The Threat - PoE Substack
In March 2026, we launched a new Substack publication, The Threat. Edited by Jay Solomon, the publication builds on his podcast of the same name and serves as a platform for deeper analysis, timely insights, and practical perspectives on extremism and its impact on societies.
Through The Threat, Jay will publish original reporting, commentary, and analysis, alongside contributions from researchers and staff at the Program on Extremism. Together, the publication will feature work from across our four core areas of focus: antisemitism, Islamism, global jihadism, and domestic extremism, including analysis of radicalization, terrorism, and emerging extremist movements, as well as policy-focused perspectives.
We encourage you to subscribe to The Threat on Substack to receive new posts directly in your inbox. Subscribing is free and ensures you don’t miss the latest writing, analysis, and research from Jay and the Program on Extremism team.
