US will not likely change its stance on Palestine, it might even harden.
A few days ago (ex) president Clinton Clinton remarked on the two state solution he had almost negotiated which gave palestinians almost all they wanted, but Arafat rejected it in the end.
He said both Israelies and himself acted in good faith, but there was one bad faith actor present, Arafat.
His conclusion ; we have to start all over.
My opinion is Palestinians under PA and Hamas cannot be trusted as it is. Maybe Egypt or Jordan should administer Gaza, West Bank, for at least one or two decades, supervise reconstruction, build sound civil structures. Prevent non state actors from emerging.
