If Israel gives up the land beyond the 1967 borders, which it continually asserts it does not want to annex, it will have a 10 year window to demonstrate to the Palestinian people that it can live peacefully with arab neighbors. I am willing to bet that the majority of Palestinians will come to accept it and lose the desire for violence. The alternative is to not agree and continue with the status quo for the next several hundred years or until the US wises up and stops funding this folly. Also it then puts the ball squarely back in the Hamas court where they have said they would agree if the people vote for it and after a 10 year truce the majority would vote for it.
