Maybe not the best analogy, but other cruel regimes copy their methods to this day. How is it implausible chunks of the Empire survived long enough to rebuild? It was a good enough idea for the EU…
That was actually one of my favorite parts of the film. I loved that the Empire was still around in a similar form. The Nationalist government of China that the Communist Party overthrew remained intact for decades with a government set up in Taiwan. I like that the Emperor’s death in Jedi didn’t end the Empire, I mean heck, Caesar’s assassination didn’t end Rome.
