That being said once the Arabs have done their work they would be deported to the Middle East because they are inferior to Germans.
There is no way the Bank of International Settlements in Switzerland and the Bank of England will allow Arab Muslims, who generally posses the temperament and spiritual disposition slightly more "civilized" and "rational" than a dog with rabies, to permanently amass around their very entities.
There is something called MERS-CoV that's a beta test since 2012, and it will be used to thin the Arab Muslim herd, after they've done their job of eradicating white people and what little is left of Christendom following their orchestrated invasion of Europe and white abortions, contraception, miscegenation, etc.
Even the so-called "moderate" Arab Muslims (who conveniently look the other way and never speak out when a Christian is being killed or raped) will not be allowed to permanently establish large communities around the Jєωιѕн Money Changers. These Arab Muslims are very useful tools but once they've outlived their usefulness in Europe, they will be culled.
