“Those who cannot remember the past are condemned to repeat it,” Spanish philosopher George Santayana warned us.

A new survey by Claims Conference, an organization seeking justice for Holocaust victims, suggests that the U.S. is becoming dangerously close to forgetting the Holocaust. The survey shows that a significant portion of the population is woefully misinformed about its horrific details. 

Thirty-one percent of all Americans and 40 percent of Millennials do not believe six million Jews died in the Holocaust, but 2 million or less, according to the survey. Forty-five percent of Americans are also unable to name a single concentration camp.

Harvard Business School historian Nancy Koehn joined Boston Public Radio Tuesday to talk about these startling revelations.

"We are living in a time when these kinds of numbers, this kind of survey, makes us a little bit more anxious given the rise of authoritarianism, given the rise of all kinds of projections of enemy status on different people from immigrants, to Jews to African-Americans, to all kinds of folks,” said Koehn.

Koehn pointed to the rise of antisemitism around the world, and specifically, the display of neo-Nazi rage last year during the protests in Charlottesville, Virginia.

“It is the systemization of this kind of evil, practiced against a single group of people, under a regime that is democratically elected, that to me is so frightening,” Koehn said.
