Gaza and the West Bank are not, nor have ever been, part of a contiguous legal and geographic entity. If you want a Palestinian state where both Gaza and the West Bank form a united state, you would have to request that Israel grant right of passage through her sovereign territory for people wanting to go from one part to the other. Such right of passage is quite unprecedented. Therefore the Arab states should lower their expectations and demands with regard to other issues.
