I could give a crack at it later today. I'd just need a translation.
I'd say the partitioning parties are the following:
- France: England/UK in Normandy-Brittany, Germany in the east, Italy in the southeast and Spain in the southwest
- Italy: France in Piedmont and Sardinia, Austria in Veneto, Yugoslavia in the east (around Ancona), and Greece in the south including Sicily
- UK: Norway in Scotland, Germany in Northern England, France in southern England and the United States in Ireland
- USA: Japan in the west, Mexico west of the Pecos River, Spain in the south and the UK (or rather Canada, most likely) in the northeast
- Germany: Denmark in Schleswig-Holstein and Mecklenburg, Poland in the east, Czechoslovakia in Saxony and France in what remains in the west (which I find weird but well...)
