In the years after the Six Day War, tens of thousand of Arabs were allowed - and encouraged - to visit Israel. And they did! Arabs even organized tours to Israel!
Which just goes to show that the hate of Israel in the Arab world has been orchestrated by the Arab leaders, and a generation of incitement has had its effect. But if there was true normalization, without the anti-semitism and Israel hatred in the Arab state media, things might be much different.
