Just for your information, this chart shows Muslim populations in Europe. I think some of these numbers are a little low - this shows the Netherlands with just 5% Muslim. This was the best quick reference graph I could find, but I think in most cases the number of Muslims is low by about 200,000.

Another source (though I hate PBS and especially Frontline) that has I think better numbers but not the fancy-dancy, quick reference graph:

Frontline gives some background on Al Qaida in some European nations, and you might find some interest. Even though it's Frontline, the info here rings true to what I know to be factual.
6% seems to be the tipping point. As soon as a society is 6% Muslim, they start agitating, hacking heads and demanding independence.
Thanks...I fdon't think europe is sunk, in fact I think events like today will infuriate places like england and the "commoners" will revolts against the militant scuzlims.
