The Palestinians reaction to the American Peace proposal shows an unwillingness to accept a Jewish state within ANY borders.
This, not the "occupation", and not the "settlements" is the main obstacle to peace in the region.
When they chant "From the River to the Sea", this is what they mean.
Hassan Fouda of Berkeley's comically named Jewish Voice for Peace also rejects any plan that doesn't create a Palestinian state from the "river to the sea"
The newly proposed peace plan should open the door and provide an opportunity for both sides to return to the negotiating table. Both Palestinians and Israelis should embrace it as a chance to move closer to peace and to resume negotiations after a long hiatus.
Comprehensive peace proposals were presented to Palestinian leadership three times in the past – once by the United Nations (1947) and twice by Israel (2000, 2008). All three times Palestinian leadership rejected broad peace deals, while Israel said yes.
Palestinian rejection – anchored in refusal to accept the right of Israel to exist as a Jewish state remains the primary obstacle to peace.
