As I understand it the peace proposal of 2000 gave the Palestinians only 66% of the West Bank, with those displaced previously thus being deprived of the property from which they had been displaced.
Other proposals have been of the same sort, and I do not see how the Palestinian Authority could accept such an agreement in a way that is in accordance with their duty to those displaced.
"Israel would retain around 9% in the West Bank in exchange for 1% of land within the Green Line."

The issue for the Palestinians is way way deeper than 9% of the 67 lines. Hammas doesn't hide its will to turn Israel proper into an Islamic state. PLO never actually forfeited the right of return which is considered a "sacred" right. If only the issue was as simple as offering 9% more percent.
I very strongly dislike Islam, but to say that Israel has done as it has due to the Muslims seems difficult to support, since Christian Palestinians do exist, even if they're few and have been treated in the precise same way as the Muslims despite their lack of association with terrorism etcetera.
