I know you're Jewish and have ties to Israel, so I understand your prospective.
Yeah, FWIW, in that post, I explicitly said that the Palestinians need the living space in the Jordan Valley more than the Israelis need it. Honestly, I'd be quite content to settle for something like the 2003 Geneva Initiative, but slightly more in favor of Israel (though with larger territorial compensation in Gaza to the Palestinians to compensate for this). This is the best shot at a fair settlement, honestly, and I think that the region has suffered enough bloodshed already. Would have been better to make such a peace 20 years ago, but better late than never.
FWIW, if it wasn't for the Nazis and them driving a lot of Jews to Palestine, I'd actually be rather ambivalent about Israel's creation and think that the Palestinian Arabs should be entitled to all of Palestine. But creating a Jewish state elsewhere, such as in Eastern Europe, would have simply left it exposed to the Nazis, and by 1947 there was already a large Jewish community in Palestine. So, I think that a peace based on the 1967 lines, but with mutually agreed land swaps as per the 2003 Geneva Initiative, is the best possible deal right now. FWIW, I actually view this as an Israeli concession since as I previously said, the Arab countries who fought Israel in 1948-1949 insisted that Israel's new borders be viewed as provisional rather than as permanent.
