Had the article been about boxers who died or survived the Shoah, and they only mentioned Victor, yes, it would have been a "pity", as you put it. Read the article carefully, it is about Tunisian Jewry, and more generally, the North African experience with the Shoah. Krieger, if I am not mistaken was Eastern European. Why then is it a pity he was not mentioned? Surely you're capable of noting and differentiating this, yes?
In fact, your comment somewhat demonstrates an issue, the Tunisian Jewish experience has not quite received its due mention. Unless your one who believes it was uniquely Ashkenazi experience.
For the record, I'm half Tunisian Jewish and half Polish Jewish, the shoah affected both sides, but we should give due respect to the Tunisian experience as well.
I wish you a good day.
