''The Man with the Iron Heart'' is an AlternateHistory by Creator/HarryTurtledove. After the German defeat at the battle of Stalingrad, Heinrich Himmler is convinced by UsefulNotes/ReinhardHeydrich to help him set up a [[TheRemnant terrorist resistance]] in case Germany loses the [[UsefulNotes/WorldWarII war]]. Once Nazi Germany loses and is occupied TheWarOnTerror begins [[RecycledInSpace in Germany]] which eventually leads to Allied troops withdrawing and leaving West Germany as a democratic, un-Denazified country where the Nazi party is now legal.

Not to be confused with ''Film/TheManWithTheIronHeart'', which is a historical/{{biopic}} film about Heydrich and his assassination.

* AllohistoricalAllusion:
** The continuing US occupation of Germany, the rampant insurgency from the German Freedom Front, a draft, and the anti-occupation movement from America [[TheWarOnTerror rings any bells]]?
** Diana [=McGraw=] appears to be based on [[http://en.wikipedia.org/wiki/Cindy_Sheehan Cindy Sheehan]], although leading a more successful anti-occupation campaign than Sheehan.
** The GFF kidnapping and filming of American soldier Matthew Cunningham and Soviet Soldier Nikolai Sergeyevich Golovko, which their captors demanding their respective nations to withdraw from Germany and the films are released to the public is based on the "beheading videos" released by Islamist militant groups during the War on Terror.
* BlackAndGrayMorality: The Nazis are horrible but so are the Soviets and to a lesser extent everyone else.
* DownerEnding: A joint American-Soviet force managed to find Reinhard Heydrich and killed him while he tried to escape, but this doesn't end the insurgency. The Nazi resistance is now led by Joachim Peiper. While the Soviets remain committed to the occupation and to crushing the resistance, the Americans and British complete their withdrawal, leaving the Nazis ready to reemerge.
* TheDragon: Reinhard Heydrich's second-in-command Joachim Peiper.
* ForWantOfANail: Reinhard Heydrich survived his assassination by Czechoslovakian freedom-fighters in 1942. His survival allowed him to form his plans for the aftermath of Germany's defeat and creating the German Freedom Front.
* HistoricalVillainUpgrade: Reinhard Heydrich, but only slightly. Heydrich was shockingly, monstrously evil (he was one of the chief planners behind the Final Solution, and chaired the conference where it was decided upon) and there was a very, very good reason why the British made him their first target for what was supposed to be a campaign of assassination. When the British-trained Czech and Slovak assassins succeeded, however, the Nazis responded by totally destroying the towns of Lidice and Lezaky, murdering at least 1,300 people. This put an end to the UK's assassination scheme.
* TheRemnant: The German Freedom Front, aka the Werewolves.
* MarriedToTheJob: Diana [=McGraw=] becomes too involved in politics that once the occupation is over, she isn't so sure that she is satisfied in going back to being the [[StayInTheKitchen traditional housewife]] and already her marriage is close to breaking apart [[spoiler:especially when she had a brief affair with a local San Francisco politician named Marvin (whom she was so disregardful of that she can't remember his last name)]].
* MonumentalDamage: St. Paul's Cathedral, Westminster Abbey, and the Eiffel Tower are leveled by the GFF.
* RecycledInSpace: The entire premise of the story is essentially TheWarOnTerror set in post-World War II.
* ShoutOut: At one point, Heydrich comments that "Tommorow belongs to us", a reference to the song "Tomorrow Belongs to Me" from {{Theater/Cabaret}}, which has since, in RealLife, become associated with Neo-Nazism.
* SupervillainLair: The GFF's Alpine Redoubt.
* SympatheticPOV: Turtledove uses this nicely to avoid [[StrawmanPolitical Strawmen Political]], either for or against the war. The pro-war side is represented in particular by Weissberg, a decent and dedicated Army intelligence officer who sees the Nazis as just as much of a threat as when Hitler was still in charge, and believe that cutting and running will just lay the groundwork for WorldWarIII. Meanwhile, the other side, represented best by Diana [=McGraw=], the Cindy Sheehan {{expy}}, and Congressman Jerry Duncan, are correct in the fact that the Truman administration doesn't seem to be doing a good job of things, and that there doesn't seem to be a plan for victory. On the one hand, Truman's predictions of rockets aimed at New York, which Duncan and [=McGraw=] dismiss as "Buck Rogers style fantasy", are, as the reader well knows, all too accurate; however, Duncan and [=McGraw=] have no way of knowing this.
