Oct. 7 reshaped US terror threat landscape, new House report says

A new 130-page report from the House Committee on Homeland Security, titled "National Security Improvements and the Domestic Threat Landscape 25 Years After 9/11/01," warns that the October 7 attacks "significantly altered the terrorism threat environment" in the U.S. and globally. Released on Thursday, the report indicates a sharp increase in antisemitic violence and extremist mobilization inspired by the Israel-Hamas conflict. It highlights the continued influence of groups like Hamas and Hezbollah despite losses, citing their propaganda and media operations, and notes a more than 300% rise in radicalized young people without formal extremist ties over the past decade. The report also identifies persistent intelligence-sharing problems among federal, state, and local agencies, stating that "Intelligence is often present but not integrated or shared with the appropriate partners to form a common threat picture." Recommendations include increased scrutiny of extremists' social media and AI use, and enhanced intelligence sharing with allies. Rep. Andrew Garbarino, committee chair, emphasized that this "no-fail mission requires persistent vigilance and adaptation to keep pace with the contemporary threat environment."
