“Starship Troopers” the book is blatantly fascist, Heinlein became a fascist in his later years.
“Starship Troopers” the movie IS a parody of fascism, Verhoeven literally based the Starship Trooper’s symbols on Nazi iconography.
"Although some contemporary critics and audiences considered Starship Troopers to be an endorsement of fascism, Verhoeven said, “whenever you see something that you think is fascist, you should know that the filmmakers agree with your opinion.”

Also Sargon is just a fascist puppet.
