That is what I though but wanted to make sure. Yes there is a difference in the Iron curtain with Soviets not advancing as far west iOTL. We will have the whole section of the WWII, which will provide a picture of the extent that Germany was able to expand east and the Soviet counter act. The end of the war in Europe was one that caused major distrust between Soviets and West (more than iOTL) leading to another major conflict in Europe at end of the 1948 called the "Iron Curtain Crises". Sorry but at this time cant divulge the exact borders, we will discuss at end of the 1940s - War years section.Yes. I'm guessing it's further east than OTL due to the fall of Moscow disrupting the Soviets?
