Without a two-state solution, what is there?
Either a three state solution, which would be more sensible, or have Gaza incorporated into Egypt and the West Bank into Jordan which would make the most sense of all. .
Three states being Gaza, West Bank and Israel? I could see either of those as possible but not probable because neither Egypt nor Jordan want to take the Palestinian issue on.
But they will have to sooner or later, so why not get it over with now. Make them an offer they cant refuse and implement it, say annexation of gaza by Egypt and the west bank by Jordan and then to hand the land to Israel as a gift.
