...Amidst worsening economic trends and increasing instability, more and more educated young people will seek their futures in more promising countries— hastening the dissolution of the old society...

...For children of immigrants, who have no strong attachments either to their old or new countries, extremist ideology often fills the void...

...Bicultural societies are rarely stable...

...Would France help us thwart the nuclear plans of the mullahs in Tehran...

...In many Muslim countries, people may think about their own future more soberly or reasonably, because they're not viewing things through the perspective of mounting conflict with hedonists across town...

...If there's another side of us that is fascinated by disaster, there are lots of disaster stories competing for attention...

...The utter incapacity of international institutions will discourage smaller countries from thinking about anything more than their own immediate interests...

...European birthrates have fallen way below replacement levels...

...So Steyn foresees "societal collapse, fascist revivalism, and then the long Eurabian night, not over the entire Continent but over significant parts of it...

...Why Constitutional Government Requires Sovereign States (Princeton...

...The threat is not that a new caliphate will rule the world, but that the world will revert to medieval chaos and wretchedness...

...Elsewhere, there may be resistance, triggering street violence or political upheaval...

...Maybe...

...A reform of Islam...

...But I'm not sure invoking the imperatives of national defense in every debate about domestic spending or regulation is really a good way to get people to take defense concerns more seriously...

...Complacent talk of multiculturalism has allowed European governments to ignore the challenge of winning the loyalties and attachments of immigrants...

...A calm and reasonable future is not, after all, guaranteed by the advance of technology, by the expansion of trade, or by the softening of old ideologies in the advanced countries...

...The challenge starts with demographic trends...

...Even if that nightmarish vision is too extreme, the strategic point remains: No matter what rhetoric our State Department adopts, European nations are not going to be confident, capable partners for American international aims...

...But restless young people may well combine the worst aspects of Western decadence with the worst impulses of Islamist extremism: "Whether in turbans or gangsta threads, just as Communism was in its day, so Islam is today's identity of choice for the world's disaffected...

...In practice, Steyn warns, Europe is trending toward societies that are not so much multicultural as bicultural—split between a growing minority that embraces Muslim discipline and identity, and a bewildered, anxious, aging population that does not...

...We may find unexpected allies, including some in those Muslim countries that don't want to be dominated by jihadist visions...

...In today's Italy, for example, there are barely half as many children under the age of five as there were in 1970...

...What do you call a jurisdiction split between post-Christian secular gay potheads and anti-whoring anti-sodomite anti-everything-you-dig Islamists...
