Zionism, as a political movement, was the catalyst behind the creation of the state of Israel. Zionism now must help insure the survival of that state. The land of Israel and the Jews' return to that land sustained Zionism, shaping its political agenda and its subsequent implementation. The Israeli-Palestinian crisis over the right to the West Bank and Gaza has so dangerously deteriorated that it now could explode into a full-scale civil war. Israeli leaders currently are asking the same question that faced Zionist elders when the United Nations offered its partition plan in 1947: Should Israel settle for less than the biblical promise? Should the Jews forgo the grand design of Israel for the sake of peace? The Arab nations flatly rejected the partition plan, which provided for a Jewish and a Palestinian state, and invaded Israel in 1948. As a result of the war, Israel expanded its landholdings and maintained them until 1967.
