Antisemitism is no longer a temporary surge but a structural threat driven by political extremism, institutional distrust and social media, Anti-Defamation League chief executive Jonathan Greenblatt has warned. Greenblatt said the change since he took over the ADL in 2015 has been profound. Foreign actors exploit open democratic systems, while traditional media has collapsed and social media has filled the vacuum. “Social media doesn’t have any of the checks and balances … Social media itself is a hellscape of antisemitism, and an environment where AI is wiring everything has the potential to be even worse.” “Social media was intended to be a way for people to connect, not for mechanised campaigns to overrun the systems,” he said.
