A friend of mine, a professional negotiator, suggested this approach for a Netanyahu "miracle" speech in Washington:
The Israeli Prime Minister should announce the he is willing to negotiate with the Palestinian Prime Minister for an independent Palestinian state, at once, without any preconditions for either side. Everything would be on the table--for the Israelis as well as the Palestinians. He would be willing to stay on in Washington, to go to Camp David, to move talks to Jerusalem, wherever Abbas wants. He would stay as long as it took to reach an agreement--just as at Camp David. President Obama could mediate, or not, as he saw fit.
Can we make peace? "Yes, we can!"
If the Palestinians responded to the offer with intransigence, that would be their decision, not Israel's.
In my opinion, Israel could then unilaterally declare borders prior to the September 1st recognition of the state of Palestine by the UN.
If there were to be a border war after that--well, even the US fought a border clash with Britain in 1812...it would not pose an existential struggle for either side.
