It is often stated that the vast Jewish "settlements" in the West Bank are an insuperable barrier to the two-state solution between Palestine and Israel. That is not the case.
Of course it is inconceivable that the settlers will ever leave or be evicted en masse in the way the Palestinians were.
However as the Israeli writer Amos Oz pointed out years ago they do not have to be.
Under a two-state solution they can stay where they are and carry on life basically as they have always done, except that they would be living under Palestinian sovereignty.
Of course they would need security guarantees. They could also be offered the option of moving to Israel, the US or perhaps other countries, and be given substantial financial and other assistance to do so. If the US were to invest in this way it would stand a far better chance of bringing security than the billions of dollars poured into waging war.
