New Podcast Examines Link Between Propaganda, Conspiracies and Violent Extremism

In an increasingly polarized political landscape, propaganda and conspiracy theories are playing a pivotal role in fueling violent extremism across the United States, according to extremism experts featured in a new podcast episode.

The discussion, titled “Why Conspiracies and Propaganda Fuel Violent Extremism,” brings together renowned scholars Cynthia Miller-Idriss and Bill Braniff from the Polarization and Extremism Research Innovation Lab (PERIL), who examine how harmful narratives spread and contribute to radicalization.

Miller-Idriss emphasized that prevention efforts should focus on helping people recognize manipulative tactics. “What we know from our work is that it’s more effective to prevent people from being persuaded by propaganda and conspiracy theories by pointing out the manipulation,” she explained during the interview. She highlighted the importance of teaching individuals to identify “outrage politics” and content designed to profit from their engagement or lead them toward harmful ideologies.

The experts detailed how prejudice-driven narratives—particularly those centered on misogyny, antisemitism, and anti-minority sentiment—continue to gain traction in American society. The digital landscape has dramatically accelerated this problem, with online platforms serving as efficient delivery mechanisms for extremist content.

The conversation comes against a backdrop of concerning incidents across the country. The scholars specifically referenced a March 12 attack in Michigan where Ayman Mohamad Ghazali allegedly drove a vehicle into a synagogue. According to reports, Ghazali claimed his actions were motivated by Israeli military operations in Lebanon that resulted in the deaths of his family members.

This incident exemplifies how international conflicts can trigger domestic extremism—a growing concern for terrorism prevention experts.

Braniff, who also serves as Editor-at-Large for Homeland Security Today’s Terrorism Prevention vertical, expressed alarm about the current trajectory of prevention efforts. “By and large, the U.S. government has entirely receded from the primary prevention space,” he noted grimly. “We’re well behind where we were a year ago.”

This apparent reduction in federal prevention programs comes at a particularly dangerous time, the experts suggest. With political tensions escalating ahead of a contentious election season and international conflicts generating strong emotional responses domestically, the infrastructure to counter extremist radicalization appears to be weakening precisely when it’s most needed.

The podcast highlights how preventative approaches differ from law enforcement interventions that occur after someone has already embraced extremist ideologies or committed acts of violence. Effective prevention requires identifying vulnerable individuals before radicalization fully takes hold and providing them with the critical thinking tools to resist manipulation.

Recent studies from organizations tracking extremism have documented a significant increase in antisemitic incidents across the United States in the past year, with similar rises in anti-Muslim and anti-immigrant rhetoric following international conflicts and domestic political events.

The conversation between Miller-Idriss and Braniff represents part of a growing body of research suggesting that extremism prevention requires a multifaceted approach involving education, community engagement, and targeted intervention programs. Their work at PERIL focuses on developing evidence-based tools to reduce polarization and prevent extremist radicalization.

The experts concluded that without renewed focus on prevention strategies, the United States risks facing more incidents of ideologically motivated violence. They advocate for increased funding and attention to programs that can identify early warning signs of radicalization and provide communities with resources to counter extremist narratives before they lead to violence.

As digital platforms continue to evolve and global conflicts persist, the challenge of countering propaganda and conspiracy theories that fuel extremism remains one of America’s most pressing national security concerns.
