Well that is just ludicrous. In Gaza the Palestinian leadership is the one firing the rockets. Any "state building" is prevented by sanctions and Israel is also doing everything it can to PREVENT statehood. None of you Israel cheerleaders have addressed this yet. A one state solution would have to be a federation and would not allow free movement for quite a long time until equalization has been achieved. 20 to 50 years... probably.
Do you think that Palestinians and Israelis can live peacefully as part of one state or would it look a lot like the recent Balkans conflict or Rwanda or Iraq?
State building can occur under these circumstances. One can build hospitals, draft a legit constitution, put in an honest court system, fair law enforcement, good education under these conditions. It has been done by other countries at other times. The sanctions, currently, are quite tough, but have not been forever, nor will they be forever. Sanctions of various levels cannot be the excuse for every failure.
Sometimes it is the leadership firing the rockets from Gaza, sometimes not. But there is a need for Pali territory to be properly governed. One of the basic functions of a legitmate state is to make sure that the state controls the armed forces on their territory, so when they do fire rockets it is towards a rational political end. It needs to get done.
The problem with the one state solution is that the only people who like it are the radicals on each side. Radical jews want one state with no non-jews and radical palis want state with no jews in it. I am surprised someone who plays at being a moderate adopts it.
