U.S.–Iran Conflict and Homeland Security

A DHS memo warned of potential Iran‑linked lone‑actor violence and lower‑level cyberattacks tied to recent U.S.–Israeli strikes, prompting FBI Director Kash Patel to order federal counterterrorism and Joint Terrorism Task Force units to mobilize and remain on high alert while investigators probe the Austin mass shooting amid reports of Iranian symbols, though no specific, credible plots have been publicly identified. Federal, state and local agencies — from U.S. Northern Command and Capitol security to NYPD, LAPD and transit police — have increased protections as more U.S. tactical assets flow to the Middle East, and officials warn the response could be hampered by a roughly month‑long DHS funding lapse that may furlough CISA staff.
