"Prime Minister Ariel Sharon says Israel may move on its own to evacuate
most of the Jewish settlements in Gaza and some in the West Bank while
simultaneously strengthening its hold on other West Bank settlements.
This move toward disengagement, implemented along with the construction
of Israel’s so-called security barrier, would hasten the separation of
Palestinians and Israelis outside the context of a negotiated
agreement... In a December 18  speech in Herzliya, Israel, Sharon gave the basic outlines of the plan."
Daniel Sobelman, a former Ha'aretz Arab affairs and Middle East correspondent, in an article posted on the Friedrich-Ebert-Stiftung (FES) Foundation website titled "Sharon's Disengagement Plan – First or Final Step?" (accessed May 11, 2005) wrote:
"At the beginning of 2004, nearly three and a half years into the current violent confrontation between Israel and the Palestinian Authority (PA), Israeli Prime Minister Ariel Sharon formally declared that he was presenting, and would lead, a unilateral plan of disengagement from the entire Gaza Strip and from some settlements in the northern West Bank...
The disengagement plan continues to be shrouded in some ongoing vagueness. The exact time table for the withdrawal remains unclear, with Sharon revealing – even to his own ministers – only 'one card' at a time... The government of Israel voted in favor of the current  'revised' disengagement plan in principal on June 6, while...asserting that by so doing it does not yet empower the government to actually relocate settlements.
At the end of August Sharon outlined the tentative time table for his plan. The prime minister has pledged to bring the [settler] compensation bill for formal authorization by the cabinet by October 24. The Knesset will vote on the bill by November 3. Sharon did not designate the exact schedule for the physical evacuation of the settlements, although he has mentioned the end of 2005 as the final implementation date."
