Today, because of the existence of an opportunity to end the exile, because of the existence of a choice, its very rejection by world Jewry endangers the future of Judaism. Assimilation is no longer the product of compulsion, of a lack of options; it is rather a voluntary process in which the existence of a choice serves as a catalyst. The results are evident: massive assimilation, intermarriage, lack of participation in communal organizations. A thirst for new life styles, ideologies and exotic religions as well as low birth rates, are ravaging world Jewry. In France and North America there are calls for the legitimation of the diaspora , echoing movements from the past that strove toward the elevation of Diasporic secular culture to an ideal. Since Jews have always defined themselves as a nation with a link to the land of Zion, these calls pose a danger to unity, to the ties that have held together the international Jewish community. Those who wish to endow life in the Diaspora today with a new aura of validity disregard traditional perceptions of collective Jewish existence.
