From what I see from my perspective:
Last time it was on the table the deal was so good PLO realized it could be forced into a real two state solution with peace and permanent borders.
At that time the PLO, not Israel, left the negotiating table without even a counteroffer.
For me, from all I see from the rhetoric, Arab organizations want all:
- right of return for them
- no compensation or right of return for Jews forced into Israel from surrounding areas
- no permanent borders and peace, they see it only as a first step
> as that would require recognition of a Palestinian state as the PLO had wanted since the 70s
Let's also for completeness include that PLO want to eradicate Israel, and are brazen enough to have it in their official charter.
