Muslim immigration to Western Europe began by stages after the Second World War as labor-short economies and the end of empires combined to draw non-Europeans toward the “mother country.” A great deal of thoughtlessness went into these migrations. All host countries were ill-prepared to deal with the immigrants.
In January 2015 there are an estimated 20 million Muslims in Europe. About 5 million are in France, where they make up 8 percent of the population. (See: “The other land of liberty and opportunity.”) In Britain and Germany they make up 5 percent of the population. One of the things that eats at European countries is the feeling that immigrants have come to their countries to prey on the generous social welfare provision of enlightened countries. In the 1970s, two-thirds of the immigrants in Germany were in the labor force, while one-third were not. Thirty years later scarcely more than a quarter of immigrants were in the labor force. Another problem, revealed by a poll in L’Express in January 2013 is that 74 percent of those polled said that Islam “is not compatible with French society.” Yet this feeling finds no expression in the “mainstream” or “respectable” French political parties. Why not?
Christopher Caldwell argues that the European left has made discussion of the problems raised by immigration almost impossible. On the one hand, they have evoked European historical crimes—the Holocaust above all—to justify repressing unwelcome speech. He implies that they have undermined the foundations of democracy in the process. In France, he sees the “SOS Racisme” group created in the 1980s as a puppet of the Socialist Party intended to shout-down conservative voices and the 1990 Gayssot Law against Holocaust-denial as an entering wedge for people who want to stifle discussion of other historical events—many of them highly unpleasant and non-Western. Most recently, the anti-immigrant Front National Party got left out of the post-Charlie Hebdo parade on the grounds that it was not “republican” enough.
On the other hand, people on the left have failed to understand that, whatever was done to European Jews, it wasn’t done by Muslims. Just as Palestinians have felt free to reject the State of Israel as European expiation of European crimes at the expense of Arabs, so too have Euro-Muslims felt free to reject European progressive thought as an alien set of values intended to curb their own beliefs. If one adds these forces to the failure to integrate the immigrants and their French-born descendants into French society, one can begin to understand some of the impulses that set the Kouachi brothers and Amedy Coulibaly on the path to terrorism. They are not alone in their alienation, hostility, and religious fervor.
Caldwell understands that Europe’s aging and declining non-Muslim population makes immigration essential. He is less quick to say that the anti-immigrant and anti-Muslim sentiments expressed by parties like the Front National can have no practical expression in public policy. Yes, the Jews were expelled from Spain in 1492. Is that what the Front National or other parties expect to repeat with Muslims? Some of the Front National voters undoubtedly do want that, but the program of the party calls for a halt to further immigration and a defense of “secular values.” France already has more police per capita than any other European country. Even so, security lapses allowed the Kouatchis and Coulibaly to escape detection of their plans to kill.
There is going to have to be a third way between “political correctness” and stupidity.
 Two million out of three million in the early 1970s versus two million out of seven-and-a-half million in th early 2000s.
