While Germany and many other countries have made progress in restoring goods seized during World War II to their rightful owners, the Netherlands still holds a mass of paintings that once belonged to Jews, as Avraham Roet writes. (Free registration required.)

Much of the art confiscated from Jews during the German occupation can still be found in warehouses belonging to the Dutch state, or in museums around the country. Because Dutch authorities have been remiss in preserving archives and documentation, however, it’s not possible to make an accurate appraisal of the value of the plundered art. . . .

Though the war ended more than seven decades ago, the scale of the thefts from Jews by both the Germans and Dutch people themselves—not only during World War II but afterward as well—is still coming to light. Following the German conquest of the Netherlands, on May 10, 1940, Adolf Hitler and his deputy Hermann Goering began taking an intense personal interest in the acquisition of art, in particular paintings by Old Masters. Hitler intended to establish—in Linz, Austria, near the village where he was born—the world’s largest museum of classical art and objects. To that end, he ordered the confiscation of art in every country occupied by the Third Reich. At the same time, Goering began stealing obsessively for his own private collection, often competing with Hitler for the same items. . . .

The Allies, aware of the art-looting phenomenon, decided, as early as 1942-1943, that all plundered property would be returned after the war to its country of origin, without compensation being made to the then-current owner. . . . In 1945, the Netherlands government set up the Netherlands Art Property Foundation (SNK). . . . Anyone who knew of artworks owned by his or her family that had been stolen could fill out an SNK form requesting their return. Tens of thousands of requests poured in. . . . A substantial number of SNK applicants indeed took their property back, but that still left tens of thousands of items in the hands of Dutch state authorities after their repatriation from Germany.

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.
