The way I picked up history I always condidered the Holocaust a crime of the Nazi's. I'm wondering if I am mistaken - is it more accurate to consider the Holocaust as a European crime?
Various European governments collaborated with the Nazis and served as satellite states of the Third Reich. Jews were transported inside the countries of Europe into concentration and death camps in a well oiled bureaucratic system. Many bodies and governments had knowledge about a systematic extermination and rounding up of whole historical Jewish communities and did not intervene. Many other governments turned back ships loaded with Jewish refugees.
The Third Reich might have risen in Germany, but the ground was well prepared across the continent for such a large scale operation against Jews. centuries of anti Jewish sentiments and activities did not die out with the European enlightenment and the emancipation. The birth of modern Zionism for example was the direct result of exclusion, discrimination, and persecution of Jewish communities and individual Jews.
The 20th century saw decorated Jewish veterans of WWI being stripped of their honour and rights in Germany, Jewish officers (Dreyfus affair) being lynched by an anti-Semitic media for spying crimes they did not commit, and common Jews being exiled to gulags in Siberia supposedly for being political dissidents.
That is pretty much the story of my family in Poland. My grandfather was exiled to Siberia by the Russians for no justified reason, his family was turned over to the Germans by common Poles they grew up with, and murdered almost in its entirety in Sobibor death camp (according to our information).
My grandfather's key for survival was serving in a Polish fighting force under the British high command.
