It is part of the Arab Initiative. That Initiative embraced Resolution 242 and 238 which allows for negotiated land swaps. The swaps though are not compulsory. They are subject to Palestinian approval and agreement since it is their territory and not Israels. Israels only legitimate borders are its 1948 ones. If Israel does not sort itself out it could be made by UN and ICC to return to its 1948 Borders. Those citizens outside of those borders would become Palestinians just like under the Partition Plan.
