Yes, standing with an apartheid state aggressor and occupier (aka Israel) is standing on the wrong side of history. It adds to the irony that Russia is doing the same to Ukraine.
Being Jewish doesn’t mean it’s acceptable to support Israel’s “right to self defence” which doesn’t mean what you may think it means. We discovered (over several decades) that Israel “defending its borders” means killing and oppressing disproportionately more civilians and children than it does killing “terrorists” and keeping Gazans in an open air prison. In essence, every country has the right to self-defence, this statement is true. However, no county has the right to commit one war crime after the other and get away with it.
