I have mentioned this before. Many studies have shown that children of Muslim immigrants are, in general, more radical than there parents. So there is NO WAY this situation is going to get better over time.
For the interested, heres info on one such study:

It can get better, but are the European people willing to do what their forebears did to make it better, including forcible conversions back to Christianity and killing them if any evidence was given they were still trying to be Muslim?
