Abbas can't do a thing about a peace overture because he will be assassinated.  He knows that.  There are no heroes for peace in the region because the politicians, the mullahs, and the ayatollahs have had the pulpit since 1947's partition of the British Mandate.  Trump will soon learn that he has no one to "deal" with in the Palestinian upper ranks.  There are no more Arab generals who understand the situation and will deal.  Even they are assassinated. Israel will have to declare a one nation with two separate voting states under Israel's border controls.
