Have we come, at last, to the end of morally instructive Nazis? After eight decades, Nazis may seem to have retreated into a class with orcs and cable-TV sharks, fantastic creatures representing evil, rather than historical figures who actually were evil. It is fine to say we should look past the History Channel Nazis—“Hitler and the Occult”—to the real thing, but there comes a time when the iconic imagination really does overwhelm the historical imagination. No one any longer objects to jokes about the Spanish Inquisition, which burned skeptics and Jews alive, but which exists now first of all as a Monty Python sketch (“Nobody expects the Spanish Inquisition!”), while Henry VIII and the Tudors, who burned men, too, and brutalized thousands, are a soap opera before they are a sermon.
