As unfortunate as it is, genocides and persecution based on ethnicity or religious orientation are not unique to the Jewish experience. In either case the solution is to target these actions and these policies. The existence of the state of Israel does nothing to further action against these efforts, if what you allege about entire cities in Europe is indeed true. Israel seems to not protect the European Jew at all, nor the African Jew, the Asian Jew, or the Jew anywhere really aside from the Jew within the state of Israel who is actively working to further the goals of the armed forces of Israel, because the state of Israel itself turns its back on Jews in Israel who are critical of this direction.
I just can't get over the cognitive dissonance that this sort of primitive tribalistic propaganda world view creates. Where on the one hand it is claimed that these groups are like water is to oil: entirely immiscible and irreconcilable and should be kept apart as the sole solution. Then you go to a random city in the United States and Germans, Jews, Iranians, Chinese, Russians, and Americans are all neighbors, seeing themselves as equal, working together and raising their kids together, thinking nothing of it because they all share more or less the same exact lived experience.
