped :)
Have a great day
