The film is obviously parody and satire, but the novel is not. Heinlein's personal politics were a little more nuanced than some allow, but the book is full of unironic gun-toting square jawed heroes doing Sacrifice and Service and Discipline and all that good stuff, blasting big Commie beasties. It was written pre-Vietnam, which is some sort of a defence, but it's infatuated with war and the military and jingoism to a degree that'd make John Wayne blush. The primary target of the film's satire is its own source material, if anything.
