Tom, let me add this thought about complexity and the Israel-Palestine problem:
Before Zionism took hold, there was an indigenous Palestinian Arab Jewish community living with the Arab Muslim and Christian population, and particularly in Jerusalem. The name " Jewish Quarter" in the Old City testifies to that. The Jews of those days spoke Arabic and rubbed shoulders with Christian and Muslim Arab Palestinians. Within the crowded souks of the walled city what I like to think of a peaceful rich social ecosystem developed. There was a dense network of social, economic interaction but not perhaps religious, as each group had their own revered place of worship. There was occasional conflict as would happen in any crowded community, but none of the outright hostility that came later with mono-polar Zionism (their slogan was "A people without a land for a land without a people [sic]" .) The Judaisation of Jerusalem either by forced expulsion, destruction of whole Arab neighbourhoods, or more quietly by laws and other measures designed to make the Palestinian Arabs leave - and which have succeeded to a large measure. So much for the complexity that your Israeli co-author Bar-Yam seems to advocate.
Please pardon the bitter note here and make an effort to learn the facts about Palestine, rather than rely on what Zionist propaganda has so successfully spoon-fed the American people. Einstein's disgust with Zionist terrorism, and his advocating equal rights in Palestine for the Arabs and Jewish communities is one of the reasons why I wrote my essay around Einstein's happy persona.
Best wishes,
