Nordic,
I like your gusto, but I think you are wrong.
The object isn't to kill all Muslims, it is to try to get the 90% to become secular, like Christians in the west. When the secularists out number the radicals, then the base for Radicalism will be cut off.
There are some very radical chrisitans out there but I wouldn't put there number past 10% either. The Secular christians and atheist keep them in line.
When the radicals have some thing to lose by War, then War would be a very unlikely outcome.
Poor, disenfrachised, desperate youth will always be willing to sign up for radicalism. You see it in the West with all groups. But in these poor countries these groups of youths are 90% of the population instead of 10% like the west.
Your brits caused your own troubles. Your country let in some of the most militant Muslims to preach at their mosques. These dudes were so bad, they were kicked out of places Egypt, Jordan, Saudi Arabia, and Iran. Now you pay the price of rising Muslim violence. Tell your law makers to kick, those that espose hate, out of your country.
