Craig Mokhiber, who has been serving as director of the New York office of the United Nations High Commissioner for Human Rights, sent on Saturday what he called “my last official communication” to the high commissioner, Volker Türk. The letter, now publicized, represents likely the most polemical and bigoted screed by a senior U.N. official on the body’s only Jewish member state, and on supporters of Israel’s basic legitimacy and security, in recent history. It also confirms widespread indifference—”among most of our staff,” in Mokhiber’s words—to the equal rights and very lives of Jews, after Palestinian terrorists perpetrated this month the most horrific atrocities among Jewish civilians since the Holocaust.

B’nai B’rith demands that U.N. leaders, including Secretary-General Guterres and High Commissioner Türk, directly and publicly repudiate the sentiments in Mokhiber’s letter as antithetical to the United Nations and its foundational values.

In his letter, Mokhiber—a longtime voice of overt, shrill ideological prejudice despite his important position in the U.N. human rights apparatus—censured the world body for failing to stop what he repeatedly called Israeli “genocide” against Palestinians.

The U.N. already condemns Israel, the Middle East’s only democracy, more than all other countries combined, and extreme activists’ longstanding libel of “genocide” by Israel is contradicted in the clearest possible way by facts on the ground. Hamas and other Iran-sponsored fanatics are, by contrast, explicit in their crude anti-Semitic worldview—and their genocidal aspirations and actions.

Mokhiber mentioned none of this in his four-page letter, not even Hamas’ unspeakable crimes against humanity this month.

“Good riddance, Craig Mokhiber,” B’nai B’rith International President Seth J. Riklin and CEO Daniel S. Mariaschin said. “Nonetheless, what a tragedy and an outrage that he could not leave his post without grandstanding and without publicly advertising his disregard for the lives of Israelis and Jews.”

In his letter, Mokhiber wrote of “genocide,” “ethno-nationalist colonial ideology,” “settler pogroms,” “Israeli Apartheid,” the “Israel Lobby” and a need to constrain its representatives’ access to the U.N. He outrageously claimed the impending “destruction of the last remnants of Indigenous Palestinian life,” and also advocated a one-state solution to the conflict.

Mariaschin asked, “What planet does Mokhiber live on? Of course, Jews do not represent a ‘settler colonial project’ in Israel. There is no denying thousands of years of Jewish historical presence in the land. Mokhiber has also been completely blind to the repeated efforts by Israelis to bring peace, over decades, to the region.”

“There is no wild, fabricated smear that Craig Mokhiber will not direct at Israel, and no violation of Israelis’ human rights that he will be bothered by,” B’nai B’rith Director of U.N. and Intercommunal Affairs David Michaels said. “Craig Mokhiber is a walking illustration of clueless, shameless anti-Semitism, despite his attempt to assume the right to preempt and belittle that charge. His blindness to all facts that he prefers not to acknowledge is nonetheless shocking coming from a senior U.N. official and a supposed defender of human rights. Israeli Jews are humans too.”

Mokhiber’s parting screed should be denounced for the one-sided extremism it represents and U.N. officials should invite employees with similar “views” to join him in departing an organization in which Jews and the State of Israel, are meant to be treated equally and with dignity.
