Visiting North Korea some years ago, I was lucky to have a fairly genial "minder" whom I'll call Mr. Chae. He guided me patiently around the ruined and starving country, explaining things away by means of a sort of denial mechanism and never seeming to lose interest in the gargantuan monuments to the world's most hysterical and operatic leader-cult. One evening, as we tried to dine on some gristly bits of duck, he mentioned yet another reason why the day should not long be postponed when the whole peninsula was united under the beaming rule of the Dear Leader. The people of South Korea, he pointed out, were becoming mongrelized. They wedded foreigners—even black American soldiers, or so he'd heard to his evident disgust—and were losing their purity and distinction. Not for Mr. Chae the charm of the ethnic mosaic, but rather a rigid and unpolluted uniformity.
