A very good thesis here by Peter Beinart on the growing ideological gulf between American Jews of different generations, and between Orthodox/Israeli Jews and liberal Jews.
The article is also about a much bigger and scarier issue, however: the slow asphyxiation of democratic values in Israel. Major government figures in Israel believe that Israeli Arabs should have their citizenship revoked. Not for committing acts of terrorism, mind you; for simply being Arab. Huge percentages of Israelis believe Arab citizens should be barred from serving in the Knesset. And the youngest generation of Israelis is the most right wing and authoritarian of all.
