There is a mass migration from Islamic lands to Kafir lands. It is the mission of Islam to bring the Sharia into power, everywhere. There is an ethical divide between Islam and the hated Kafir civilization. It is the purpose of Sharia to dominate the Kafir civilization.
As Muslims immigrate, they immediately make Sharia demands. These demands are endless in details, but the process can take generations. We can see the centuries long transformation in the Middle East and Turkey which used to be Christian.
This does not mean that every Muslim takes part in the politics of Sharia, since only a few Islamic leaders are needed. The reason that Islam can win every attempt to advance Sharia is that Kafirs are tolerant of all demands and do not push back. So if our attitudes do not change, Kafir nations will become Sharia nations.
