Democide is the term I think you’re really looking for, and there was plenty of it prior to WWII. Ask the Ukrainians about the Holodomor, for one example. Look into what King Leopold II did in the Congo.

No, not really because I very much doubt that the government will do anything about the Muslim problem.
I believe if anything is to be done to save Europe it will rise up out of the common people and it will be cruel, bloody and ugly.
If it doesn’t happen that way I really believe that Christian Europe will be history because the governments of Europe are ossified in their ideology and incapable of saving themselves.
