Antisemitism did not end with the liberation of the camps, and this History Hit documentary traces the line from Nazi propaganda to the hatred resurfacing across Europe and the United States today. Auschwitz survivor Irving Roth describes the machinery of dehumanization he lived through, while Kasim Hafeez, a former extremist, explains from the inside how young people get pulled toward radical ideologies and conspiracy thinking. Historians and psychologists break down the specific tactics propaganda uses, from scapegoating to dehumanizing language, and how those same mechanisms resurface in modern politics and online radicalization. The film moves between archival footage of Nazi Germany and present-day interviews, using the two survivors' accounts as anchors for a broader argument about how hatred gets manufactured and passed down. Rather than treating antisemitism as a closed historical chapter, the film treats it as a recurring pattern, asking what makes the same psychological triggers effective across generations. The result is a sober case for vigilance built on testimony rather than abstraction.
