We all know that the EU owes its existence to the successful conclusion to WW2 w/Germany establishing economic and cultural dominance over Europe. What if the Axis had lost WW2? Would there be a supranational agency like it?
Well presumable for Germany to lose the USSR would need to push them out making the Europe a bunch of Soviet puppet states and I'm sure they would make some sort of supranational organisation something like the European Socialist Union but with a better name
