The picture aint that rosy. Large scale massacres in some places is possible. Also many muslims in these lands are going very far from deen and zina and drugs is a major problem. Inshallah I pray what is written does come to pass but I'm not too optimistic. In the whole of the western world the UK has the strongest muslim community in many ways (not population wise as France etc has larger numbers) but we have had almost zilch impact on the local population. This is something to really think about.
