When the 1967 New Politics Convention in Chicago passed an anti-Israel resolution amid chants of "Black Power," it marked a pivotal moment exposing deeper patterns of populist antagonism toward Jewish communities in America. Through historical comparative analysis, striking parallels emerge between this convention - dominated by SNCC and Black Power elements - and earlier Populist and Progressive movements of the late 19th and early 20th centuries. The same hallmarks appear across eras: conspiracy theories, anti-Semitic undertones, and moral absolutism. These patterns take on renewed significance as contemporary neo-populist rhetoric increasingly echoes the isolationist movements of the 1930s that opposed American intervention against Nazi Germany. Today's American Jews face potential threats from both left and right-wing populism, complicated by modern factors like Israel's military capabilities, urban tensions, and international criticism - challenges more complex than those of previous generations. The research methodology reveals that Jewish educational institutions have largely failed to equip younger generations with the historical context needed to recognize and understand these recurring patterns of populist scapegoating during periods of social upheaval.
