In December 1942, the "Freiburg Circle" who were continuing their work helping Goerdeler develop a constitution submitted the "Great Memorandum" to Goerdeler for the proposed post-Nazi German government, which also included "Proposals for a Solution of the Jewish Question in Germany". The "Proposals" rejected Nazi racial theories but stated that after the overthrow of the Nazis, German Jews would not have their German citizenship restored but be restricted to living in ghettos and be allowed only minimal contact with German Christians, and he called for continuing the Nazi ban on marriage and sex between Jews and German Christians. The Israeli historian Saul Friedländer used the "Proposals" to argue that Goerdeler was anti-Semitic, and that his differences with the Nazis on the "Jewish Question" were ones of degree, not kind.
