The most successful immigrant group in the history of the world is American Jews. Why? Because they integrated enthusiastically into the mainstream of American society. They rejected the ghetto and embraced American pluralism. In Europe, this same eagerness to belong, to contribute, and to thrive – and not remain segregated and ghettoized – led to the Jews’ near-extermination. It seems to me that part of the reason why anti-Semitism is so widespread in Europe while Islam is often treated with kid gloves is that the European elite has a reflexive contempt for a group that blends in and a reflexive respect for a group that holds itself proudly apart and resists assimilation. That’s a formula for disaster.
