During the peak of the refugee crisis in Europe, which is still going on, by the way, I referred to the refugees as Muslim light infantry. After all, the "refugees" are nearly all young men of military age. Near the end of the excellent book, The Strange Death of Europe, the author notes that Saudi Arabia did not bring in a single Syrian refugee to convert them into a Saudi citizen as the Europeans were doing. They did, however, build over 100 mosques in Germany.
Hey, if the infantry is going to be there, they might as well be on your team. Go Wahhabis!
