Being a privileged member of the majority in the most powerful country the world has ever known is a fairly unique experience for Jews. Israel, though hated and vulenrable to terrorist threat, is nevertheless the dominant military power in the Middle East. A history defined by agonizing persecution has given way to a present defined by relative power. But that has, inevitably, changed the relationship young Jews have to both Judaism and Israel. And that's created substantial concern among older Jews, who sense that the younger generation's connection to Israel is either slipping or, at the least, becoming something less visceral and recognizable. Just ask my grandfather. J Street -- which has always sold itself as a net-oriented enterprise for the Obama generation -- inflames that anxiety. My hunch is an examination of AIPAC's demographics -- and even more so its active membership -- wouldn't bar the organization from membership in AARP.I'm not even sure this is a uniquely Jewish experience. I think it's fair to say that gentiles of my generation are significantly more critical of Israeli policy than our parents and grandparents, for similar experiential reasons. The Israel my parents grew up with faced Nasser's coalition, the slaughter in Munich, and a violent nationalist movement aligned with the Soviet Union. The Israel I grew up with bulldozes Palestinian homes, is unthreatened by any neighbors, and has repeatedly disrespected a moderate movement that had offered it significant concessions. It's easy for someone with the former experience to view Israel as an ally in need of American protection, separate from any personal connection to its mission as a Jewish state. Similarly, it's easy for someone born in the '80s or '90s to view Israel as an incredibly powerful nation that not only doesn't need America's help, but could afford to be pushed into a more sensible course of action by Washington. These aren't identity shifts so much as pragmatic ones, but they result in the same trends Ezra outlines within the Jewish community.
