Constantinople never redeemed because of Britain

[Herr Abubu]

Why did the Vatican wanted Constantinople to stay with Muslims and not with Orthodox Christians?

Because the Vatican and Constantinople, Catholicism and Orthodoxy, are bitter, hateful enemies. Manhattan goes on to show how the Vatican had wanted to weaken Orthodoxy, particularly as embodied in Moscow, the Third Rome, so the Orthodox could be converted to Catholicism. The Vatican's relations were for a time very friendly with the USSR, to a large extent because they kept Orthodoxy down while allowing Catholic (and Protestant, which the Vatican didn't like) influence, which the diplomacy of the Vatican made sure of.

I wish I could have taken part at the reconquista of Constantinople. And I wish they turned Hagia Sofia back into a Christian church, after demolishing the minarets and replacing the crescent with a cross. The butthurt it would have caused to Turks and towelheads everywhere is worth it. Of course most Turks would have been repatriated to Asia Minor and replaced with Greeks.
