The palestinians have accepted all UN resolutions and the State of Israel meaning 78% of the territories they used to live in are now Israel. One should not forget that a very large majority of palestinians was living in Jerusalem, Haifa etc and they have been kicked out. This is by far the biggest "concession" as opposed to those israeli "genereous offers" made by Barak or Olmert regarding some territories on the WB. Palestinians are here to stay. They will never ever be kicked out again.
