In the past 48 hours, the landscape of terrorist threats in the United States has remained fraught with ongoing concerns and new developments. The Department of Homeland Security (DHS) continues to emphasize that the country is in a heightened threat environment, driven by various factors including the activities of lone offenders and small groups motivated by a range of ideological beliefs and personal grievances.
Recently, the DHS issued an updated National Terrorism Advisory System (NTAS) Bulletin, highlighting the persistent and lethal threat posed by domestic violent extremists (DVEs) and those associated with foreign terrorist organizations. These groups continue to exploit online platforms to spread violent extremist narratives and promote violent activity. The bulletin notes that upcoming events, such as the 2024 general election cycle and legislative or judicial decisions on sociopolitical issues, could mobilize individuals to commit acts of violence. Potential targets include U.S. critical infrastructure, faith-based institutions, schools, racial and ethnic minorities, government facilities, and the LGBTQIA+ community[2].
In a recent briefing on January 7, 2025, members of the House Homeland Security Committee were updated on the investigation into the New Orleans terrorist attack that occurred on New Year’s Day. The FBI confirmed that the attack, which resulted in 14 deaths and over 30 injuries, was inspired by ISIS, but found no evidence of co-conspirators or that the suspect was on any federal government watchlists. This incident underscores the ongoing threat from foreign-inspired terrorism within the U.S.[5].
The rise in domestic terrorism incidents is also a significant concern. Between 2010 and 2021, there were 231 incidents of domestic terrorism, with the majority being racially or ethnically motivated, and anti-government or anti-authority motivated violent extremism being the second largest category. These incidents have been particularly lethal, with notable examples including the 2022 Buffalo shooting and the 2018 Pittsburgh synagogue attack[3].
To combat these threats, DHS and the FBI are enhancing their collaboration and information-sharing efforts. The Prevention Resource Finder (PRF) website, launched in March 2023, provides a comprehensive repository of federal resources to help communities mitigate and protect themselves from targeted violence and terrorism. Additionally, DHS’s Center for Prevention Programs and Partnerships (CP3) educates and trains stakeholders on identifying indicators of radicalization and preventing targeted violence[2].
The federal government's response to these threats includes increased investigations and prosecutions. The number of FBI domestic terrorism investigations has more than doubled since 2020, and federal district court prosecutions related to domestic terrorism have also seen a significant increase[3].
In summary, the United States remains under a heightened threat environment due to the activities of domestic and foreign terrorist actors. Recent incidents, such as the New Orleans attack, and ongoing efforts by DHS and the FBI to enhance security measures and information sharing, highlight the complex and evolving nature of these threats. Public vigilance and reporting of suspicious activities remain crucial in preventing acts of terrorism.
