The Looming Threat: Iranian Illegal Aliens and Potential Sleeper Cells Under Biden’s Watch

A chilling national security concern has resurfaced following recent U.S. military strikes on Iran’s nuclear facilities. The focus is on the hundreds of Iranian nationals who illegally entered the United States during the Biden administration and were subsequently released into American communities, raising fears of potential terror sleeper cells poised to strike. This situation underscores the catastrophic consequences of lax border policies, exposing vulnerabilities that threaten the nation’s safety and sovereignty. The timing, amid heightened tensions with Iran, amplifies the urgency of addressing this self-inflicted crisis.
Data from the past four years reveals a troubling trend. Between fiscal years 2021 and 2024, Border Patrol agents apprehended 1,504 Iranian nationals attempting to cross the southern border illegally, with 729 of them released into the U.S. interior. The numbers escalated annually: 48 apprehensions in 2021, 197 in 2022, 462 in 2023, and 797 in 2024, with releases rising from 12 to 448 over the same period. All Iranian nationals are classified as “special interest aliens” due to national security concerns, requiring enhanced vetting—a process that appears to have failed given the scale of releases. Additionally, over 2 million “gotaways”—individuals who evaded capture—entered during this time, leaving their identities and origins unknown, further complicating the threat assessment.

The Biden administration’s border policies have come under scrutiny as evidence mounts of terrorist risks. Reports indicate that nearly 600 individuals with ties to terrorism were paroled into the country after illegal entry, while over 385 terror watchlist encounters occurred at the border since 2021—a stark increase from the 14 recorded during the previous four years. Among these, Iranian-backed plots disrupted since 2020, and the recent military strikes on June 22, 2025, have prompted warnings of retaliatory actions, including the activation of sleeper cells. A Department of Homeland Security bulletin highlights the risk of violent extremists mobilizing if Iran issues a call for retaliation, a scenario made more plausible by the presence of unvetted Iranian nationals.

What the hell have they been doing?

This crisis reflects a deliberate neglect of America’s security. The Biden administration’s catch-and-release practices, coupled with inadequate vetting, have potentially seeded the nation with operatives from a state sponsor of terrorism. The June 22 strikes, ordered by the current administration, have intensified the threat, with experts warning that thousands of Iranians who crossed the border remain untracked. The contrast with current border enforcement—where no illegal immigrants were released in May 2025—highlights the prior administration’s failures. Critics argue that prioritizing humanitarian rhetoric over national defense has left the homeland exposed to an unprecedented security risk since 9/11.
The establishment narrative may downplay these concerns, citing the small fraction of watchlist hits relative to total border encounters. However, the sheer volume of unvetted entries and the strategic intent of Iran, which has vowed retaliation, cannot be dismissed. Posts found on X reflect growing public alarm, with some estimating over 1,200 Iranians released, though such figures remain unverified. Citizens demand accountability and immediate action—enhanced surveillance, expedited deportations, and a fortified border—to neutralize this threat. As tensions escalate, the nation cannot afford to ignore the sleeper cells that may already be in place, waiting for the right moment to strike.
