This raises the fascinating (for historians 500 years from now) but disturbing (for those of us in the here and now) question of whether a bunch of Turks, Moroccans, Indonesians and Africans can get along in Amsterdam without the presence of any Dutch. Even apart from the Eurabia thesis, the tremendous diversity in these cities, which may not even include in any great numbers the people whose ancestors created the famous Dutch tolerance to begin with, is to put it mildly a problem in its own right.
With the actual immigrants, and their children, it seems that the integration's machinery is broken. They keep a strong links with their original countries (via satelite TVs, internet, summer holidays in Algeria or Morocco...) and, a part of them tend to partly or totally reject the french and european values. And that is really alarming.
