Israel accepted borders as defined in Resolution 181. The borders for a Palestinian State are contained in the same document. Israels borders were never temporary so no need for or requirement for Palestines borders to be temporary. Israel can ask for land swaps but given Israel has illegally settled on Palestinian Land ,there is no legal requirement for Palestine to accept all or any land swaps. Until Israel presents a map of what it views as borders as Palestine has then the process will remain stalled.
