If we are talking post WW1 breakup of the Ottoman empire (Which seems to be the best case post 1900) then I dont understand how Greece gets Constantinople and the Straits but no territory on the Turkish Aegean Coast like Samos.
Also Cyprus would join any Enlarged Greek State.
Italian Anatolia is highly unlikely. Maybe an Italian Area of Influence but direct Italian control beyond Rhodes and some Aegean islands isnt very likely.
What the Hell is that Rump State Arabia?
Armenia and Kurdistan seem plausible seeing as that was the territory to be allocated to them at Sevres.
The kingdom of Persia would get parts of Irak. The Sunni and or persian Areas.
The renaming Arab States Syria, Arabia, Parts of Irak, Transjordan and Egypt should form some sort of UAR under the influence of a France or UK.
This would be to counter Israel, Kurdistan and Persia.
Any Israel former earlier then OTL would be way stronger and larger then OTL. No Holocaust means huge surplus of Jewish Immigrants. bigger population means more land, stronger economy, bigger Military. The current Israel looks like the proposed borders of the Peel Commission.
Everything israel did IOTL was with 6 Million less jews in the world to support them. That population back in the equation means a stronger Israel.
Republic of Russia? That owns the Ukraine and most of the Caucus?
Russia should be broken up into different states for the various Ethnic Homelands and Russia/The Slavic areas should be in a state of warfare similar to the warlords period in China.
No stable democratic russia.
