So i'm curious,did anyone find a map that represents the world's situation and borders just after the liberation of Alaska,a few months before the Great War?

Look at map of the world before the fall of the USSR. Canad and Mexico as part of the United States... other than that it would be anyone's guess. The nations of Europe at war with themselves and the middle east. I believe the Fallout bible mentions that China annexed a bunch of it's neighboring countries. Africa I would imagine remained a pawn of European powers. South America Australia would have been normal I guess, possibly under pressure from China.

The UN still existed, I don't think Africa would have been a European pawn, at least until the resource war started happening.

I'd like to see a map of China during October 22nd, 2077. See how much the US actually took.
