What more can the Palestinians give?
Right of return.
No chance of that as they have already said that they will not allow any Jew to exist in Palestine that was born after the invention of Zionism.
That isn't actually what they said.
Yes it is and they wrote it down in their charter for the world to see.
Which "they" are you talking about?
The Palestinians who have ruled Palestine since 1988 of course. They have the same meanings in both of their charters if you look
