Two state solution is actually a three state solution as Israel, west bank and Gaza. West Bank and Gaza geographyically are seperated by Israel in between. So there cannot be two state solution , it would be 3 state solution. It would be much better if Palestinians put their efforts to be recognized as equal citizens of Israel and put pressure on the international community to allow the refugess back to Israel as citizens of Israel thereby creating one state for both the cousins of history to live together in peace and prosperity.
