Interesting article.
The world is getting grayer. Or at least the developed world. Looking at history, this is where the barbarians invade. When Rome fell in the West, it did so because Romans stopped making more Romans. They had to import workers and soldiers from beyond her borders to do the jobs that Romans wouldn’t do. You ended up with a large portion of the military being non Roman, with non Roman ideas of power and loyalty.
The US will become more and more Hispanic. But Europe is becoming islamic. Our children will face a time where St Peter’s and Augsburg are totally filled with muslims.
Even Biblical history reveals that whenever a nation turns it's back on God, (as the USA has been doing in increments for years now), those nations are always invaded by barbarians, and not necessarily identified as so until it's too late. That is where we are now and headed even moreso under this administration who has an open door policy now in place.... Obamas recent visa changes have ended any hope we have of curtailing the invasion of our country.
