Sharon's successor - Ehud Olmert - had neither forgotten nor overlooked the critical significance of Bush's commitments when
agreeing to resume negotiations with the Palestinian Authority - telling an international audience of world leaders at Annapolis on 27 November 2007:
"The negotiations will be based on previous agreements between us, U.N. Security Council Resolutions 242 and 338, the road map and the April 14, 2004 letter of President Bush to the Prime Minister of Israel."
Gaza by then had become a de facto terrorist State with Hamas firmly entrenched as Gaza's governing authority.
Israel had since its disengagement been subjected to a sustained barrage of thousands of rockets and mortars fired indiscriminately into Israeli population centres from Gaza by a bewildering variety of terrorist groups and sub-groups who would have had no chance of operating so freely from Gaza if the Israeli Army had remained there.
President Obama's attempt to disavow Bush's commitments was first orchestrated by then Secretary of State Hillary Clinton - as
this report on 6 June 2009 disclosed:
"Since coming to office in January, President Barack Obama has repeatedly called on Israel to halt all settlement activity in Palestinian areas, a demand rejected by the government of Israeli Prime Minister Benjamin Netanyahu.
The Israelis say they received commitments from the previous US administration of President George W. Bush permitting some growth in existing settlements.
They say the US position was laid out in a 2004 letter from Bush to then Israeli premier Ariel Sharon."
Clinton rejected that claim,
saying any such US stance was informal and
"did not become part of the official position of the United States government."
Clinton--doubling again as Obama's attack dog--made Obama's intentions
clearer on 25 November 2009:
"We believe that through good-faith negotiations the parties can mutually agree on an outcome which ends the conflict and reconciles the Palestinian goal of an independent and viable state based on the 1967 lines, with agreed swaps, and the Israeli goal of a Jewish state with secure and recognized borders that reflect subsequent developments and meet Israeli security requirements."
