That would be horrible because Jews are mostly white and Palestinians aren't. Clearly your hypothetical Holocaust is worth committing an actural Holocaust to "prevent". Have you considered that (as a Jew) the Israeli government and military is actively bad for Jewish ppl. They're actively censoring Jewish voices who disagree with them (Bibi is trying to shut down Haaretz). Therefore as a Jew I do not believe that Jewish and Muslim workers should fight but rather all the workers should unite against the capitalist classes that truly oppress them.
