Rabbi Yehuda Kaploun, the newly confirmed U.S. special envoy to monitor and combat antisemitism, was interrupted three times during a Thursday afternoon think tank event about his new role.

The first was a phone call from Harmeet Dhillon, the Justice Department’s assistant attorney general for civil rights, which he sent to voicemail. The next two were protesters who had somehow made it through security at the conservative Hudson Institute to loudly chant “free Palestine” in the midst of Kaploun’s remarks before being escorted out. 

Those unexpected interruptions framed Kaploun’s pitch as he settles into his new role at the State Department: First, that he will be successful because he is working on behalf of an administration that is committed to fighting antisemitism (“If you want to know how the administration works together, that was Harmeet Dhillon,” he said as he silenced his phone). And second, that education — and pushing back on false narratives about Israel and the Holocaust — is the most important way to combat antisemitism. 

“The hardest job that I have is how you effect a change in education across the board, by teaching people not to hate, and that’s the battle,” Kaploun said in a conversation moderated by Hudson senior fellow Michael Doran. 

Kaploun, a businessman and Chabad-trained rabbi, was confirmed by the Senate in December, must now build out a staff at the State Department and figure out how to make an impact diplomatically.

“The task is a daunting task, but we are blessed that this administration has really made antisemitism a priority, and how to combat and deal with antisemitism is something that the president and the secretary of state have made it perfectly clear that this is one of the priorities of the administration, is holding people accountable,” said Kaploun.

He said most countries in the world have a problem with antisemitism, and his message to leaders in those countries comes back to President Donald Trump: “You start with the concrete policy that antisemitism isn’t tolerated by this administration, period,” said Kaploun. Then, he said you turn to “quiet diplomacy to get results.”

For instance, he said Armenia has indicated to his office that its leaders are willing to join the International Holocaust Remembrance Alliance, an international organization that drafted a working definition of antisemitism that has been adopted by dozens of nations, including the U.S.. Kaploun also said he worked with U.S. Ambassador to Belgium Bill White to pressure Brussels to reverse its decision to end a federal police security presence in Antwerp’s Jewish quarter. 

Kaploun identified Hungary, Romania, Albania and Armenia as countries that are “making sincere efforts in dealing with antisemitism.” He said Turkey and Pakistan both leave “a lot to be desired currently,” and that “England is a particular concern” because of “the rise of mass migration.” 

The ambassador-level position has a global remit, but Kaploun was not afraid to weigh in on domestic antisemitism, too. 

“I think the best argument right now in this country to combat antisemitism and combat Holocaust denial is, you’re treading on the memories of every American soldier who fought tyranny, fought to liberate Europe from the Nazis and liberated the death camps,” said Kaploun, who also argued that ignorance about American Jewish history contributes to antisemitism — and called for people to argue that anti-Jewish hate is anti-American.

“It really is a lack of knowledge about the contributions of Jewish Americans to America, that people fled here for religious freedom,” Kaploun said. “That’s something that this country stands for. So when you are going against the same groups that have the same values, Judeo-Christian values, you are anti-American, because you’re going against what our founding fathers wanted for us.”

Kaploun has not yet announced any international trips. But his goal for all countries, he said, is a “basic human morality.”

“We’re far from getting every country on board,” said Kaploun.
