In America, we learn that Hitler and the Nazis committed the Holocaust; in Germany, German children learn that they all participated in it, because the Germans came to believe that acknowledging their collective culpability as individuals was the only way to prevent it from ever happening again.
Americans, meanwhile, continue to debate whether the Civil War was fought to preserve the institution of slavery, as stated by actual Confederates at the time, or to settle a far more abstract and nebulous quarrel over the less morally indefensible concept of “states rights.” History isn’t always written by the victors, especially if there’s a version that makes everyone feel a little less guilty.
