I too can't see any particular reason to apologise to the individual. He giot a good storyn out of it, and it has probably helped his career, and he didn't suffer any harm whatsoever.   If that's the worst insult he's ever had he must have led a pretty sheltered life, which I somehow doubt.

Nor can I see how there is any insult implied towards Jews in generral, or towards the man himself, as a Jew. It'd make sense for Livingstine to say that, since some people seem to have taken it that way.

It's true enough he said "German" where "Nazi" would have been been more appropriate. I suppose logically be argued that most concentration camp guards in the War in fact weren't Nazis - but then many of them weren't German either. However given that the Nazis were in charge of it all that woudl have been a more appropriate term.

And since todays's German can't fairly be seen as carrying any blame for what their fathers (and in more cases their grandfathers) did, an expression of regret for that would make sense as well.
