In the latest assessments and reports, the landscape of terrorist threats in the United States remains complex and multifaceted, with several key areas of concern highlighted by recent intelligence and security analyses.
According to the Department of Homeland Security's (DHS) 2024 Homeland Threat Assessment, terrorism, both foreign and domestic, continues to pose a significant threat to the homeland. The report indicates that the threat of violence from individuals radicalized in the U.S. will remain high but largely unchanged, characterized by lone offenders or small group attacks with little warning. Foreign terrorist groups such as al-Qa’ida and ISIS are actively seeking to rebuild their overseas networks and maintain global support bases that could target the U.S.[1].
Domestic violent extremists (DVEs) and homegrown violent extremists (HVEs) inspired by foreign terrorist organizations have been particularly active. Since January 2022, DVEs have conducted several fatal attacks, resulting in 21 deaths and multiple non-lethal incidents. These attacks have targeted a variety of sectors, including law enforcement, government, faith-based organizations, and retail locations. The most lethal attack in recent times occurred in May in Allen, Texas, where an attacker killed eight people at a shopping mall[1].
The Center for Strategic and International Studies (CSIS) has also reported a significant rise in domestic terrorist attacks and plots motivated by partisan political beliefs. Over the past five years, such incidents have nearly tripled compared to the previous 25 years combined. These attacks have primarily targeted government, military, and law enforcement entities, as well as elected officials and political candidates. This trend is largely driven by the spread of conspiracy theories and violent rhetoric[3].
In addition to these threats, the 2024 election cycle is anticipated to be a focal point for potential violence and foreign influence. Nation-state adversaries are expected to ramp up their mis-, dis-, and malinformation campaigns to undermine U.S. social cohesion and election processes. The DHS has emphasized the need for heightened vigilance and security measures to protect election infrastructure, processes, and personnel[1].
The financial aspect of terrorism also remains a concern. The 2024 National Terrorist Financing Risk Assessment highlights that individuals inspired by AQ, ISIS, or DVE ideologies continue to pose the primary terrorism threat to the homeland. These individuals often radicalize online and can carry out deadly attacks with minimal warning. The report also notes that terrorist financing methods have evolved, with many individuals now focusing on attacks within the U.S. rather than sending funds to foreign terrorist groups[5].
In response to these threats, U.S. law enforcement and security agencies have increased their efforts to enhance protective security measures, strengthen response plans, and counter the spread of disinformation. Congress has authorized additional spending on Capitol security, personal security for lawmakers, and investigative and security forces to combat domestic terrorism[3].
Overall, the current terrorist threat landscape in the U.S. is marked by a blend of foreign and domestic threats, with a significant emphasis on lone actors and small groups inspired by various ideologies. As the country approaches the 2024 election cycle, maintaining robust security measures and public awareness remains crucial in mitigating these threats.
