Personally i think the Saudis are also screwed, Sorario specifically said that its questionable wether the arab world surrvivies at all so Id think that includes the Saudis in the general screwedness.
A lot to unpack, but I really like this update.
A Hohenzollern Germany without Brandenburg or Prussia is a fun fun fun concept indeed. Prussia being dismantled makes sense - I recall that even during the Weimar era there were pushes to create a separate Rhineland Free State separate from the Prussian Free State. There's quite a bit of mental gymnastics going on it seems... Prussianism is still being considered a cause of German militarism TTL (I think) and thus the imperative to dismantle/destroy Prussia is still there, but the WAllies are sticking a Hohenzollern on the throne.
Frankfurt as West German Capital is powerful. OTL they stuck it in Bonn instead of Frankfurt because the intention was that Germany would be reunified one day and the capital would go back to Berlin. The concern/thought process was that if the capital was put in Frankfurt, a big city with a lot of historical legitimacy, the capital would not go back to Berlin should the country ever reunify.
Adenaur OTL hated anything Prussian. He said he disliked the "Asian steppe" east of the river. He was so anti-eastern that he complained about East German who moved to West Germany. He wanted to swap West Berlin for Thurgingia, Schwerin, and Schwerin. The Monarchy vs Republic issue may foster stronger division of identity between east and west TTL.
@Herr Frage I saw that you raised the question of West Germany's land and resources compared to OTL. IIRC most of the Germans in the ceded territories were sent to West Germany OTL. East German retaining Silesia south of the Oder and (I think) Stettin probably balances West Germany having Thuringia and western Saxony as far as population goes. As far as natural resources go, West Germany has more.
There's also a question of what happened to the Germans of Hungary, Slovenia, and Czechia TTL. If Germans in those countries were not expelled or fewer Germans were expelled, then West Germany has fewer people.
The Royal Houses of the Kingdoms Bavaria, Saxony, and Wurttemburg are restored but the states themselves aren't made into Kingdoms? How does that work exactly?
What are the internal divisions of West Germany? Are they more similar to OTL's West Germany/Germany, more similar to the Weimar-era divisions, or something else? If, for example, the boundaries are more similar to OTL West Germany's, then there is a question of where the Wittelsbachs are Kings (only in Bavaria state? In Bavaria State and the Palatinate? If they're Kings of Palatinate is that just palatinate or all of Rhineland Palatinate? etc.) and where the House of Wurrtemburg is King (only in Wurrtemburg or over the entirety of the state of Baden-Wurrtemburg?). Do the Hohenzollens get a special status in the province of Hohenzollern?
What is the status of Saarland? The same as OTL's?
Do you hear that at the distance?
It’s the Dawn of the Red Tsar. Poor ********, they’re dead.
