It's not inaccurate to say that Sharon intends to wall in the remaining Palestinian land (about 12% of what the British granted in 1948).

This wall snakes through the area to the east of Israel's border in order to 1) protect the settlements and 2) to thwart any growth (economic, military) of the burgeoning Palesinian population.

This is not unlike what happened in Texas. Lucas Alaman, the Mexican secretary of state said "Where others send invading armies, [the Americans] send their colonists".

According to historian Benny Morris (and declassified IDF documents) Operation Hiram was an intentional 'cleansing' (official document word) of the 700,000 palestinians in 1947 (using methods involving rape and murder) in order to establish the Israeli state. This was up to a point condoned by Ben-Gurion who lost his stomach to complete the job. As much as it pains me to say this, Morris has stated in a Ha'aretz interview that it is only a question of time until all the Palestinians are removed from the land; that this would be the logical extension of what was begun in 1947 and the only way for the Israeli state to survive.
