Rules: No PODs before 1930.
The superpowers can be any country.
"Superpower" is defined as any country with at least continental, if not global military, economic, political, cultural and ideological reach. While USA and Soviet Union seem to be the obvious ones, what other contenders are there? A reinvigorated British Empire? A victorious Nazi (or more likely non-Nazi expansionist) empire? Japan? Canada? :D
