What we learn from this postscript is:
A) Fascism is inherently self-defeating, which means that fascist systems have to constantly reform to remain intact, and those fascist reformers are sometimes mistakenly perceived as good people rather than as the means by which fascism perpetuates itself.
B) Successful corrupt systems, whether fascist or not, usually build a facade to legitimise themselves; this facade does not match how power actually works and isn't meant to, but distracts from it and conceals it.
C) Because fascism is so deeply tied to aesthetic, fascists are very vulnerable to this sort of facade, either believing in their own or railing against other peoples'.
D) Fascists have shit for brains, even the smart dangerous ones, and so they tend not to understand any of this.
