It’s still a mystery who created the document, or if the teachers who distributed it will face any consequences.

A New York school district distributed a study guide for a state-issued exam that described Zionism as “extreme nationalism” and accused Israel of “terrorism.”

The watchdog group StopAntisemitism posted a photo of the study guide, which was meant to prepare 10th graders for New York’s Regents Exam, and called it “straight out of a Hamas playbook.” It’s unclear who made the document or why it was given out to students.
