Why import foreigners in the first place you dummy?
Because the U.N. demands you ruin your country.
Simply declare war on the U.N.
Germany is setting up for another Hitler.
That was precisely why it was decided to flood Germany with immigrants after the war. The thought being that it would never be possible for another Hitler to rise to power. Jews in pre-war Germany were a relatively small portion of the German population.
In the 1970's the Germans started importing Gastarbeiter (guest workers), mostly from Turkey. Turks were the butt of jokes, sort of like Pollack jokes in the United States. They were seen as sort of hapless, and they were not considered permanent residents, merely guests, who were expected to return to their home countries. Eventually, they brought their families along, their kids went to school in Germany and felt that they were Germans.
