Oxonian2006, my tone may sound a bit out of control but I'm not. Issues like this one are very important to me due to my own family history. Now, going further into your comment...unfortunately the knowledge of the occupation of Poland is not as universal as you may think. To many "the Nazis" does not mean the Germans as you suggested. Poland was not occupied by the "Nazis" who came from "Greenland or Mars" or "Nazi allies". Poland was occupied by the Nazi Germany or German Army (Wehrmacht) and at the beginning of the war also by the Soviet Union or Red Army. There were no other German allied troops occupying Poland unless you count Italian, Spanish and other Waffen SS troops marching to the Eastern Front. "The German-led Nazi occupation" you suggested is also incorrect, there was no such thing. Half of Poland was incorporated into the Third Reich with their citizens either murdered or expelled into the "General Government" which was created and %100 controlled by the Nazi Germany, nobody else. 
Therefore he "Nazi" is NOT a perfectly good word to use in this case and never will be.
Now, about the Polanski who in your opinion is not a Holocaust survivor. Well...he escaped the Cracow Ghetto on the way to the extermination camp. He would be dead otherwise. Then he barely survived hiding at sympathetic to him farmers barn avoiding the Germans who would kill him immediately if found. Every Jew hiding outside the Ghettos was immediately shot by the Germans. His rescuers and rescuers family was also killed.  I don't dare to suggest that you did not know about that. Every Jew who survived the war in Poland is a Holocaust survivor and it does not matter if he managed to survive Auschwitz, Cracow Ghetto or by hiding in the forest. They all survived that hell, so did Polanski.
