All nations modify their history. Disaster are refined as victores. Bitter turns to sweet. The British turned the painful retreat from Dunkirt into a triumph of the spirit. The Japaneses are much like other people when it comes to dealing with their past. Japan's ruthless invasion of Chhina,for example, is described as "an advance into China". Most offensive incident are also wholly ignored,perhaps hoping that not discussing the unpleasant will somehow make it disappear.
