Not only is there the issue of inner purpose and drive of the communal life of a nation, but also of the ethics of nationalism, relations between nations. Dubnow writes: "There is absolutely no doubt that Jewish nationalism in its very essence has nothing in common with any tendency toward violence." Because of the diaspora experience, "as a Jew, I utter the word 'national' with pride and conviction, because I know my people... is not able to aspire anywhere to primacy and dominance. My nationalism can be only a pure form..." The prophets "called Israel a 'light to the nations' taught the spiritual mission of the people of Israel... to bring other peoples, that is, all 'mankind,' to spiritual perfection." Thus, the nation inspired by Judaism, "the descendants of the Prophets," will promote and inspire the social ethics of humanity, and will come to harmonize with its realization: "the equal worth of all nations in the family of mankind." The "Jewish national idea, which can never become aggressive and warlike" will raise aloft its flag, which symbolizes the joining of the prophetic vision of "truth and justice with the noble dream of the unity of mankind."
