How about a right of return for 900,000 Jews who were expelled or fled Arab countries after '48 in exchange for R of R for Palestinians?
Ah, another provocation. Call it the Zero Option, heh.
Seriously, the most Palestinian diaspora will ever get, though justice would demand that fantasy of a single, bi-national, democratic secular state (marginalizing both the right-wing religious Zionists and the Islamists) be implemented, is a large cash payout to the displaced of the Nabka for property they will never live in again, for land on the West Bank or Gaza in the pre-'67 borders.
In contrast to left-liberal and progressive Jews who talk with and strategize all the time with Palestinian and Arab pragmatists on the Left, I never see the American radical left ala Al-Awda propose a serious solution.Just militant agit-prop.
