So far, the Palestinians (some Palestinians) have offered Israel the land inside the green line in a peace deal.
Israel has never accepted the offer.
West bank was given toIsrael by jordan. There was an expectation of a land swap so settlement and land behind the wall would remain as part of Israel, and land would be added to gaza or to northern WB of equal size, or close to.
Ranting about building more units on land that west of the wall just for the sake of being troublesome is not worth the effort. I don't think settlements should be built east of the wall, but if there is a need for security, roads, infrastructure etc. to be built, Israel should do so in areas that are still under it's jurisdiction.
If Israel develops the land that will be turned over to the PA, it simply adds to the value.
PA should be building jobs and developing their own towns not complaining about Israel.
You want to talk to Israel? OK, but stop the whining and actually put forward some compromise, give Israel something and Israel will in return offer something back till you find some middle ground that both can live with. Don't put a list of demands on the table, deal with each issue point by point. Expect that you will not get everything nor will the other party, but you find what is best for both sides.
