Just curious, as far as I know they weren't so destructive to other cultures they occupied/puppet-ed after the war.
the complete destruction of Prussian culture after WWII?

In the FRG the GDR was criticised for having retained not destroyed some bits of the Prussian culture (such as this - a big no-no in West Germany). West Germans on the other hand were criticised for retaining all the old authorities, judges, professors et al.
