The recent case of the Bastille Day jihadist Mohamed Bouhlel is another reminder that the correct number of Muslim immigrants is ZERO, period, now and forever until pigs fly and Islam is reformed.

Unfortunately, there’s a wrong-headed idea floating around that Muslim immigrants can be successfully screened to keep out the dangerous bad guys. The truth is that jihad ideology is powerful and can re-emerge in the minds of Muslims at any time like a latent disease.

Achmed may test out as being a fine fellow on paper who doesn’t want to behead infidels, but that viewpoint cannot be guaranteed to last. At some point he may feel stressed or insufficiently virtuous or or not Islamic enough, and then decide he must return to the all-encompassing religion of his tribe. The switch can occur very quickly, as apparently happened with the Tunisian immigrant Mohamed Bouhlel who murdered 84 with a 19-ton truck at the Independence Day celebrations in Nice, France.

In a 2010 Wall Street Journal article, “Infiltrating Jihadis’ World,” a police informant associated with young men being turned to Islamic murder and observed their enjoyment of snuff films of American soldiers which inspired them to want to kill:

He said he watched the radicalization process of dozens. At times, it was so rapid that a year or two could separate clubbing in Miami from prayer five times a day.

So the process of radicalization can happen quickly, particularly when effective visuals are used.

In addition, young second generation immigrants seem particularly susceptible to jihad propaganda. When combined with the normal rebellion of youth against parents and authority, the jihad message can be quite powerful to the second generation, unfortunately.

As it happens, the immigrant Bouhlel drank alcohol, beat his wife and didn’t respect Ramadan. Too bad his general thuggery didn’t prevail, because he went jihad in a bad way.
