The Jewish Research Institute (YIVO), founded in 1925 in the Polish city known to Jews as Vilna (now Vilnius, Lithuania), contained the world’s largest archive of East European Jewry before World War II. Parts of the collection survived the Holocaust through a series of bizarre twists involving the Nazi institute for “the study of the Jewish question” and the U.S. Army, and most of the materials eventually made their way to YIVO’s new headquarters in New York City. But others remained behind the Iron Curtain—until now, when at last the two collections will be reunited via the Internet.

“These materials are Holocaust survivors,” said David E. Fishman, a professor of Jewish history at the Jewish Theological Seminary who is working on a chronicle of the YIVO collection’s rescue. “Like a survivor, these materials were controlled by the Germans. Like a survivor, they were in hiding. The fact that they were saved is miraculous.”

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.
