See, this is why I don't like to write pieces taking place in our current real universe. I might involve Earth from time to time, but, my writing has its own separate universe where things work just a little differently.
I just think it would be too much work to ever try to write something based on real events. That's not to say there aren't plenty of interesting events in our history, just nothing I can really be bothered to try to research and remember.
Harry Turtledove's giant "American Empire" alt history series.
Some of his other work like "Guns of the South" worked perfectly for me, time travelling South African Racists from the Future travel to the Confederacy and give them blueprints for manufacturing simplified AK47 Assault Rifles, using contemporary materials.
But American Empire, I just couldnt quite suspend belief. The premise is, the South won the civil war, now there are 2 "Americas" and World War One lumbers up with a massive change, later followed by a Second World War.
And basically, what he did, is he took every significant event of WW2, and what led to it, and he relocated it faithfully to the United States, and that just did not work for me, not to mention other issues. Instead of death camps for jewish people in Germany and Poland, we have death camps for african americans in the Confederacy. The whole point of changing an important event in history is the future from that point is then yours to play with, strictly adhering to the timeline and events of real history, just moved to a different country just seems a waste of imagination
One issue that did not gel for me: The new World War One.
The "Central Powers" A vastly smaller USA, Imperial Germany, Austria-Hungary, Ottoman Empire, Chile, Brazil, Paraguay, Bulgaria, Armed Socialst African American groups, operating as 5th columnists in the Confederacy.
On the "Entente" side
The Confederate States of America, The British Empire inc the Dominion of Canada, The French Republic, The Russian Empire (no revolution), Belgium, Portugal, Serbia, Imperial Japan, China, Mexico, Argentina, Mormon Rebels in the USA.
WW1 ends with the Entente forces comprehensively and utterly smashed by the Central Powers. The United States, hammers the CSA to shreds (believable) whist also destroying the Canadian and Imperial Forces in Canada, and occupying the whole of Canada at the same time (now come on....)
And that did not work for me at all. The sheer size of the British Empire, and the forces it could call on, the European side of events is pretty much as real life, and that still left one of the largest, awe inspiring Navy's in all of History, the Royal Navy, and its Colonial allies, Royal Australian, Royal New Zealand, Royal Canadian, and so on to control, and remain the dominant naval force everywhere, from the Atlantic to the Pacific In naval terms, iirc, WW1 was fairly low key in Europe, the Kaiser's navy was nothing in comparison to the British Empires.
I can go for a German victory in western europe, but losing Canada? The British Empire, with that incredibly powerful Navy, that dominates every ocean agreeing to give up half its colonies to the US? Naaah
