How do you think the genocide in Palestine (caused by the country of Israel) would stop? Would there be a revolution? Is the genocide because of imperialism running rampant? Does socialism has the tools necessary to stop this genocide (among other things)?
“Zionist elites” is a dog whistle, because it resounds of conspiracy theories about insidious control by Jews, as distinct from plainly visible political processes. The phrasing is actively used to propagate such counterfactual and dangerous beliefs. Because it has such history, the phrase is not functioning simply toward a neutral explanation of established facts.
The essential observations are that Zionism is fundamentally a European project, and that Israel is fundamentally a US colony. Even if some politicians fail to follow the plot on every detail, the existence of Israel as a settler-colonial ethnostate is plainly aligned to state interests. The US supported the creation of Israel, and the relations of colonial vassalage would remain even if the lobbying were dismantled.
The only means of altering the relationship is to attack the heart of the US political establishment and the military-industrial complex.
