In 1984, Israel’s then-President Chaim Herzog refused to meet with the newly seated parliamentarian Rabbi Meir Kahane, the leader of the now-outlawed Kakh party, despite meeting with the heads of every other party in the Knesset. The refusal no doubt owed to Kahane’s anti-Arab bigotry and sympathy for vigilante violence. Discovered in Herzog’s archives was what appeared to be a letter from the revered American rabbi Joseph B. Soloveitchik upbraiding him for his frostiness toward Kahane and stating that the latter was “despite his many, many errors, a God-fearing Jew who fights for the honor of Heaven and of the Jewish people.”

Mosheh Lichtenstein cites extensive textual evidence to argue that the letter is a forgery. Not only does it use numerous uncharacteristic turns of phrase, but the signature does not match Soloveitchik’s—either in the handwriting script or in the spelling of his own name. Lichtenstein adds:

I am not judging the letter based upon any presumed attitude of Rabbi Soloveitchik regarding Rabbi Kahane. However, the content of the letter is extremely problematic for . . . other reasons. [The] letter concludes with a clear admonition and rebuke to President Herzog in no uncertain terms regarding his own [lack of religious] observance. Not only does the writer allow himself to criticize Herzog’s standards of public observance, an obviously sensitive topic for someone raised as an observant Jew, he also doesn’t shy away from introducing the extremely sensitive and intensely personal issue of Herzog’s relationships with his parents and [his own] children.

The Soloveitchik that I knew . . . would never enter into such personal matters and grant unsolicited advice or pass judgment upon his correspondent’s personal life and relationships. For that matter, I cannot imagine that any rational individual who is requesting a favor from a person of stature would conclude his message by rebuking the person and making it clear that he is a disappointment to his parents. . . . Soloveitchik would not, and could not, have written such a text.

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.
