WASHINGTON — As Operation Epic Fury enters its most aggressive phase, intelligence officials and national security experts are raising the alarm over a potential “second front” of the conflict: the activation of Iranian-backed sleeper cells within the United States.
The warnings, echoed in reports from the Daily Mail and other major outlets, follow a series of high-profile security incidents that have put the nation on high alert. Intelligence communities are currently evaluating the risk of asymmetric retaliation after the death of Ayatollah Ali Khamenei and the systematic dismantling of the Iranian regime’s leadership structure.
A ‘Clear and Present’ Domestic Threat
Counterterrorism experts warn that Tehran has spent decades cultivating a network of “sleeper” operatives, clandestine cells that remain dormant for years while gathering intelligence and scouting high-value targets.
“The goal of these cells is not just to disrupt infrastructure, but to instill a deep sense of fear within the American public,” stated one senior security analyst. Potential targets include:
-
Transportation Hubs: Major airports and rail systems in metropolitan areas.
-
Iconic Landmarks: Sites such as the Statue of Liberty have historically been cited in thwarted plots.
-
Soft Targets: Rural areas or outdoor entertainment venues that lack the heavy fortification of government buildings.
Fears were further stoked following a deadly mass shooting in Austin, Texas, on March 1, involving a suspect with alleged ties to Iran. A separate gun attack on an Iranian dissident’s gym in Canada has also been linked to the broader wave of retaliatory violence.
‘Cross-Border’ Vulnerabilities
The Department of Homeland Security (DHS) is currently reviewing immigration data amid concerns that operatives may have exploited border vulnerabilities to enter the country. Since mid-February, over 130 Iranian nationals have been arrested by U.S. Immigration and Customs Enforcement (ICE) as part of a preemptive vetting surge.
“You have people who may have a strong affiliation to Iran here for the express purpose of acting against us,” noted Bernard Zapor, a former official at the Bureau of Alcohol, Tobacco, and Firearms (BATF).
Cyber and Digital Warfare
Beyond physical violence, the U.S. is bracing for a “digital barrage.” Intelligence indicates that Iran’s cyber forces, though currently struggling to maintain their own domestic internet access, can target American banking systems and power grids via intermediaries and digital avenues.
As President Trump maintains his “ferocious” stance in the Persian Gulf, federal agencies have urged local law enforcement and faith institutions to remain vigilant. The message from Washington is clear: while the primary battle is being fought thousands of miles away, the threat of retaliation is as close as the American heartland.
