Counter-intelligence experts and security officials are warning of the risk that terrorist “sleeper cells” could seek to retaliate on U.S. soil following the joint U.S.–Israel airstrike campaign against Iran.
Although no specific threats have been publicly announced, counter-terrorism agencies have increased resources to monitor and prevent potential risks, according to sources familiar with the situation.
Former FBI Assistant Director Chris Swecker noted that if groups like Hezbollah or Hamas intend to carry out violent acts in the U.S., this could be a sensitive time. He also suggested that loose border policies in recent years might facilitate the entry of extremists.
According to a previously disclosed internal memo, more than 700 Iranian citizens have been allowed to stay in the U.S. after crossing the border illegally over the past four years, raising concerns about the potential infiltration of extremists. However, there is no public evidence showing these individuals are linked to terrorist activities.
FBI Director Kash Patel stated that he directed counter-terrorism and intelligence units to be on high alert as soon as the military operation began. He emphasized that teams across the country are working around the clock to detect and neutralize any threats.
Secretary of Homeland Security Kristi Noem also confirmed she is coordinating closely with federal partners to monitor the situation and protect homeland security.
Law enforcement officials emphasized that there is currently no confirmed information regarding a specific attack plan, but precautionary measures have been strengthened amid escalating tensions in the Middle East.
