European Royals and old money families have been running short on cash since the rise of democracy. Importing Muslims en masse helps with keeping the natives poor and also helps line their pockets as the influx on Muslims was part of a deal with the Saudis and Qataris. The Islamic Royals essentially paid our Royals and US WASPS to turn a blind eye and assist with the Islamic importation.

e.g. Belgium

In 1967, King Baudouin lent the building to King Faisal ibn Abd al-Aziz of Saudi Arabia with a 99-year rent-free lease, on an official visit to Belgium as part of negotiations to secure oil contracts.[4] The building was turned into a place of worship for the use of Muslim immigrants to Belgium, who at the time were notably from Morocco and Turkey.[5] As part of the deal, imams from the Gulf area would be hired, although their orthodox salafism was a tradition, according to Georges Dallemagne, different from that of the more open-minded immigrants[5] but their teachings would over time turn them into a more orthodox tradition and imams would discourage immigrants from integrating into the Belgian society, according to Georges Dallemagne.[5] The mosque, after a long reconstruction carried out at the expense of Saudi Arabia by Tunisian architect Mongi Boubaker, was inaugurated in 1978 in the presence of Khalid ibn Abd al-Aziz and Baudouin.[6]
