It will be because our countries are entangled in a war with an enemy that cannot be stopped by occupying their countries. At the same time, it will also be because we have become soft in the face of genuine threats; the West does nothing in preventing the rise in numbers of nuclear states.
It will be because of insidious multiculturalism, where we will give not only acceptance but also subsidize ideas that run counter to the ideals of individual rights and free enterprise.
