A growing ideological schism threatens to separate Israeli "Hebrews" from diaspora "Jews," driven by three interlinked cultural phenomena in contemporary Israel. Through ethnographic observation and textual analysis of ideological statements, personal correspondence, and educational curricula, deep divisions emerge in how Jewish identity is conceived and transmitted. The defunct Semitic Action movement's rejection of diaspora Judaism continues to shape Israeli youth attitudes toward world Jewry, while stark contrasts between Israeli and American Jewish education - revealed through comparative case studies of two children - point to divergent paths of cultural transmission. Israeli education's heavy emphasis on biblical history creates a problematic two-millennium gap in historical consciousness, effectively minimizing the diaspora Jewish experience. This combination of "Canaanite" ideology among youth, disparate educational approaches, and selective historical narrative risks producing an Israeli generation increasingly disconnected from the broader Jewish historical experience. Without addressing these educational and cultural gaps, both Israeli Jewish identity and diaspora-Israel relationships face mounting challenges to their continuity and coherence.
