(JTA) — During Tucker Carlson’s interview last week with Mike Huckabee, the U.S. ambassador to Israel, both men made considerable waves with their takes on history and theology.

Huckabee sparked a diplomatic row by citing the Bible to argue that Israel had a divine right to claim all of the Middle East — even though he didn’t back doing so politically.

But Carlson’s own interpretation of Israeli sovereignty was also notable, as the far-right pundit insisted that Israelis should undergo genetic testing to determine if they have a rightful claim to the land.

“Why don’t we do genetic testing on everybody in the land and find out who Abram’s descendants are?” Carlson asked Huckabee at one point, using the name Abraham used before he made a covenant with God to become the first Jew. “It’s really simple. We’ve cracked the human genome. We can do that. Why don’t we do that?”

At another point, Carlson singled out Prime Minister Benjamin Netanyahu specifically as an illegitimate Israeli.

“What you’re saying is that certain people have a title to a highly contested region. They own it, in some deep sense,” he told Huckabee. “So I think it’s fair to ask, who are they, and how do we know? So the current prime minister’s ancestors weren’t from here within recorded history. He has no deed. Bibi Netanyahu, on one side, his family’s from Poland, they’re from Eastern Europe. So how do we know he has a connection to the people who God promised the land to?”

The line of questioning made little sense to many Jewish listeners, who understand Judaism as a blend of religion, ethnicity and community in which converts have always been accepted. For Jewish listeners, too, the idea of tracing bloodlines is often associated with the Nazis, who chose their victims based on how many Jewish ancestors they had.

But both Carlson’s critics, and supporters across the ideological spectrum who have agreed with his views on Israel, understood what he was getting at. They identified his line of questioning as a variation on the “Khazar theory”: the belief that Ashkenazi Jews, like Netanyahu, are genetically descended from a Turkic minority that converted to Judaism in the Middle Ages rather than from the 12 tribes of Israel. 

“The people currently occupying Israel are Khazarian Turks,” far-right pundit Candace Owens, a promoter of many antisemitic conspiracy theories, wrote on X.

“He has ZERO ancestral connection to the land. He’s Polish,” the far-left influencer Shaun King wrote on X about Netanyahu in praise of Carlson’s interview. “His real last name is Mileikowsky.”

The theories as to why the Khazars, who were a real people, would have converted en masse to Judaism have varied according to the teller; one tale holds that a Khazar royal held a debate between representatives of Judaism, Islam and Christianity to hold the best religion, and Judaism won out. But no matter how it happened, the theory goes, Jews who trace their genetics to Eastern Europe should not be considered rightful heirs of Israel, and should instead claim the Caucasus as their ancestral home.

The Khazar theory has a long history but was largely discredited with the advent of DNA analysis. Yet it has grown in prominence among antisemitic circles since the Oct. 7, 2023, Hamas attacks in Israel and ensuing Gaza war, according to research by the Anti-Defamation League. 

“Antisemites suggest that if Jews are descended from people not native to Israel (i.e., Khazars), then they have no legitimate claim to the land,” the ADL’s own description of the theory’s popularity notes. “In addition, because Nazis sought to expel Jews and others from their homes in Europe in order to obtain lebensraum (‘living space’) for ‘Aryan’ people, antisemites have argued that Jews are doing the same thing because they have no historic claim to the land of Israel.”

The ADL also notes that, setting aside the validity of the theory, most Israeli Jews are not Ashkenazi but rather trace their roots to North Africa and elsewhere in the Middle East.

The origins of the Khazar theory date back centuries and have always had some promulgation from Jews; Hungarian Jews in the 19th century latched onto the theory, according to researchers. The Khazar theory has also been promoted by some Jewish and Israeli scholars in more recent years, including Arthur Koestler in his 1976 book “The Thirteenth Tribe”; Shlomo Sand, a historian at Tel Aviv University who identifies as “post-Zionist,” in his controversial 2008 book “The Invention of the Jewish People”; and Israeli geneticist Eran Elhaik. 

This has further boosted the theory’s seeming validity among proponents: Owens, for example, has cited Sand’s book on X as evidence for the theory.

But such studies are largely refuted by established historical scholarship. “This claim, pardon my chutzpah, is nonsense,” Shaul Stampfer, an emeritus history professor at Hebrew University of Jerusalem, has said about the Khazar theory in college lectures.

