Islam wishes to establish a worldwide caliphate and is doing so at an alarming rate. The mass migration of Muslims to Western European countries is an invasion. The goal is to populate and eventually take political control of these countries. Such control will establish these countries under a caliphate; once established, Sharia law will be imposed.
Is this analysis far-fetched? I spent many hours in the 1980s discussing Islam and Christianity with a Saudi acquaintance, who was educated at a Jesuit university in America. He predicted precisely what is happening today. He stated that as this process occurs, we might meet again; unless I was willing to convert to Islam, it would be his duty to kill me as an infidel.
He was serious. He was not being manipulated. Rather, as he said, "This is the teaching of my faith, a teaching I take literally, and when the time comes, will live out."
