We cannot deal with them on the same basis and in the same terms we do with other nations or cultures. If we deal with them at all, it needs to be at arm’s lenght and they need to be kept isolated.
That is exactly what we’ve done in the past (deal with the Islamic world as “The Other). This is wrong, as it only provides more ammo for the radicals to show the it’s “Us against Them”. Besides the world has become to small and interconnected place to allow such a large part of humanity to live in a cultural black hole. (See Tom Barnetts “The Pentagon’s New Map”)
We've always been willing to deal with any nation or culture on equal terms, as long as they were willing to.
