Iran’s leadership has returned to Holocaust denial, its leader made clear in an interview with “60 Minutes,” after distancing itself from the phenomenon

“Historical events should be investigated by researchers and historians,” Ebrahim Raisi, the Iranian president, said in an interview on the CBS News flagship broadcast Sunday when he asked if he believed the Holocaust occurred. “There are some signs that it happened. If so, they should allow it to be investigated and researched”

The interview aired at the same time that PBS was showing the first installment of a six-hour new documentary, by Ken Burns, about the Holocaust. “The U.S. and the Holocaust” is the latest prominent work to make use of the vast trove of research available to scholars and laymen to show in meticulous detail evidence of the Nazi genocide of European Jewry

The falsehood that research that would deny the Holocaust is being repressed is a commonplace trope among Holocaust deniers[…]
Responding to a tweet quoting Raisi, Israeli interim prime minister Yair Lapid offered just two words — “Some signs” alongside four black-and-white photographs showing starved and murdered Holocaust victims. He was one of many people to lampoon the Iranian president’s comments on social media.
