We recently learned that at least one of the jihadists who killed 129 people in Paris held a Syrian refugee passport. And now a high-ranking Syrian diplomat says this may be just the tip of the iceberg.

The diplomat is Syria’s ambassador to India, Riad Abbas, and he recently related a shocking claim. Reported Sputnik:

In early September, media reported, citing an unnamed ISIL [Islamic State] operative, that an estimated 4,000 covert ISIL terrorists had arrived to Europe disguised as refugees.

“Among the refugees, who went to Europe, maybe more than 20 percent belong to ISIL groups. Now Europe has received bad element[s] into their ground. They will face further problem[s] in future," Riad Abbas said, commenting on recent deadly terrorist acts in Paris on November 13.”

According to the diplomat, terrorism has penetrated everywhere in Europe.

While it’s impossible to know if the numbers of Abbas are accurate, there’s no doubt the aforementioned Paris attacker was one of many terrorists to enter Europe via what Donald Trump has called the “Trojan Horse” of the Muslim migrant influx. In fact, many astute observers have long warned of this threat. Most notably, Dr. Mudar Zahran, a Muslim refugee living in the United Kingdom, recently called the Muslim migrant phenomenon the “Islamic conquest of the West” and stated that most of the migrants are not what they seem.

Appearing on an October segment of “The Glazov Gang,” he characterized the migration as an “influx of all kinds of refugees from the Middle East.” He then explained that “75 percent of those arriving from Syria come from safe area[s]; actually, the ones in disaster areas cannot ... leave. So, actually, as much as there’s a disaster in Syria, most of those people arriving do in fact do not need the protection.” Yet he pointed out that the West may need protection from them, saying, “I can authoritively [sic] confirm — I have photos, I have images, I have pictures, I have names of terrorists who actually are already in Europe posting their photos in Europe on Facebook.”

And just under a month later, the Paris attack apparently proved him to be quite the prophet.

Zahran elaborated further and delivered more bad news. Half the Syrian male migrants “have actually held weapons and fought in the Syrian war,” he said. And while they’re rough and ready to fulfill what he terms “the Islamic … dreams of fascism of some,” Europe is playing the doormat. What Muslims “couldn’t do in the last 20 years,” says Zahran, “now the West is doing for us for free — and even paying for it.” Moreover, Zahran had this shocking news about the “invasion”: “I have to be honest,” he said, “you read Arab magazines and Arab newspapers; they are talking about, ‘Good job! Now we’re going to conquest [sic] Europe.’ So it’s not even a secret.”

What Zahran warns of relating to this “conquest” is “actually an ancient strategy, straight from the Islamic playbook[,] called The Hijra (Arabic: هِجْرَة‎ hijrah) ... the migration or journey,” wrote Michele Hickford at ex-congressman Allen West’s website in September. She continued, “Hijra is one of the most effective methods of jihad which requires no military or wars. But it is an invasion nonetheless, and the politically-correct, humanitarian West is inviting it with open arms.”

Yet it is an invasion that can include warriors. Defenders claim this problem can be avoided with proper “vetting.” As CNN reports today, “On NBC's ‘Meet the Press’ Sunday, White House Deputy National Security Adviser Ben Rhodes said, ‘We have very extensive screening procedures for all Syrian refugees who have come to the United States. There is a very careful vetting process that includes our intelligence community, our National Counter Terrorism Center, the Department of Homeland Security, so we can make sure that we are carefully screening anybody that comes to the United States.’”

But, CNN continued, “New York Rep. Peter King, speaking on Fox News, cast doubt on Rhodes' comments. ‘What he said about the vetting of the refugees is untrue. There is virtually no vetting [‘]cause there are no databases in Syria, there are no government records. We don't know who these people are.’” Note that King’s assessment has been echoed by U.S. intelligence officials.

This confronts us with a simple matter of probability: If one million unvetted migrants enter a nation over time and just 1/10th of one percent are terrorists, that’s 1,000 dangerous jihadists. Is this acceptable?

Yet there’s also a fundamental problem with vetting that goes unmentioned: even with complete information, it tells you only about the past.

It cannot tell you about the future.

In other words, even if those one million migrants have “clean records,” how many will become terrorists in the future? Again, 1/10th of one percent is 1,000.

And what of their children? How many of them will become terrorists? One response here is that the children will be more integrated and thus the problem should diminish over time. This is logical, but, unfortunately, also apparently untrue. For studies have shown that young Muslims in Europe are actually more radical than their elders.

Despite this, powerful forces are militating for increased Muslim migrant resettlement in the United States. Barack Obama vowed to forge on ahead with the process, and the prevalence of multiculturalism and religious-equivalence doctrine have blinded many to problems inherent in such wide-scale migrations. Moreover, as American Thinker’s James Simpson points out in today’s piece “Resettlement Contractors Lie to Protect Their Franchise,” organizations involved in “refugee” resettlement sometimes have communist ties and also, acting as consummate capitalists, make big money off their facilitation of Hijra.

Unfortunately, say critics increasingly proven correct by current events, it’s money that will be paid for in blood.
