Monday is the fifteenth day of the Hebrew month of Shvat, called by the Talmud the “new year of the trees” as it marked the beginning of a new period for the tithing of fruits. Over the centuries it developed into a holiday, known in Hebrew as Tu b’Shvat—first transformed by 16th-century mystics, then by early Zionists, and finally by the Jewish Renewal movement into a sort of Jewish Earth Day. This last transformation, argues Meir Soloveichik, with its overtones of rootlessness and ideological malleability, betrays the day’s longstanding significance as a celebration of the enduring connection with the Land of Israel, and hope for return to Zion.

Two extraordinary events demonstrate something important about Israel’s most fervent adversaries. One was a speech given at something called The People’s Forum (funded generously by Goldman Sachs), which stated, “When the state of Israel is finally destroyed and erased from history, that will be the single most important blow we can give to destroying capitalism and imperialism.”

The suggestion that this tiny state is the linchpin of a global, centuries-old phenomenon like capitalism goes well beyond anything resembling rational criticism. Even if Israel were guilty of genocide, apartheid, and oppression—which of course it is not—it would not follow that its destruction would help end capitalism or imperialism.

The other was an anti-Israel protest that took place in front of New York City’s Memorial Sloan Kettering Cancer Center, deemed “complicit” in Israel’s evils. At organizers’ urging, participants shouted their slogans at kids in the cancer ward, who were watching from the windows. Given Hamas’s indifference toward the lives of Gazan children, such callousness toward non-Palestinian children from Hamas’s Western allies shouldn’t be surprising. The protest—like the abovementioned speech—deliberately conveyed the message that Israel is the ultimate evil and its destruction the ultimate good, cancer patients be damned.

The fact that Israel’s adversaries are almost comically perverse does not mean that they can be dismissed. If its allies fail to understand the obsessive and irrational hatred that it faces, they cannot effectively help it defend itself.
