I don’t think that’s giving American Jews enough credit.
Israel as a bug-out plan for anyone with Jewish heritage is a distinctly Zionist idea, which is far more polarizing these days.
But even if some Jews may be given to such a demonstrably facile us-them disposition — i.e., security-at-all-costs with no sense of irony whatsoever — my impression is that many find it impossible to ignore the apparent gollum of this increasingly explicit mechanized hegemonic genocidal fascist apartheid state somehow laying claim to their worldwide identity.
If I were an American Jew, I would be asking myself “is this what being Jewish means to me?” And I suspect my answer would be outrage to the tune of “no, fuck Zionism” or “no, fuck Israel.” Either way it would consume me utterly.
In short, I just find it hard to believe the average Jew is especially ignorant, heartless, or selfish. That to me sounds like actual antisemitism.
ETA: I can’t speak for American Jews but most of the Jews I know are either older and just anti-bibi or younger and openly anti-Zionist. This is in New York for context.
