What was totalitarianism and how was it implemented in similar and different ways in Germany, Italy, and the Soviet Union?

Totalitarianism is where a leader decides that he/she wants a dictator-like leadership and wants to rule the nation with an iron fist. In Germany, he fought for the power of the Germans and put people of different denominations (Specifically Jewish people) under harsh treatment. In Italy Mussolini wanted to rule the World alongside Germany and put all of his people under harsh treatment to get there along with following the ideals of Hitler to become his ally.  Russia also wanted a lot of power but figured that the side of the US would be most likely successful in being powerful and because of this put their economy past the limit and kept the life of their people a secret from everyone else so that people would think they were all-powerful so that they would become all-powerful.
