According to Eliezer Schweid, shlilat ha'galut, or the rejection of life in the Diaspora, is a central assumption in all currents of Zionism. The concept encourages the dedication to Zionism's enterprise and it is used to justify the denial of the feasibility of Jewish emancipation in the Diaspora. Life in the Diaspora would either lead to discrimination and persecution or to national decadence and assimilation. A more moderate formulation says that the Jews as a people have no future without a "spiritual center" in the Land of Israel.
