I think it's not too late. We have lots of time before the election. I think anyone who can make peace in the Middle East, even if it's just walking things back to a previous stalemate, has a hell of a foreign policy win.
That being said, a reset to where things were before does little for the Palestinian people as regards the original cause of this violence, and I wonder whether they will be largely forgotten or if they will continue to be important to American politics the way Ukraine has.
