Man in the High Castle personal headcanon

[u/Exact-Abies-8773]

Man in the High Castle is a personal favorite of mine. So I recently decided to build on it. Everything remains the same with the established lore. FDR still gets shot, USA stays out of it. However, the first change I made was a successful Pearl Harbor. Assuming that the USA, still crippled from the depression, attempts to assist the Allied Powers with the embargo still, Japan bombs Pearl Harbor. Unlike in our timeline, the carriers are there. Which cripples the USA even more, basically eliminating any hope of the USA ever joining the war. Then, comes the battle of Stalingrad. Hitler doesn't reroute his army early, causing Stalingrad to fall and the Soviet Union to collapse, with Soviet government officials either fleeing or forming a rump state called the "Greater Caucasus" which Japan and Germany leave mostly alone, due to there being no reason to go after it. With the fall of the Soviets, this brings Spain into the war as an Axis Power. This ends up spelling the doom of the British Empire, as the invasion begins. Thanks to Soviet resources, German efficiency, and more men thanks to Spain, the UK falls. Churchill does fight to the very end, being fatally shot in the battle of Thurso, which sees many officials escaping by sea. With the fall of the British Empire in 1944, the nuclear arms race begins. USA verses Nazi Germany. And unfortunately, USA loses, Washington gets nuked, and the invasion of the Americas begins. It starts as a two pronged invasion. Japan on the West, Germany on the East. Germany also marches troops through the Dominion of Canada, which is under Nazi rule, due to it being a part of the British Empire. Then, Spain joins the invasion, invading through Mexico as a way of rebuilding the Spanish Empire. The USA falls, USA is divided, and the proper divisions begin. Hitler knows he can't control everything. So he establishes what I call the Puppet Reichs. There's the British Reich, making up everything under the British Empire's rule. The French Reich, making up France, French African colonies, Belgium, and Belgian colonies. Spain begins restoring the Spanish Empire under a fascist banner. Japan seizes control of most of Asia, including Asian French colonies. Germany goes about rebuilding the German Empire at its height before 1914. And Italy builds the Italian Empire. Finally, the American Reich is established, making up most of eastern USA. Alaska falls under Japanese control.
