Antisemitism has surged around the globe over the past decade, according to the Anti-Defamation League, an alarming trend that has largely been led by younger generations.

Nearly half of people worldwide hold antisemitic views, according to a new survey by the Anti-Defamation League (ADL). The Global 100 survey released in coordination with Ipsos on Tuesday found that 46 percent of the world’s adult population have antisemitic attitudes,

A fifth of the respondents haven’t heard of the Holocaust, during which six million Jews were killed, while 21% believe it has either been exaggerated by historians or it never happened.

Anti-Defamation League CEO Jonathan Greenblatt joins 'Squawk Box' to discuss the new survey results on the rise of antisemitic beliefs around the world, how to best combat antisemitism, and more.

Nearly half of adults around the world have “elevated levels of antisemitic attitudes,” the Anti-Defamation League reported in its latest global survey of anti-Jewish beliefs.  In addition, the survey found that one-fifth of the world has not heard of the Holocaust.

Antisemitic tropes and beliefs are becoming alarmingly normalized across societies worldwide,” said Marina Rosenberg, ADL Senior Vice President for International Affairs.
