The previous mayor of Barcelona, Ada Colau, ended their status as sister city with Tel Aviv over the systematic crimes from the state of Israel against Palestinians. The immediate reaction of the Israeli embassy was denouncing her as antisemitic, both in the media and in courts, which recently found her innocent.
The position that denouncing Israeli crimes is antisemitic has been the official position of Israel for decades, and that’s a very dangerous game for the well-being of Jews in a world where actual nazis are slowly gaining power, because once you’re run the term down through the ground, calling actual hate crimes against Jews “antisemitic” will no longer have any meaning.
