This next quote brings light on the subject on what Germany has been doing scince the Holocoast. "Germany has far more memorials and museums for the former concentration camps, as well as Jewish museums, than other European countries. Much Holocaust education is given in schools and other learning institutions. Conferences and workshops are devoted to the subject to an extent that is nearly unique in Europe. Nevertheless, a clear self-perception prevails of the Germans as victims.
Despite supposedly being taboo, this theme has been one of the dominant narratives among German families since 1945. Starting in the mid-1990s, it was embraced in the political and educational domains as well. But as narratives changed under the impact of historical debates and political developments, some of the German attitudes toward the Holocaust, the war, and issues such as flight and expulsion changed as well"(jcpa.com).
Over time different events have corrupted the view so much that most Germans see themselves as victims of what Hitler did. But the Germans don't want it to happen again, because they teach it in schools and have many memorials around their country.
