You have identified the indelible shame of the occupied countries. The Nazis would never have achieved the “success” they did in exterminating European Jewry without the meticulous civil record keeping providing the identities and locations of all Jews and the enthusiastic support of civil authorities in rounding them up for deportation.
The truth is that the governments of the occupied countries were all too happy to help the Germans get rid of their Jews. Those pogroms had just gotten so tedious.
Not every country. Notably Denmark. And certainly not all officials. But way too many just kept “doing their job” in a time when doing so meant collaborating with great evil.
To be fair, it’s easy for you and me to sit around and criticize those who went along to get along, and in many cases to just survive, when we don’t ourselves face similar dangers.
To my mind, only those who have resisted evil at great risk have a real right to condemn those who don’t. Surprisingly, in my experience most of those who have this right don’t use it.
I hope I would be one of the heroes, if I’m ever in a similar situation. But I won’t really know until I’m there.
