Immigration Minus Assimilation Means Conflict
Daniel J. Flynn writes at The American Spectator that terrorists are often on the dole before they murder:

The ex-wife of Ibrahim Abdeslam, who blew himself up in last Friday's Paris attacks, says he worked one whole day during their two-year marriage. Instead of labor, he slept during business hours, watched DVDs, and smoked "alarming" amounts of marijuana every day while blaring Arabic rap music. She told the Daily Mail, "We lived on unemployment benefit which was only €1,000 a month between us so we worried a lot about money."

...Before he blew himself up outside a French soccer stadium, Bilal Hadfi lived in state-subsidized housing. Like so many, he hated his landlord. His Facebook page shows him drinking, raising his middle finger, and aiming a firearm. He failed his school exams and confessed an addiction to video games. He repeatedly posted the message (pardon my French) "Nique de police."

...Many of the terrorists displayed more decadence than devotion. Boulahcen's brother maintains she never read the Koran. The headmaster at Hadfi's Belgium school says he "wasn't especially religious." Abdeslam's wife notes that he refused to go to mosque.

...Open wallets as much as open borders doom Europe. Harboring shiftless populations alienated from the surrounding culture by religion asks for trouble. Give them blank checks and watch them fill up the blank spaces of indolence with destruction. We hate our benefactors.

The Islamists understand the tolerance and multiculturalism of the West as weaknesses to exploit rather than kindnesses to reciprocate. They pay back the dole with gunfire. Ahmed Almuhamed, saved off a sinking refugee boat by the Greeks, returned the favor by shooting up a packed concert hall. The English language lacks a word describing such off-the-charts ingratitude. Perhaps the French now have one. Almuhameditude?

"The underlying problem for the West is not Islamic fundamentalism," Samuel Huntington concluded two decades ago in The Clash of Civilizations. "It is Islam, a different civilization whose people are convinced of the superiority of their culture and are obsessed with the inferiority of their power.
