This article by Allison Benedikt has generated some heated debate in recent weeks and I think reflects a disturbing (from an Israeli POV) trend. Young American Jews, a generally liberal bunch, are finding it increasingly difficult to support Israel c. 2011 due to the intense moral clash this creates with their internal belief system. Fewer and fewer young American jews today are Zionists, and fewer and fewer American Zionists today are liberal. The liberal diaspora deserting the country would be a nightmare for Israel and would eventually lead to an othodox-dominated diaspora being their main public supporters... this is kind of already happening I think. Unfortunately I see no sign of this reversing in the future.
