Sixty years after Israel's establishment, Zionism stands as an unfinished project demanding renewal rather than abandonment. By examining the writings of pivotal Zionist thinkers like Herzl, Halevi, and Kook alongside modern Israeli religious and political movements, a clear pattern emerges: authentic Zionism encompasses both political sovereignty and spiritual-moral transformation. Theological and historical analysis reveals that while Orthodox approaches to Zionism have grown ahistorical and politically stagnant, the Masorti (Conservative) movement represents an untapped radical religious force capable of advancing Zionist ideals. To harness this potential, a three-part program for Masorti political engagement is proposed: establishing ideological frameworks for renewed religious Zionism, building multi-denominational coalitions for institutional reform, and developing strategic partnerships with Sephardic Judaism. The research demonstrates that fulfilling authentic Zionist aspirations requires active political participation by moderate religious movements to restore the "lost heritage" of Jewish sovereignty. These findings contribute to contemporary debates about religion-state relations in Israel and the role of religious movements in democratic politics, ultimately advocating for a multi-denominational approach to political engagement that transcends narrow sectarian interests.
