There always have been questions on over representation in every single influential position, which was explained by the Ashkenazi Jews who developed reputation to be statistically gifted or the culture that was shaped to seek such professions and positions due to prosecution.

But the straight up committing genocide, then US supporting that despite losing all kind of public support and the support of the allies and then Israel attacking the US allies without consequence to them is what will bring thing together and will make antisemitism mainstream and popular.

Kicking people out, limiting accounts, cutting off finance and services, cancelling people, smearing people won't cut it because this thing is brewing into a perfect storm. Anyone who cares about the Jewish people should make it stop and then make it right. Or maybe this by design to "convince" Jewish minority to move to Israel so that the Israeli political class becomes more powerful?
