• Federal agencies operate under strained conditions due to funding delays, impacting security updates.
  • Operation Epic Fury prompts concerns over retaliatory cyberattacks and rare lone-wolf attacks.
  • Iran's missile strikes and regional aggression threaten critical infrastructure and global energy stability.

Homeland Security Secretary Kristi Noem has warned senators that recent U.S. military actions against Iran, including strikes under Operation Epic Fury launched on February 28, 2026, have elevated the risk of retaliatory attacks on American soil. In testimony, she highlighted that federal agencies like the Coast Guard and Secret Service are navigating a heightened security environment without additional funding, as appropriations remain stalled since February 17, 2026, due to political gridlock.

As Operation Epic Fury entered its second day on March 1, 2026, DHS issued bulletins outlining potential threats, such as low-level cyberattacks—including DDoS incidents and website defacements—and physical attacks by Iran-inspired extremists. A DHS law enforcement bulletin noted persistent risks from Iran and its proxies, particularly if the Ayatollah's death is confirmed, with concerns focusing on U.S.-based violent extremists targeting Jewish, pro-Israel, or government-linked sites. No National Terrorism Advisory System (NTAS) alert has been issued yet, despite precedents like the June 2025 Operation Midnight Hammer, which triggered similar warnings.

Iran retaliated on March 2 with missile and rocket strikes on Israel and Arab neighbors, escalating regional tensions. An Austin, Texas, shooting on March 1, where the suspect wore Iran-themed clothing, is under investigation for possible inspiration, underscoring fears of lone-actor incidents. Efforts to reach DHS officials for further comment on the investigation were unsuccessful, but sources familiar with the matter indicate that behind-the-scenes intelligence sharing has intensified nationwide.

Economically, Iran's strikes threaten regional oil infrastructure, differing from June 2025 events by involving more aggressive pushback that could disrupt refineries and global energy markets. While no direct impacts on U.S. companies have been noted, heightened threats are expected to elevate security costs for critical infrastructure across the country. President Trump has vowed further "big wave" strikes and hinted at eventual negotiations, but Tehran has rejected talks amid distrust from prior conflicts, and the administration has not ruled out ground troops.

Societally, risks target mass transit, venues, worship sites, schools, and infrastructure, prompting increased police patrols. The public may face indirect effects through disrupted travel or events, with experts noting a persistently dangerous global environment akin to post-9/11. Historically, Iran favors asymmetric retaliation via proxies and cyber means to avoid escalation, as seen after Operation Midnight Hammer, which raised concerns about sleeper cells and undocumented entries.

Looking ahead, short-term risks include escalated low-level cyber threats and lone attacks, with coordination across agencies hampered by funding gaps. Long-term, potential regime destabilization in Iran could spur broader proxy alliances, such as with Venezuelan or cartel elements, amplifying homeland disruptions. Analysts predict continued Iranian aggression, urging updates to NTAS alerts to better inform the public and stakeholders.
