My take is this- Zionism's fundamental error of judgment was and remains the "The Jewish State". Rather than creating a new liberated and independent state for both the Jewish and Arab residents it focused on an independent state in which the Jewish population would dominate, call the shots, and benefit over and above everyone else. This immediately set Jewish and Palestinian interests apart and laid the groundwork for segregation and discrimination to come and dominate the scene, along with all the demographic hanky-panky. It is likely possible that had the Zionist ideology not been so innately hostile and secessionary vis-a-vis the Arab population, being all about Herzl's "rampart" against Asia, "The Jewish State"; had it been more universalist, individualistic, less tribalistic, more idealistic, open and free, what Israel professes to, but which it is not, then the State of Israel could have come about sooner and its doors open as refuge to all. Zionism is the divider.
