It's already taken hold in countries spanning a very large number of people. It matters in Pakistan for example. Pakistan has nukes. There's a threat there to everyone.
Sorry, I suppose I wasn't very clear. I was referring to the fear some people have of Sharia law taking hold in the U.S., not in other countries, which is a baseless fear that can be used by those in power to manipulate those who are afraid. The fear of fundamentalism in other countries is not so baseless, but it can still be used to manipulate people if those people don't examine the relationship between their fears and the policies advocated in their name (ie. fear of fundamentalism justifying not just surveillance of fundamentalists but of everybody).
