About this listen

 In the past 48 hours, the landscape of terrorist threats in the United States has remained a pressing concern, with several key developments and ongoing trends highlighted in recent reports and assessments.

The Department of Homeland Security's (DHS) latest Homeland Threat Assessment 2025 underscores the persistent and evolving nature of terrorist threats. According to the report, Domestic Violent Extremists (DVEs) and other criminal actors are likely to continue targeting critical U.S. infrastructure, driven by various ideological and sociopolitical motivations. These attacks often involve lone offenders or small groups employing simple tactics that require minimal technical knowledge or preoperational planning.

The ongoing Israel-HAMAS conflict has exacerbated these threats, with Foreign Terrorist Organizations (FTOs) like ISIS and al-Qa‘ida issuing calls for lone offender attacks against U.S. critical infrastructure, including government buildings and foreign embassies. Specifically, al-Qa‘ida and its affiliates have renewed these calls in response to recent events in Gaza, posing a heightened risk to U.S. interests[1].

The National Terrorism Advisory System (NTAS), managed by DHS, continues to play a crucial role in communicating terrorist threats to the public. While there have been no new NTAS advisories issued in the past 48 hours, the system remains vigilant in monitoring and reporting any changes in the terror threat landscape. The NTAS replaced the color-coded alerts of the Homeland Security Advisory System in 2011 and is designed to provide timely and detailed information to the American public[3].

The FBI has also emphasized the multifaceted nature of the terrorist threat facing the United States. International terrorism, while still a significant concern, is complemented by the rising threat of domestic extremism. Right-wing terrorism, in particular, has been identified as a major contributor to terrorist incidents in the U.S., outpacing other types of terrorism in recent years. This trend is expected to continue, with potential escalations around significant events such as election cycles[5].

In summary, the terrorist threat environment in the United States remains complex and dynamic, with both domestic and international actors posing significant risks. The recent calls for attacks by FTOs and the ongoing activities of DVEs highlight the need for continued vigilance and cooperation among law enforcement, intelligence agencies, and the public to mitigate these threats.
