The old trope I’m referring to is the
Judeo-Masonic conspiracy theory[1], is a belief in a global conspiracy of Jews influencing the world order. Modern variation of this trope are right wing conspiracy theories such as
Cultural Marxism[2] or the
White Replacement Theory[3] (I know, right wing conspiracy theories are not super consistent in ideology).
What I thought you were referring to (and I may be wrong) was the conspiracy theory of the Jewish Lobby[4], or the more innocent—i.e. non-antisemitic variation (and not a conspiracy theory)—the Israel lobby.
While the Israel lobby exists (not to be confused with the Jewish lobby, which doesn’t; or at least not in a way which massively influences US policy), and is probably has some influence at the US government. And while Israel funded astro-turf campaigns also exist, and are probably paying (or otherwise influencing) agent provocateurs[5] at the student protests, to suggest that those are all linked and to hint this is the reason for US government policy, that is getting kind of close to the Cultural Marxism conspiracy theory.
I certainly hope that I’m actually the one that is reading too much into this, and this is not actually what you meant. If so, then I apologize for making these accusations.
