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.
