The publication of some of Martin Heidegger’s “black notebooks”—unpublished writings from the Nazi era—have shown the extent of the support for Hitler given by the prominent German philosopher and the centrality of anti-Semitism to his worldview. A forthcoming volume of the notebooks contains extensive writing on the Holocaust, refuting the once widely-held assumption of his “silence” on the subject. It turns out he was certain the Jews brought it on themselves, as Donatella Di Cesare writes:

[I]t is no surprise that Heidegger should discuss the Shoah and consider it from both philosophical and political viewpoints. Selbstvernichtung—self-destruction—is the key word. [Heidegger’s] argument is that the Jews destroyed themselves, and no fingers should be pointed at anyone except the Jews themselves. . . .

Heidegger does no more than draw his conclusion from everything he has said previously. The Jews are the agents of modernity and have disseminated modernity’s evils. They have besmirched the spirit of the West, undermining it from within. Accomplices of metaphysics, the Jews have everywhere brought about the acceleration of technology. The charge could hardly be more serious. Only Germany, with her people’s iron cohesion, could stem the devastating impact of technology. This is why the global conflict was primarily a war of Germans against Jews. If the Jews were annihilated in the death camps, it was because of the mechanism that they fomented by plotting to achieve world domination. The link between technology and the Shoah should not be disregarded: it was Heidegger himself who alluded to it elsewhere. What is Auschwitz if not the industrialization of death, the “fabrication of corpses”?

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.
