We can conquer them and make them stay in their nations. They will not speak our languages, will not have our names, will not follow our religion and traditions. I don't want to Europeanize them. So they can be who they are and follow their own traditions and religions. We'll control them in their lands. We are going to be their elites. We'll keep their numbers in check and make them stay where they are so we won't have to face this immigration problem ever again.
