Let's first focus in this part. Iran controlling the Transcaucasus requires a PoD going all the way back to the early 19th century.
Poland controlling what appears to be most of Germany east of the Elbe and East Prussia... Doable if the USSR decides to i) remove the entire German population from their sector, or ii) create a Brandenburg Gate Crossing scenario where the Germans become a minority in their own land.
The green blob in between Germany and Switzerland is Bavaria (limited by the Danube however)
Alt-Slovakia and alt-Hungary/Croatia/Bosnia could only be formed either by a complete assimilation of Hungarians, or by a worse Trianon coupled with an aversion of Yugoslavia altogether.
Also, it appears that Franz Josef Land is Norwegian here. Have Norway instead of the USSR control it by 1926.
Alt-Macedonia controlling both Albania and the Western Thrace, as well as Bulgaria with Eastern Thrace can be the result of a more disastrous Balkan Wars.
Moldova as Bessarabia is easy. Let the USSR give them the Budjak instead of giving it to Ukraine, and done.
Independent Pakistani Balochistan can be the result of a different Partition of India.
That land between Iran and Afghanistan... Some sort of Iran-unfriendly buffer state?
Kyrgyzstan, Tajikistan, and Tashkent under one state can be the result of a different split of Central Asia.
Lebanon controlling the northern half of Israel, and a larger Transjordan is not impossible, but then which one would end up as the destination of the European Jewry?
