On November 3—just one week after the massacre at the Tree of Life synagogue in Pittsburgh—John Podhoretz’s younger daughter celebrated her bat mitzvah. He addressed the following reflections to her on the occasion:

The haftarah you read today, from the book of Kings, is about a struggle over King David’s inheritance. It concludes with [his wife] Bathsheba speaking the words “May my Lord King David live forever.” What Bathsheba meant was that David’s line should live forever, that the Jewish people should live forever. After the unspeakable event . . . at Pittsburgh’s Tree of Life Synagogue, it is an obligation upon you and upon us to do what we can, every one of us, to make sure Bathsheba’s wish is fulfilled.

The theologian Emil Fackenheim said Auschwitz had required this of us—that we were not allowed to grant Hitler any posthumous victories. He called it the Commandment of Auschwitz. It is also the Commandment of the Tree of Life. The monster who slaughtered and wounded all those people wanted to kill Jews for being Jews. “All Jews must die,” he shouted as he murdered them.

The parashah from the Torah you read today is about the very first Jews. It begins with the death of Sarah and proceeds to tell of the death of her husband, Abraham. So here is my charge to you: if you want to make [the Pittsburg shooter’s] words turn to ash, follow in the footsteps of Abraham and Sarah. Live as a Jew. Have Jewish children. Try as your mother and I have with you and your sister and your brother to teach those children how to live as Jews so that they can teach their children, and their children can teach theirs, and theirs and theirs and theirs and theirs—until it is 3,600 years from now and there are still Jews on this earth just as there were 3,600 years ago when Abraham and Sarah breathed their last.

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.
