Pat Buchanan explains that our native born are dying out and that ISIS believes that mass migration into the west is a winning strategy.
ISIS believes it can gradually drive the West out of the Middle East, as it has already helped to drive the Christians out.
Then, ISIS believes, through mass Muslim migration into a West whose native-born are dying out, Muslims can reoccupy these lands they had almost wholly conquered, until stopped by Charles Martel 14 centuries ago.
For some few Muslims, as we saw at Fort Hood, San Bernardino and Orlando, ISIS offers a dream worth dying for. And as they kill and die for ISIS, they will push America where they are pushing Europe—to the right.
