It was newly formed Arab countries' unjustified joint decision to destroy Israel in the middle of the 20th century, which led to this point, people somehow forget who started it all.
Again, none of that, to me, vitiates the right of an Israeli person to live peacefully in Israel, but I don't take kindly to anyone's nationalist fantasy, and I find it absurd that people continue to trade in the kind of simplistic tribal patriotism that just regurgitates their ethnic narrative.
