He was formerly the head of the Russian agency in charge of foreign migrants speaking in an interview with the BBC. He said that Russia needed more Slavs and wanted to make sure that the mixing of the races occurred in the right way here and not in the messy fashion that it did in the rest of Europe. He was aware of the ethnic tensions created by Central Asians and dark-skinned Russians.
This is a tension not new in Europe. In the early 30’s National Socialist(Nazi) Propaganda Minister Dr. Joseph Goebbels gave lectures at an exhibit about German womanhood that discussed how the white Aryan race was dying out. He said that in the present economic crisis women had taken too many jobs. They ought to be allowed to stay home to propagate the race. Their sons would help the government defend German borders against the Eastern threat.
Ironically the hordes that Dr. Goebbels hoped to fight were the Russians.
