from an article posted by the Jerusalem Fund:
There is a way out for Abbas - and the Palestinian people - of the trap of endless negotiations as the ground is pulled out from under their feet: To work for an end to the occupation before going into negotiations. What would this involve? The Palestinians would state that they are committed to living in peace and security with Israel, but will not negotiate until it withdraws its soldiers and settlers from the occupied territories, finally applying the principle that underpins United Nations Security Council resolution 242 of 1967 - "the inadmissibility of the acquisition of territory by war."
Thereafter, Palestinians and Israelis would negotiate final status issues, including a just resolution for Palestinian refugees, security and water. International peacekeepers would be placed between the two sides, including around Gaza, to maintain security for both sides until a final status agreement is signed.
This approach is gaining strength with Palestinian analysts. Amman-based analyst Mouin Rabbani recently wrote for the congressional newspaper The Hill that Palestinians should "agree to negotiate only the mechanisms of a permanent end to the Israeli occupation" before turning to final status issues. Ramallah-based businessman Sam Bahour, who blogs at e-palestine, says that trying to solve final-status issues "while the boot of occupation is still on our necks is hallucination at best and a crime at worst."
