Some time ago a former student emailed me a video clip that I now show my Major European Governments course. It’s a five-minute news piece by Dale Hurd of CBN News, a conservative Christian outlet — the rare kind of place where you see reports like this. The piece was on radical Islam in Europe, specifically in Belgium, and it was based on Hurd’s interview with a Muslim leader in Brussels, the very heart of modern Europe, of secular Europe, of the European Union, and of everything Islamic fundamentalists despise about Europe.

“Allah makes the laws and tells us what is allowed and what is forbidden,” Abu Imran told Hurd.

Imran is leader of Shariah for Belgium, and insists there’s no such thing as a “democratic Muslim.” Such a notion, he maintains, is as absurd as a “Christian Jew” or “Jewish Muslim.” “It’s impossible.”

Imran says that real Islam and Shariah law are “inseparable.”

Imran’s group wants what it calls “Belgistan,” and foresees Brussels as an “Islamic capital” within mere decades. He cites numbers to back his optimism. Imran says that in some cities in Belgium, such as Antwerp, 40 percent of the children in schools are Muslim. And though Muslims comprise only 25 percent of religious believers in the country, that is enough to make them the largest religious group, given that Belgium, like most of Europe, has rapidly de-Christianized. Imran’s group expects Muslims to be the majority in Belgium within 20 years.

Notably, that rise is coming from nothing unusual among Muslims. They are simply reproducing, whereas natives of Belgium, like natives of Europe, are not. For many modern Europeans, sex is about recreation, about fully separating intercourse from reproduction, about having as much sex as possible without the undesired outcome of a child. For faithful Muslims, sex is still about babies.

Like many major European cities, from London to Oslo, the most popular baby name in Brussels last year was “Mohammed.” In fact, reported Dale Hurd, “Mohammed” was the most common baby name in Brussels each of the last four years. I do not see that trend changing anytime soon.

Dale Hurd noted in his report that Shariah for Belgium is a “small group that a lot of people do not take seriously.” I bet they are now.

Obviously, I’m sharing this with readers now because the ringleaders of the terrorist assaults in France last week — the worst attacks inside France since World War II — were reportedly based precisely in Brussels.

Unlike Mr. Imran and his group, the ISIS-affiliated Muslims who attacked last week are blatant jihadists. They aren’t patient enough to wait for their babies to grow to adulthood. They’re not awaiting a demographic time-bomb to bring Islam to Europe. They want “victory” now. They are happily (yes, happily) willing to detonate themselves at this very moment. Their method is bombs rather than babies. They don’t want victory via life by outgrowing native Europeans. They want victory via death by killing native Europeans.

Regardless of those violent methods, Islam is poised to triumph in Europe in the long-run. Over time, a native population that fails to do the most rudimentary thing of any native population — that is, give birth to the next generation — will by sheer sex and math give way to the outsiders who have entered the country and are giving birth to the next generation. Muslims in Europe can make love, not war — love that brings babies rather than blocks babies.

The clashes we are witnessing between ex-Christian Europeans and current Muslim Europeans is just the start. The Europe of the 21st century is going to be extremely chaotic.
