President Obama understands what I wrote three and a half years ago, that ending the Israeli Palestinian conflict depends on recognizing that "the solution essentially comes down to understanding the most and least that each side can accept".
We could argue forever whether the State of Israel should have been created the way it was but, as most Palestinians have come to accept, that is a historical fact that is simply not going to change. It has been a huge and difficult step for the Palestinians to accept that, after all it was their land that was stolen from them. But come to accept it they have. That is the most they can be expected to accept. The least they can be expected to accept is to have their own Palestinian State and have Israel give back the land they stole since the creation of the State of Israel with no exceptions. The original boundaries must be restored, including the status of Jerusalem at the time Israel was created.Hard line Israelis, and their even harder line supporters in the United States, may not want to accept anything other than a solution dictated by Israel but the rest of the world knows, and President Obama understands, that Middle East Peace will require compromise, and while the hard liners may not want peace the rest of the world does.
The least that Israel can be expected to accept is to have their right to exist accepted by the international community, including Palestinians and Arab states. The most they can be expected to give up is all the land they stole after the creation of the state of Israel, a not unreasonable expectation.
