Stop them before become majority in all European countries..Than they'll try to use european laws to create their state and independence
Too late for that. Western Europe is already lost. Most of the Western European nations will become Muslim majority in a few decades time (perhaps with the exception of Italy). Eastern Europe is the only hope (Poland, Belarus, Slovakia, Hungary.etc). Even if there is zero immigration from now onward, the already existing Muslim population will start multiplying at a rapid pace to drown the natives in the Western European nations.
Mother russia and putin will save us all for sure.
