Iran Warned of Terror Threat in U.S. if Nuclear Sites Struck, Say Officials
Washington, D.C. — U.S. officials have revealed that Iran issued a chilling warning during the G7 summit in Canada: if President Trump ordered strikes on Iran’s nuclear facilities, Tehran could activate sleeper-cell networks inside the United States to launch terror attacks, according to two unidentified American sources.
The message was reportedly communicated via an intermediary at the G7 gathering—just days before U.S. airstrikes targeted Iranian nuclear sites at Fordow, Natanz, and Isfahan. The strikes occurred on a Saturday night in what President Trump described as a “stealth mission” aiming to degrade Iran’s nuclear infrastructure.
Context and Response
-
The strikes prompted widespread concern over Iran’s intention to retaliate. U.S. intelligence and counterterrorism agencies are now reportedly monitoring potential sleeper-cell activity on American soil.
-
A Politico report highlights that alongside sleeper cells, Iran may resort to cyberattacks or targeted actions against U.S. forces and allies, raising the stakes of any further escalation.
Additionally, European diplomats echo the concern: Iran allegedly emphasized the capability to strike European and American nationals abroad if the nuclear facilities were hit.
Security Measures and Government Warnings
In response to the threat:
-
U.S. local law enforcement, including police departments in major cities, have reportedly increased patrols around diplomatic and cultural sites.
-
Nationwide, the Department of Homeland Security has escalated intelligence sharing with state and local agencies to detect early indicators of terrorist plots.
Government officials emphasize that sleeper cells are hard to detect and can blend seamlessly into communities—remaining dormant until activated.
Iran’s Strategic Calculus
Experts suggest that Tehran viewed the G7 message as a strategic deterrent, aiming to dissuade President Trump from expanding the strike beyond Israeli operations. It was never explicitly stated if the threat would be carried out—but intelligence analysts regard it as a signal of possible asymmetric warfare.
While Iran’s strike capabilities on U.S. soil remain debated, earlier Israeli operations have reportedly weakened Iranian nuclear and military infrastructure—something both U.S. and Western officials acknowledge.
The Road Ahead
-
Hundreds of American diplomatic, cultural, and scientific institutions have been advised to enhance security protocols.
-
DHS and the FBI are intensifying efforts to detect potential sleeper-cell activations, with proactive risk assessments conducted in urban centers.
-
Analysts warn that Iran may shift tactics toward cyber threats or influence operations if direct attacks are deemed too risky.
For the U.S. government, the challenge remains twofold: deter further escalation while maintaining domestic vigilance—without unnecessarily alarming the public.
