The history of Zionism illustrates a dynamic within the Jewish community in which the most radical elements end up pulling the entire community in their direction. Zionism began among the most ethnocentric Eastern European Jews and had explicitly racialist and nationalist overtones. However, Zionism was viewed as dangerous among the wider Jewish community, especially the partially assimilated Jews in Western countries, because it opened Jews up to charges of disloyalty and because the Zionists' open racialism and ethnocentric nationalism conflicted with the assimilationist strategy then dominant among Western Jews. Zionist activists eventually succeeded in making Zionism a mainstream Jewish movement, due in large part to the sheer force of numbers of the Eastern European vanguard. Over time, the more militant, expansionist Zionists (the Jabotinskyists, the Likud Party, fundamentalists, and West Bank settlers) have won the day and have continued to push for territorial expansion within Israel. This has led to conflicts with Palestinians and a widespread belief among Jews that Israel itself is threatened. The result has been a heightened group consciousness among Jews and ultimately support for Zionist extremism among the entire organized American Jewish community.
