Dana Goldstein sees a big shift:
Polling of young American Jews shows that with the exception of the Orthodox, many of us feel less attached to Israel than do our baby boomer parents, who came of age during the era of the 1967 and 1973 wars, when Israel was less of an aggressor and more a victim. A 2007 poll by Steven Cohen of Hebrew Union College and Ari Kelman of the University of California at Davis found that although the majority of American Jews of all ages continue to identify as "pro-Israel," those under 35 are less likely to identify as "Zionist." Over 40% of American Jews under 35 believe that "Israel occupies land belonging to someone else," and over 30% report sometimes feeling "ashamed" of Israel's actions.
She follows up at her blog:
What I didn't have space to explain in the piece is that even organizations that have traditionally promoted an uncritical view of Israel are now accepting that the terms of the debate have changed. Hillel, for example, the most prominent Jewish organization on college campuses, last week launched "Talk Israel Tents" on 21 campuses, in which students were encouraged to openly debate Palestinian statehood and other issues.
