The real "Hitler-Style tactics" is not any specific historical injustice, it is the promotion of tribalism and nationalism, dividing people up into "us" (who have been wronged) and "them" (who did the wrong, and therefore deserve to be punished as a group) on the basis of race, religion, etc.

The opposite of Hitlerism is not Jews getting revenge on the Germans, it is liberalism. There is no room for whataboutism, because liberalism is not about showing how "they" are more evil than "us", because there is no "us" and "them".
