A nation in which several cultures enjoy an equal status ceases to be a nation. It becomes a “United Nations,” a forum where bureaucrats representing various cultures squabble with each other. History tells us that the United Nations type of nations do not survive. There have been several empires that were multicultural—for instance, the Roman Empire and the British Empire. But first, an empire is not the same thing as a nation; second, the Romans and the British could keep their empires together only so long as their own culture was strong. Once their own culture weakened, the Roman and the British empires were finished.
