Isalm & the West: Co-Exist?

http://www.breitbart.com/Big-Peace/2013/11/17/6-contractors-found-beheaded-in-Afghanistan Is there a future where Islam and the West coexist peacefully & productively? I'm not an expert on Islam; I'm an interested amateur. But the people I know who have studied the issue, Christian scholars of religion who have lived in (& been educated in) the Middle East & Europe, are incredibly negative about the future of relations between Islam & the West. They tell me that Islam as predominantly practiced in Europe & the Middle East today is ascendent & aggressive, and has no interest in peacefully coexisting with the post-Christian pluralistic West.
