I'm still working on the next chapter of my Psychological History of Palestinian Arabs, but I just stumbled on an article in the Palestine Post from August, 1948 that fits in nicely with my last part about the Arabs of Abu Ghosh.
The Bedouin village of Tuba cast their lot with the Zionists in the 1948 war (as well as during the 1936 Arab riots.) This further proves that the Palestinian Arabs at that point in history were far from unified, and it proves as well that the Zionist were not interested in "ethnic cleansing" but in having Arab citizens who wanted to live in peace.
