What if in the year 2000, Yasir Arafat accepted the Israeli offer to withdraw 100 % from Gaza and 95 % from the West Bank.
These are big misconceptions. What Arafat was offered at Camp David by Barak and Bill Clinton was nothing close to this. What was offered was:
- Full withdrawal from Gaza
- 91% of the West Bank, with Israelis annexation big chunks of territory east of Jerusalem and in the Northern West Bank around Ariel.
- A symbolic "1% land-swap" of unspecified territory.
No actual map was produced - just this as a basis for discussion. Israel would also have maintained control of all of Palestine's borders and airspace, and would have had control of a long corridor of territory east of Jerusalem with the authority to cut off traffic between the northern and southern West Bank for security reasons.
Finally, regarding Jerusalem, Barak was willing to grant a few Arab neighborhoods in East Jerusalem, along with (more generously) split sovereignty over the Old City and some kind of sovereign division of the Temple Mount.
NO Palestinian leader, even one considerably better than Arafat, could have accepted these provisions.
Israeli negotiators DID make a more generous offer in January of 2001 at the Taba negotiations, where they did put forth something more similar to what you described - a 5-6% annexation plus a 2-3% landswap, so something approximating 97% of the West Bank. But talks at that point ran out of time and were called off due to the impending Israeli PM election which Sharon won.
