Albert Einstein spent much of the latter part of his career as a self-proclaimed public intellectual, advocating pacifism and (a qualified) Zionism and denouncing nuclear weapons and the cold war. Gertrude Himmelfarb, reviewing a new biography, examines his political evolution:

What [Einstein] discovered in Germany [in the 1930s] was a denigration of Jews, even among scientists and intellectuals, that gave him a heightened appreciation of his Jewishness—not as a religion, to be sure, but as a culture; even, he ventured to say, a nation: “Not until we dare to see ourselves as a nation, not until we respect ourselves, can we gain the respect of others.” But it was a special kind of nation he had in mind, defined by morality rather than polity. . . .

This was not quite the nationhood most Zionists had in mind. Einstein shared their idea of Palestine as a refuge for persecuted Jews—not, however, as a homeland reserved for them but as a safe area where they could live in peace with their neighbors. He also valued it as a center of Jewish learning and culture, to exemplify the “intellectual striving” that he saw as the essence of Judaism. . . .

[By the 1930s,] Einstein had come a long way from the physicist to the social activist. It is as if, displaced by quantum mechanics from the center of physics, he found a new calling in politics. But perhaps not entirely a new calling, for he was now seeking a rationality in society akin to the reason he had so passionately sought in physics. . . .

In retrospect, Himmelfarb concludes, “some of Einstein’s views, on war and peace, capitalism and socialism, Judaism and Zionism, may appear as almost a parody of the right-minded (which is to say, left-thinking) progressive of his time.”

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.
