Hmmm. Unless they can find a RELIABLE way to tell the terrorists/fundamentalists from the every day Abdul-schmuck, they're going to have to.
Unfortunately it's not that easy for them anymore. During the Battle of Tours and the Reconquista it was easy. The Muslims weren't citizens of the respective countries and they most certainly weren't citizens with special rights under the law.
Personally, I think that Europe's slit their throat through multiculturism. As Mark Steyn put it so eloquently, they're "sleepwalking their way to suicide".
Always remember the 25% solution for muslims. At 25% of the population, they'll begin agitating for either autonomous areas or outright take over and imposition of Sharia law.
Belgium, Holland and France are beginning to have their their eyes opened to what kind of people their dealing with, but it's too late. I understand that in the housing projects around Paris, there are almost a million Muslims of Algerian/Morrocan descent and they hate France, not on religious grounds necessarily, but simply because it's France. They even boo'd the La Marsilles, Frances national Anthem during the World Cup soccer match between France and Algeria a year back.
Sorry. I'm rambling maybe. I guess my premise is that even if Europe has the will to eject the most hatefull fundamentalists, I don't think it's nearly so cut and dried as just saying it. And Im not sure that they're going to have the will until they get a 911 handed to them.
Godspeed
