This is quite a long article in Opinionjournal that took a full cup of coffee to completely digest--I feel like I've been on a "nine-countries-in-four-days" tour. Steyn takes on everything from political correctness to birthrates to the fall of civilization, but somehow makes sense of it.
Most people reading this have strong stomachs, so let me lay it out as baldly as I can: Much of what we loosely call the Western world will not survive this century, and much of it will effectively disappear within our lifetimes, including many if not most Western European countries. There'll probably still be a geographical area on the map marked as Italy or the Netherlands--probably--just as in Istanbul there's still a building called St. Sophia's Cathedral. But it's not a cathedral; it's merely a designation for a piece of real estate. Likewise, Italy and the Netherlands will merely be designations for real estate. The challenge for those who reckon Western civilization is on balance better than the alternatives is to figure out a way to save at least some parts of the West.
