Something I've been fearing for quite awhile; sleeper cells within the U.S. Brandon I'm sure let in plenty of terrorists/extremists.
Enemy within: Counterterrorism experts fear sleeper cells could be poised inside USAmerican counterterrorism agencies are quietly monitoring suspected sleeper cells on U.S. soil in the wake of joint U.S.–Israel strikes on Iran, stepping up surveillance amid heightened fears of possible retaliation from Iran-linked operatives or sympathizers.
Federal and local law enforcement have also boosted on-the-ground security in major U.S. cities as part of a precautionary posture, even though no specific, credible threats have been publicly identified.
The move comes on the heels of a Saturday morning operation, dubbed Operation Epic Fury, that resulted in the death of Iran’s Supreme Leader Ayatollah Ali Khamenei and several senior Iranian officials in a coordinated U.S.–Israeli military campaign.
Security experts warn that the fallout could extend beyond the Middle East.
"If ever there's going to be a Hezbollah cell or a Hamas cell act in the United States in a violent way, it's now," Chris Swecker, a former assistant FBI director, told Fox News.
"Both organizations are Iranian-backed all the way. Both organizations have had a presence in the United States since the 1980s," he added.
Swecker said U.S. authorities have long been aware of domestic networks and sympathizers.
"We know that they have cells here. We also know that there are lone sympathizers, many of whom have come out in these protest groups," he added.
He also warned that border security vulnerabilities may have compounded the risk.
"We just come off four years of open borders, and I have said before that that was an open door for terrorists to terrorist cells and terror sympathizers to infiltrate. Many were already here, but it's impossible that they would not infiltrate into these particular groups and sort of act as catalysts, as enablers."..........
