Last week, two Israeli hikers came across an ancient coin, apparently exposed by recent winter rains. Realizing its likely historical value, they handed it over to the archaeologist Zvika Tzuk, who in turn showed it to his colleague Danny Syon. Tzuk and Syon identified the coin as one minted by followers of the Jewish rebel Shimon Bar Kokhba during the brief period when they managed to liberate parts of Palestine from Roman rule. Michael Bachner writes:

Despite the fact that the coin hadn’t yet undergone professional cleaning yet, Syon succeeded in deciphering the images and inscriptions on the rare coin, determining that it dates back to 133 or 134 CE.

One side of the coin had an image of a palm tree with seven branches and two clusters of grapes above the name “Shimon”—Bar Kokhba’s first name—in ancient Hebrew. The reverse side of the coin had a vine leaf with a twig and around it an inscription meaning “the second year of the freedom of Israel.” Coins of this type were minted during the Bar Kokhba revolt from 132 to 135 CE, during which time Jewish rebels managed to regain some autonomy from Rome. The “second year” is either the year 133 or the year 134 CE. . . .

“The road near where the coin was found connects a number of communities with hiding places from the days of Bar Kokhba,” said Tzuk. “It is possible that one of the residents or fighters who moved from one community to another lost the coin, which waited 1,885 years until it was found.”

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.
