countess in brief it is a plan to bring into Europe many people from different countries and encourage them to breed with Europeans and in the future make a race of mixed parentage. an excerpt from Wiki may explain better:
The man of the future will be of mixed race. Today's races and classes will gradually disappear owing to the vanishing of space, time, and prejudice. The Eurasian-Negroid race of the future, similar in its appearance to the Ancient Egyptians, will replace the diversity of peoples with a diversity of individuals.
Instead of destroying European Jewry, Europe, against its own will, refined and educated this people into a future leader-nation through this artificial selection process. No wonder that this people, that escaped Ghetto-Prison, developed into a spiritual nobility of Europe. Therefore a gracious Providence provided Europe with a new race of nobility by the Grace of Spirit. This happened at the moment when Europe's feudal aristocracy became dilapidated, and thanks to Jewish emancipation.
