How was World War 2 a continuation of World War 1?

Hitler was mad that he lost the Rhineland/ treasury he rallied his people and made them believe that there was a master race. (ayrians) he thought that anyone else who wasn't an ayrian was inferior so they should torture them.

This led to tensions increasing and then he invades Poland
