October 7 cast a destructive shadow not only over the men, women, and children caught on the battlefields of Gaza but also over the educators and journalists expected to explain why and how it happened. Despite its brutality, Hamas won substantial support on campuses, in the media, and from an array of progressive movements. The Hamas attacks, astonishing in their ambition, can only be fully understood by examining the world's responses to them, and telling the full story of October 7 requires data-driven and textual analysis. This is a rare combination, but one that makes this volume distinctive and essential for all those who want to understand how such a nightmare both reflects our twenty-first-century world and permanently changes it.
