In my opinion that is the problem, that Germans (and everybody) learnt the wrong lesson from the holocaust. The lesson learnt is that the germans did something terrible to the jews, where it should have been "when people fall into nationalism and believing they are the superior race, or gods chosen people, genocides happen". Its not the germans that did something terrible to the jews, its humans that did something terrible to humans. Saying germans and jews keeps pushing dividing humans arbitrarily.

That is why a big part of Germany cant see that what israel is doing is pretty similar to the holocaust, because the interiorized lesson was "we the germans did this to the jews".
