Many Jews, myself included, have positive experience with Arabs and even Arab friends. That seems to imply that Arabs are generally good and peaceful relations with them can be established. But recall that anti-Semites dispel criticism with “I have a Jewish friend” mantra. On the micro-level, an Arab taxi driver or bread seller is decent, hardworking person. He wants to earn money and is nice to Jewish customers. His immediate inclination is to serve Jews, not kill them. Complex systems do not equal the sum of their parts and nations behave differently from individuals. Ideology cements nations, and they are concerned with ideology more than well-being. Palestinian Arab community does not want to sell more pita bread to Jews, but realize Palestinian aspirations by destroying a Zionist state. Zhabotinsky accepted Arabs in Jewish state, presuming they would follow individual interest. Since then, Palestinian Arabs developed national backbone, and Israel failed to destroy it from village bosses up. Israel lost an ephemeral chance of coexisting with individual Arabs, and has to fight an Arab nation.
