The memorial, the first public service at the site for as long as anyone can remember, was organized by the Association of Jewish Soldiers, a small but growing group in the German military whose existence testifies to the feeling by at least some Jews that it is possible for them to be patriots again in the nation that once tried to wipe them out.
If you're interested, there's more information (in German) on the Bund jüdischer Soldaten at their website.
One striking quote:
Abraham Ben, the son of a concentration camp survivor who has helped organize similar events in Munich, said that he saw no problem with Jews serving in the modern German army.
“Ten years ago I would have given you a different answer,” he said.
But, he said, “Jews in Germany are no longer sitting around with their bags packed. This is home.”
In a different context, I wrote about related matters.
And about other soldiers.