In Stampfer’s own research into the Khazars, he said that while there were a few Jews among the Khazars, he has found no genetic links between the ancient Central Asian tribe and modern Ashkenazi Jews (whose own genetics have been thoroughly studied owing to a preponderance of genetic diseases in the population). There are, however, genetic links between Ashkenazi Jews and ancient Palestine, as well as to North Africa, he says. 

In addition, there are very few Turkic origins to be found in Yiddish, while there are extensive Latin origins in Yiddish, further boosting evidence of broader Jewish migration to Europe and decreasing the likelihood of mass migration from Turkey.

There are other practical considerations, too, Stampfer told the Jewish Telegraphic Agency this week.

“Take a look at a map,” he wrote in an email. “Even if the Khazars had converted, they would not have dragged themselves to Poland. It is far away and cold in the winter.”

The National Institutes of Health, too, published an extensive genetic study in 2013 that found “no evidence from genome-wide data of a Khazar origin for the Ashkenazi Jews.” 

The researchers assembled what they called “the largest data set available to date for assessment of Ashkenazi Jewish genetic origins,” as well as available genome sets from the Caucasus. Their conclusion, the abstract notes, “corroborates the earlier results that Ashkenazi Jews derive their ancestry primarily from populations of the Middle East and Europe, that they possess considerable shared ancestry with other Jewish populations.”

None of the evidence has stopped the Khazar theory from emerging as a lodestar of modern antisemitism, thanks in part to influential right-wing personalities such as Carlson. This is not the first time he has toyed with the idea of genetics testing for Jews, though he previously seemed to be aware that such an ask would carry undesirable connotations. 

“In order to determine who’s actually inherited the land, we would have to conduct global genetic testing to award property on the basis of the results,” he texted right-wing filmmaker Dinesh D’Souza months ago, according to D’Souza, who shared the text on a recent podcast. Carlson continued, “Sounds like a Nazi project to me. As a Christian, I reject that.”

“I don’t think that’s necessary any more than it’s necessary to genetically test Indians to make sure their ancestors are from India,” D’Souza, who is Indian-American, responded. “Remember Jews maintained their tribal identity. Very little intermarriage. They didn’t try to convert people, as Christians did.”

D’Souza continued, “Shakespeare’s ‘Merchant of Venice’ conveys the picture very vividly. The Jews don’t mix. So their continuity as a group is generally more secure than virtually any other group.” (“The Merchant of Venice,” which features the Jewish villain Shylock, is generally seen as promoting antisemitic stereotypes.)

Carlson responded by returning to the genetics question — and this time seeming more open to it than when he first called it a Nazi project. “I agree with all that and I admire it. I’m hardly against Jews,” he texted D’Souza. “But if the claim is that Jews have a genetic right to certain pieces of land, it’s going to be necessary to do genetic testing.”

The broader lurch into conspiratorial thinking on the right, exemplified by the views on the Jews and Israel espoused by Carlson, increasingly has some other conservatives worried about losing control of the narrative.

“The most popular digital content on the Right is now ‘Erika Kirk killed Charlie,’ ‘Epstein was leading a pedophile blackmail ring for the CIA’ and ‘Jews are a diabolical power destroying the world,’” Christopher Rufo, an influential right-wing thought leader who helped orchestrate the larger push against diversity initiatives, warned on X. “In these instances, we need to correct public opinion, rather than cave to it.”

For his part after the Carlson interview, Huckabee accused his interrogator of drawing on a “dangerous conspiracy theory” from “some of the darkest realms of the Internet” for his genetic testing line of questioning.

“I do know that the discredited idea that most Ashkenazi or European Jews descended from the ancient Turkic kingdom of Khazaria is bunk,” Huckabee wrote on X. “It’s also been weaponized by people trying to deligitimize [sic] Jews, to strip them of their history, and to call them ‘imposters’ or ‘fake Jews.’”

Stampfer was hesitant to diagnose why the Khazar theory may be growing in popularity today. 

“People who don’t like Jews might be attracted to the idea that this is one more Jewish lie,” he offered. Yet, he added, “Explaining why people believe what they believe is a tough business.”
