Yes.
It's a new form of asymmetric warfare.
Islamists had planned the invasion of Europe using this method for decades - and the people who orchestrated the 'refugee' crisis achieved what armored divisions could not - and Europe is being conquered from within.
Now, those same orchestrators are doing the same thing with these waves of Trojan Horse 'migrants' to invade this country and plunder it and outbreed the people in it - for takeover and subjugation to the totalitarian ideals intended for the West.
Read Camp of the Saints to get an idea of what is going on. The author details the overthrow and plunder of Western civilization via this new form of asymmetric warfare. It's a near-prophetic fiction published in 1971 of what is taking place now verbatim. Here's a tiny portion of the plot synopsis:
The migrants make their way north, having no desire to assimilate to French culture, but continuing to demand a First World standard of living, even as they flout laws, do not produce, and murder French citizens, such as factory bosses and shopkeepers, as well as the ordinary people who do not welcome them. They are also joined by the immigrants who already reside in Europe, as well as various left-wing and anarchist groups. Across the West, more and more migrants arrive and have children, rapidly growing to outnumber whites. In a matter of months, the white West has been overrun and the pro-immigrant governments are established, while the white people are ordered to share their houses and flats with the immigrants.
