The city of Shanghai recently applied to have its former Jewish quarter added to the UNESCO Memory of the World Register. During World War II, the city, by then under Japanese occupation, became home to some 20,000 European Jewish refugees. In 1943, Japan succumbed to German pressure and forced the Jews into a ghetto. Although they suffered from disease, poor sanitary conditions, and lack of food, Shanghai’s Jews were far better off than their brethren in European ghettos. Gabe Friedman and Julie Wiener revisit their history:

[T]he first German Jewish refugees, many of them doctors and dentists, arrived soon after Hitler’s rise to power. The local community was apparently so grateful for the professional skills these refugees brought that the Jewish Telegraphic Agency headlined a 1934 article “German Jewish doctors cause China to be grateful to the Nazis.” . . . [A]n American journalist working in China said approximately 100 Jewish doctors had set up practices in Shanghai. . . .

In 1937, Japan’s occupation of China brought both good and bad news for Jews there. On the bad side, the conquest of Shanghai was preceded by months of fighting, and during that period . . . Shanghai rabbis reported the situation of the Jews was “desperate.” . . . On the plus side, under Japanese occupation, Shanghai became an “open city,” providing a haven for thousands of Jews with nowhere else to go.

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.
