Yair Lapid, the current Minister of Foreign Affairs of Israel, is quoted as saying:
It is no coincidence that the Nazis created their center of extermination in Poland. They knew that the Polish population would help them.
Is that claim accurate? Was the "willingness of the Polish population to help" considered by the Nazis when deciding on the location of the concentration camps?
While there is a lot more to say on this subject (specifically responding to the quote), this answer to To what extent Poland was involved in death camps? by u/I_miss_Chris_Hughton may provide some background information.
Additionally, #GermanDeathCamps Ad Campaign, how accurate is it that the Polish didn't participate/aid Nazi Death Camps? by u/commiespaceinvader is excellent and includes a link to the previous thread I listed as well as another one.
