How realistically small could the Eastern Bloc have been during the Cold War? I believe at several opportunities, Hungary, Poland, and Czechoslovakia could have been reached first by the Allies based on change of strategy during WWII. Is it possible to have Bulgaria and Romania outside of the Eastern Bloc as well? Maybe having Turkey join the allies and using it is a jumping point into the Eastern Balkans? The Soviet Union wasn't invaded because of some unforseen problem in the Balkans or Hitler dying, but decides to make an independent war effort once progress begins to be made by the Allies? Then the allies decide to reach Bulgaria before the Soviets take Romania?
