It's too late now for anything other than a bloody solution to this problem.

Western Europe will see a complete breakdown of law and order within 15 years, and very likely a REAL fascist leader will emerge to lead a genocide of Muslims.

Western leaders failed us badly here. If they addressed this years ago then it wouldn't end in a violent way.
