In his quest to discover the sources of the growing rift between American Jewry and Israel, Daniel Gordis convincingly argues that, rather than being traceable to the character of Israeli policy vis-à-vis the Palestinians, or to changing patterns in American Jewish life, the rift is over issues of “moral and political essence and ideology”—issues of, in a word, identity. He proceeds to diagnose four divergent “political and cultural assumptions” that, taken together, expose the ways in which Israel and America represent “two fundamentally different if not antithetical political projects.” Although the resultant tensions between Israeli and American Jews are “as old as Israel itself,” rarely if ever have they generated the fissures currently dividing the two communities. The question, then, is: why now?
