I think this is a dupe? I assume Poland is demanding similar reparations from Russia (as successor to the ussr) for the deaths and partitioning that occurred? Given that Poland was “moved west” as an outcome of the war, Germany should demand its lost territory back that is now in Poland. Poland can go to Russia to get its lost territory back so as to restore the pre wwii borders.
Or, Germany and Poland can call it a wash and Poland can go after Russian to settle its issues with the ussr.
