I am Jewish. I lost family in the Holocaust. I am not angry. The people who killed my family are dead. Taking vengeance on people who had nothing to do with it makes no sense. And even if somehow Israel was doing this in Germany right after the war, it still wouldn’t make it right.
On top of this, there were survivors like Eva Kor who would have entirely condemned this, and rightfully so. Eva Kor forgave Hitler and the Nazis for what they did, which I think is far bigger and better vengeance than anything the people you are, let’s not say defending… explaining? are trying to do.
In my opinion, there is no better revenge against people who tried to dehumanize you and your family than to be the bigger human.
The Torah may repeat Hammurabi’s ‘eye for an eye’ concept, but let’s leave those ancient concepts where they belong along with the superstitious beliefs that went with them.
