The Iron Dream is a 1972 Heroic Fantasy / Science Fiction novel by Norman Spinrad... sort of. The majority of the book is the full text of the brilliantly popular fantasy novel Lord of the Swastika, written by famed SF author Adolf Hitler; the rest of the book is a framing device setting up the world in which this alternate Hitler lives, and a concluding essay hammering the point home for those who didn't get it the first time through.
This book contains examples of:
Adolf Hitler — His alternate-history version illustrated for the pulps, then moved on to writing cheesy fiction.
After the End — A nuclear apocalypse has tainted the human gene pool.
Alternate History — A world in which Hitler moved to the US, got involved in Science FictionFandom, and died in 1954. Furthermore, Germany fell to a Communist revolution shortly after he left, and by the time of the book's "afterword" the Greater Soviet Union dominates Eurasia and Africa and is moving into South America, leaving only the United States and Japan as the bastions of freedom on the Pacific.
Contrived Coincidence: No sooner does Jagger decide that the Black Avengers have Outlived Their Usefulness when one of his men rushes in to breathlessly reveal that the leader of the group is conspiring with the Doms to launch a coup. Of course this mirrors the real-life Night of the Long Knives where the SA leadership was executed on trumped-up conspiracy charges.
Cosplay: It's mentioned that dressing up as the Sons of the Swastika is quite popular at sci-fi conventions.
Notable instances include a reference to a "holocaust of fire" and the protagonists warming themselves by a "heap of burning faggots."note The original meaning of "faggot" was a bundle of sticks, usually used for fuel.
The Dominators' symbol, prominently featured on their flag, is a yellow star.
Don't Explain the Joke — The Afterword outright explains every single subtlety and satirization in the book, which takes quite a bit of the fun out of writing entries for this page.
Feric Jaggar is horrified by the prospect of using nuclear weapons against Zind (because the fallout would taint the gene pool of the true humans).
Truth in Television in that Hitler was known to be very negative toward the idea of nuclear weapons. He was forced to conduct research into nuclear weaponry only because the Germans knew that the other Powers would do so. (Surprising? Likewise he was against police brutality and would not allow German police to carry guns or truncheons, which he considered demeaning to the public.).
It is surprisingly obscure knowledge, but Hitler was for a short time a member of a secret police and was tasked with infiltration of political movements. (He attended his first German Workers' Party (later renamed the National Socialist German Workers' Party, or Nazi Party) meeting as a police spy, liked what he heard, and joined up for real.) He quickly concluded, that brute force only causes the dissenters to hide and the covert intelligence operations are much more likely to yield good results. And his aversion to WMDs might have been caused by being wounded in a gas attack during Great War.
Hell-Bent for Leather — The tight black leather uniforms of Jaggar and his army are repeatedly described in loving detail.
Hitler's Time Travel Exemption Act — Of the "something even worse takes his place" type, despite the lack of time travel. The framing story is set in a world where Hitler never went into politics and the Nazis never mattered much. The Cold War is going very badly, and Europe and a lot of the rest of the world are probably much worse off than in our world.
Invincible Hero — Jaggar's one of these. Every decision he makes is right, his army wins against forces which vastly outnumber him, and even a little thing like a second nuclear holocaust can't stop him from creating his master race.
Keystone Army — The Warriors of Zind are all brutish mutants, but lack the brains to coordinate their own activities and rely on Dominator direction. Once Feric's forces kill the mutant masterminds, the Warriors begin attacking each other (and lose control of their bladders and bowels in their frenzy, and yes, this is usually described each time they do it).
New Wave Science Fiction: Like most of Spinrad's works of the time, this controversial and deconstructive work was very much a part of the New Wave.
One-Gender Race — Humanity, at the end. Since the Dominators' spiteful radiation bomb has ruined mankind's genome, cloning is used to create the next generation of ubermensch, who are all tall, blue-eyed, blond males.
Putting on the Reich — The alternate universe sci-fi fans do this with the uniforms described in the story.
Schizo Tech — The book starts in a post-apocalyptic world where steam-powered buses are common transportation, but swiftly moves through World War II-level weaponry before ending with cloning and interstellar spaceships.
There is not a single line of dialogue in Lord of the Swastika spoken by a woman. The words 'she' and 'her' simply do not appear at any point in the book.
There is in fact an appearance by the fairer sex in this book! Specifically:
"a dozen or more naked females shrieking and moaning; these were not true humans but pleasure sluts of the sort the Dominators bred for themselves in Zind—mindless creatures with oversized hips and breasts motivated solely by a boundless need for copulation."
A while after the last example, it is reported to Jaggar that nearly forty thousand pure human females have been found suitable for breeding with the SS.
All of this is, of course, intentional, reflecting as it does both Hitler's general lack of interest in women and Nazism's simultaneous encouragement of traditional female roles and tendencies towards postering overbearing masculinity. It also reflects a general tendency within many works of Heroic Fantasy to basically reduce women to scenery.
Space Jews — The Dominators of Zind, intentionally.
He also rejects the idea that Doms are an anti-semitic metaphor, as given the Soviet Union's persecution of their own Jewish population, no-one would seriously believe that Communism was a Jewish conspiracy.
Word of God — The framing commentator/literary agent says that Hitler in the alternative timeline died of syphilis, which slowly ate away at his brain. This accounts for (some of) the wild excesses of the later part of the novel.
