it is easy to check, Jews were collaborating with nazis more than local populatins…and not poor one, but Jewish elites….
In Poland it was Capital Offence to help a Jew, not only helper, but whole helper’s family would be “wiped out” and many were still helping and wondering why Jews denouncing each other !!!
Dr. Ewa Kurek published many books about Jewish Collaborations that !srael and !srael lobby trying to “shut down” but so far lost many cases in Courts in USA because they can win with facts and evidence !!!!
