There are really only two alternatives:
1) A Palestinian State alongside a Jewish State.
2) One state covering the entire former Palestine Mandate, with all Jews and Arabs getting voting rights. The way the numbers work now, about 1/3 of the Knesset would be Arab is Israel were to properly annex all the territories (annexation requires giving citizenship and voting rights to all persons living in the annexed areas).
I will support whichever of these alternatives Israel want.
