A little bit more historical background:
Yet Poland also produced the greatest number of rescuers. To date, more than 6,350 non-Jews in Poland have been recognized by Yad Vashem, more than any other country, Israeli Ambassador Zvi Rav-Ner said.
Yad Vashem’s statistics show that after Poland, the Netherlands has the most number of “righteous” — 5,204 — followed by France’s 3,513.
The Customer Review of the Compilation contains a lot of historical information:
There is also a list of 450 Poles known to have been murdered by the Germans for helping Jews. This list includes the names, ages, and place of domicile of the Poles. Although western-European benefactors of Jews could be put to death in individual (especially extreme) instances, it was only in German-occupied Poland that there was an automatic death penalty for the slightest assistance to Jews
Unfortunately, these historical facts are ignored by what was the History Channel and PBS (I avidly watched / watch both).
