The militant pro-Israel group Betar US has been added to the Anti-Defamation League's extremism database, leading to a clash between the two organizations. Betar has responded by adding the ADL to its own list of extremist organizations and making baseless claims about ADL staff. The incident reflects a deeper divide in approaches to fighting antisemitism among American Jews, with the ADL focusing on education and coalition-building, while newer groups embrace more confrontational methods. The ADL's glossary entry on Betar criticizes the group's tactics and associations, including with the far-right group Proud Boys.
