Normally for me a Nazi-wank is Nazi Germany even surviving at all, so I decided to do a different take on a Nazi-wank from the one I normally would use.
It's 1975 and a decade has passed since the violent collapse of the GGR. For 25 years the GGR ruled over Northern Africa and Western Europe and for 23 they ruled over European Russia and as you can expect the aftermath of pure horror. After Hitler died in 46 (a drug overdose) Speer managed to wrestle control of Germany proper after a brief power struggle. A "reformist", Speer quickly came to blows with Himmler and the SS and ignited the First German Civil War in 1948. The bulk of the German Army stood by Speer who controlled most of Germany proper and most of Western Europe. Himmler and the SS controlled most of German occupied Russia (which was still a bloody sore for the Germans because even though they had knocked the Soviet Union out of the fight they still had to hold the region) and Nazi occupied Africa. With the SS spread thin across Nazi occupied Russia and Africa and most of Germany's Fascist allies backing Speer the war was destined to see Himmler and his radicals lose. Unfortunately for the people of SS controlled Russia, Himmler began widespread use of chemical weapons against the enslaved Slavic populous and even against German colonists and German soldiers. The chaos that engulfed German occupied Russia after the fall of the SS would never truly end as the German army was stretched the breaking point having to occupy the massive landmass. Just as in Russia the SS occupiers of Nazi Africa began full scale chemical attacks against the native population, though here they had already been enacting a policy of extermination. German reoccupation of Africa was very thin after the chaos of the German Civil War and German authority was never fully reimposed on the brutalized region. After Himmler's death many of the Nazi hardliners were forced to a back seat to Speer's technocratic reformists.
Across the globe the Pacific War between the United States and Japan saw the brutal invasion of the home islands by the United States after military hardliners had refused to surrender after the US had dropped two atomic bombs. The brutality of the situation of horrific and the cost in human life was massive. The US would drop three more atomic bombs Japan after the start of the invasion (a fact that would result in the death of countless American troops do to radiation poisoning). After the American deployment of the Atomic bomb the Germans began to scramble to try and build their own, but even the best estimates put creation of an operational device as far away as 1956. The German development of the atomic bomb was hampered by the state of the German economy which had been temporarily crippled by First German Civil War. Parasitic in nature the German economy had been cut off from the resources of Russia which had brought an abrupt halt to many of the extravagant spending projects that Speer's technocrats had been supporting. The situation only got worse as time went on and the German economy began to spiral out of control and entered an economic depression. With the decaying of Germany the Nazi hardliners began to grow more bold and in 1955 they make a play for the government and kill Speer. Though Speer was killed the Speerists still retained control over much of Germany. This would spark the Second German Civil War. For three years the Second German Civil War will tear Germany apart, before the hardliners win the war. The Nazi fanatics that came to rule the GGR as an oligarchy started shipping Frenchmen to North Africa after they start ramping up liquidation of the Algerian population and they started forcing German families to move east to both cities that the Speerist's had begun building in Russia to try and stabilize the German economy and to become "noble" farmers. Few of these families forced to live in Russia can afford to live in the cities and those that are sent to the country side are subject to bandit raids and attacks by Slavic freedom fighters. Faced with being forced out of Northern France, the French begin to rise up again and are brutally suppressed by the Germans marking the disintegration of the Vicky government and the restructuring of France to be run in a manner similar to German occupied Russia.
With Germany going batshit insane the other fascist nations of Europe started worrying about the Nazis trying to invade to take resources to prop up the collapsed German economy. Italy has been silently working on its own atomic bomb and hasn't had to deal with constant civil war like Germany has. The Bulgarian Empire, Italy, Romania, Hungary, and Croatia had formed a secret alliance in which if one was attacked by Germany they would all declare war on Germany. Over the next few years Germany would become ever more repressive and many German citizens would find themselves the targets of the regime. The depressed economy, widespread political repression, and ongoing famine would ultimately lead to the Third German Civil War in 1963 which saw the total collapse of German authority in Europe by 1965. Without the artificial backing of the Nazi government France collapsed into a bloodbath of chaos as numerous powers groups tried to assert themselves...the situation hasn't really gotten much better since then. British peace keeping forces occupied part of coastal France in an effort to stabilize the situation, but have had little effect on the French interior. The French government in exile was accepted back by the Algerian French and some of the southern French, but their power doesn't extend far beyond the coast. Belgium collapsed as well, though a bit more neatly than France. Italy was forced to give up Ethiopia and is locked in a war to retain control of Greece and Albania. The Soviet Union has been to busy trying to put down revolts in Central Asia to try and conquer the warlord states that makeup European Russia. The American occupation of Japan has finally come to an end (or at leas been reduced) and the Japanese finally have a civilian government rather than being run by the US Army. Currently Germany is divided between the fascist (but not Nazi) South German Democratic Republic and the authoritarian People's Republic of Germany (not as communist as its name sounds).
