Three thwarted terrorists were arrested in Germany and one in Holland in connection with one planned attack, and three others were arrested in Denmark for a separate threat. Police got there before any of those plots were executed.
Col. Bob Maginnis, a national security expert at the Family Research Center, says the seeds for terrorism were planted in Europe years ago.
"They had a massive illegal immigration issue from the Middle East and north Africa, which is predominantly Islamist, a decade ago," he recalls. "What we've experienced over the last several years, thanks to Mr. Biden, is much the same."
He says western Europe has been a particularly welcoming home to many radicalized Islamists.
"When you begin to pick these people up in Denmark and Germany and Holland, and I'm sure they're in Italy and France and elsewhere, this is probably to be anticipated," says Maginnis. "I'm surprised we haven't seen much of it already."
Meanwhile, the U.S. terrorist watchlist has grown to more than 2 million people – nearly doubling in the last six years. Keeping track of that many potential terrorists, Maginnis tells AFN, is more than a daunting task.
"You don't," he admits. "There's no way. We don't have enough federal agents, and so local people have to monitor and be suspicious and report."
The FRC spokesman goes on to warn that President Biden's lax border policies have turned the U.S. into a tinderbox of activity that could rain down on the American public in the near future.
"I think the internal threat level is probably, on a scale of one to 10 and 10 being the highest, it's probably at an eight," Maginnis figures.
Agents must have "reasonable suspicion" to put a person on the watchlist, and the vast majority of those listed are not U.S. citizens or legal permanent residents.
