The only real issue I see is that I had Germany invading the Baltic in '57. If you want to move it to '56/'57 though, that was the end of the German Civil War, and I can just retcon out the part about people protesting re-invading the Baltic alongside Poland.

Edit:
Also, fixed the map. (I'm pretty sure. Like. 95% sure. It's easy to lose track of which provinces go where when zoomed in on this.)
