A provocative study of German peace of mind For the first time since the end of the exhibition 'War of Destruction. Crimes of the Wehrmacht 1941 to 1944' Hannes Heer spoke about the background to the campaign against the show, which he directed. She had questioned the legend of the clean Wehrmacht, and the shock was correspondingly great. The attempts to defame the exhibition were successful after four years. It was withdrawn and replaced with a new, completely defused version. The war and its crimes have again become the work of a few specialists.
