Have you read Joan's book?
No, but it clearly centers on an important issue. I guess one of the questions has to be the relationship between 'rule of law' and -- I don't know the term for it -- natural occurrence? Something has to have a 'trump' in these situations, and I would suggest that 'law' is it. The Mandate for Palestine was drawn up in 1920 and became operational in 1923, and yet the State of Israel was not declared until 1948, and only then after some serious terrorist activity on the part of Menachem Begin and Moyshe Dayan. Both Jewish and Arab immigration clearly boomed during the intervening years, as I gather is Joan's argument.
