I think that the Zionist cause is well past its sell by date...they are still there in the Middle East purely because of brute military strength and through the massive economic muscle and aid provided by the USA and other western governments.
There will be no 2 state solution because Israel will accept nothing but a series of bantustan type strips of land for the indiginous Palestinian people to live on with no power ,no freedom of movement and at the mercy of the Israeli state itself and any crazed armed Zionist settler who wants to shoot at or beat up a Palestinian.
There can only be a one state solution some time in the future and any Zionist who cannot accept that should return to New York or some other place but there will be no room in the new state for their thuggery and armed swaggering!
