Traces the dialectical connections between Zionism's past and present. In Zionism, the late Nathan Rotenstreich traces the dialectical connections between Zionism's past and present based on his contention that the Jewish nation comprises both the State of Israel and the Diaspora. He also addresses relations between both Israel and the Diaspora, on the one hand, and Israel and the Arab world, on the other. Written a short time before Rotenstreich's death, Zionism can be regarded as his spiritual and ideological legacy.
