The University of California, Los Angeles has invited BDS-supporter Cornel West to be the keynote speaker at an event in honor of Abraham Joshua Heschel. In an open letter to West, Judea Pearl, a professor of computer science at UCLA, urges him to decline the invitation:

No matter how eloquent your speech and how crafty your words, the audience you will face at UCLA will not be able to take them too seriously in light of your recent decision to become a leading propagandist for the Boycott, Divestment, and Sanctions (BDS) movement. You have to forgive us for being pedantic in these matters, and perhaps not as flexible and nuanced as one might hope, but our history has taught us the importance of devising crisp and visible litmus tests to distinguish friends from foes. It so happens, and you know it as well as we do, that the term BDS has become our most reliable litmus test. In other words, we have come to equate promoters of BDS ideology with those who seek the destruction of Israel, hence the demise of the Jewish people.

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.
