IIRC list of popes is same until John Paul II. IMO this is bit odd since I can't see Wojtyla becoming pope ITTL since Poland ws already free in 1978 and communism wasn't anymore around so there is not reason for Wojtyla's choice. John XXIII, Paul VI and John Paul I anyway make some sense I think. But I am pretty certain that OTL JPII should had been butterflied away.
If that’s true then that’s honestly a little disappointing IMO. With such a radically different world by the 50s, when Pius XII dies there’s not going to be the same conclaves. For example in 1958 alone both Gregorio Agagianian and Józef Mindszenty, two cardinals from communist nations who openly opposed the dictators of their respective nations like John Paul II could’ve plausibly been elected. More importantly, IMO it would’ve been a good stylistic choice for FoM as a John Paul II type figure who opposed fascism (ITTL I’d imagine it’d be nazism due to fascism’s better reputation in the TL) and communism. Both could’ve inspired opposition to communist totalitarianism and it would be interesting how they interact with the world, fascism, communism, and how they change the Catholic Church. Who knows maybe a Pope could help transition Italy to democracy? There’s just a lot of possibilities I think where missed and considering the butterflies, past Paul VI it’s unlikely any of the popes stay the same.
I agree that John Paul II would be butterflied away as the Vatican wouldn’t need to worry about communism after the collapse of the USSR. I looked at alternatives to John Paul II before but this thread isn’t the place for that.
At the end of the day though it’s the author’s TL and I respect his choices. If Sorairo didn’t want to cover it or change the popes then that’s his choice and it’s fine to make that choice. I’d rather have him write about what he’s interested. In the end this post criticizing one minor aspect of TTL, I hope is just considered to be in good faith. The TL is still very good and very engaging and worth the read IMO. And admittedly the Popes story wise don’t have that much of an impact compared to South Africa, America, the USSR, Italy, etc.
