FILE - In this Thursday, April 12, 2012 photo, tourists stand around the sculpture 'Mother with her Dead Son' by artist Kaethe Kollwitz at the Neue Wache (New Guard House) in Berlin.

But over the decades, Germans’ attitudes toward the war have evolved from a sense of defeat to something far more complex. (AP Photo/Markus Schreiber, file)
