There are too many glittering generalities about this issue. Obviously there is some problem about some Arabs who live in Israel. There is a denial by some Israelis who believe that Palestinians are Arabs and not Palestinians. There is a problem also with Jews who live in Arab countries as well.

This everybody-gets-along-so-well idea is reminiscent of the patronizing attitude of
white landholders in Antebellum and recent US South toward Black people.

Of course there is a problem otherwise there would not be the conflict.

Harvard studies are cheap, these days.
