Interesting part of history there and I've read about many valiant German veterans who were Jewish did give it their all and more in World War I. I think in some ways, the Kaiser for all of his faults did have some forward thinking where basically he didn't care where you came from, who you were or how you worshipped God as long as you were loyal to Germany. I've seen an American plane with an Indian Chiefs head embossed on it with a small swastika on the headress.
During World War One, Germany lionized its Jewish war heroes on equal footing with its Christian war heroes.
This included the award of the "Pour le Merite" (The Blue Max), Germany's equivalent to the Medal of Honor, and the featuring of Jewish war heroes on Sanke Cards that were the World War One German equivalent of American baseball cards.
Below are photos of Pour le Merite winner, Jewish German Ace, Wilhelm Frankl, wearing the Blue Max and featured on a Sanke Card entitled, "Our most successful flyer, Lieutenant Frankl."
