How do you tell the difference between a Jewish pessimist and a Jewish optimist?

Easy. The pessimist says, “Things just can’t get any worse. The optimist says, “Sure they can.”

Well, they certainly have — as far as the fraught connection between Israel and liberal American Jews goes.

The latest stressor is a predictably nasty media exchange over high-profile liberal commentator Peter Beinart’s recent declaration that he no longer backs a two-state solution to the Israeli-Palestinian conflict.

A single bi-national, or perhaps a confederated, state, said Beinart, is the best remaining equitable option. This, he concluded, is because of Israel’s deeply entrenched West Bank settlement project. Further undermining the two-state option, he said, is Prime Minister Benjamin Netanyahu’s threat to annex much of the occupied West Bank that Palestinians want to include in their own independent state.

Beinart detailed his thoughts in this New York Times oped and, in much greater detail, in this Jewish Currents essay.

For liberal Jews — who have long argued that two independent states coexisting side by side, one Jewish-run and one Palestinian, is the best and only realistic option — Beinart’s abandonment of full Jewish nationhood was nothing less than Zionist heresy.

Naturally, given today’s insatiable 24/7 media universe — in which all who dare venture are but a tweet away from “woke” fame or “cancel culture” renunciation — the verbal warfare started immediately.

Beinart’s, you may be wondering, is but one voice in a cacophony of voices claiming to know what’s best for Israel-Palestine, so why the fuss? Moreover, he lives in the United States, not Israel, so to what degree does his opinion even matter?

The answer, of course, is his American media prominence. His frequent talking-head appearances, (he’s a CNN regular) and voluminous writings have won him a place in the liberal Zionist media firmament, where he’s long been a harsh critic of Netanyahu and Israel’s treatment of Palestinians. That’s not Hollywood famous, but it’s a start.
