It's a fairly common question asked "What if the Soviet Union still existed", which often means the Eastern Bloc also still exist as they were including the Warsaw Pact nations: Bulgaria, Czechoslovakia, East Germany, Hungary, Poland, and Romania (perhaps also Yugoslavia and Albania, though that's a bit trickier). But I was wondering if there are any stories that tackle what a modern world split between two rival Blocs would look like. Any stories that cover this?
