Of course this would not make it possible for the Palestinians to have the contiguous state they claim to desire. Which brings us to the next topic:
Why should a ‘Palestinian’ state be created on the backs of the Jewish People?
Israel does not owe the Palestinian Arabs a state, in part because the Palestinian narrative in which ‘their land’ was ‘stolen’ is false, and in part because a ‘people’ whose culture is based on hatred and whosehighest honors are given to the most vicious murderers are not owed anything by a civilized world.
Keep in mind that when offers of a contiguous sovereign state were made, including evacuation of many Jewish communities (2000 and 2008), they were not accepted because they did not include right of return or other conditions that were incompatible with the continued existence of a Jewish state next door.
The political organization appropriate for the Palestinian Arabs in Judea and Samaria is probably not that of a sovereign state. I believe that the best that can be offered today is some kind of autonomy, in a framework of Israeli security control.
There are other ‘peoples’ that don’t have their own state, for various reasons. There are 22 Arab states in the Middle East — all of which define themselves in ethnic or religious terms (or both), by the way. Why create yet another, at the expense of the one tiny state of the Jewish people?
