What is this Soviet Union thou speak of?

1. Hungarian Republic/[i]Magyar Köztársaság[/i]
2. Kingdom of Serbs, Croats and Slovenes/[i]Kraljevina Srba, Hrvata i Slovenaca[/i]
3. Czechoslovak Republic/[i]Československá Republika[/i]

Oh, also, what's that state around Proskuriv? In addition, aren't the Saarbeckengebiet and the Tannu Tuva a little bit anachronistic if this is Jan 1920? And are Mountaineer borders not a tad too small for the date?
