@Moment-in-Time,
That's the main point I wanted to say with my above response, MIT: German Holocaust survivors live here, tour through schools to tell pupils about what happened, guide groups through the concentration camps.
Second and third generation American Jews, whose parents/grandparents came from Germany, come quite often over here visiting here ancestors' native country. (My mother's Jewish school friend wanted to come for a graduation anniversary years ago, but died weeks before.)
