Geographically the west Bank and Gaza are miles apart like Pakistan and Bangladesh were before separation. The ideal solution at present would be a three state solution. This would be easier to achieve as it puts away with the Palestinians infighting. If in future the governments of the West Bank and Gaza would like to integrate into one state let it be so. Gaza as such, does not have border problems with Israel. What is needed between Gaza and Israel is a policy of live and let live which is achievable as both sides will gain a lot from this new situation. Once the Gazans are happily employed and earning a good living thy will think twice to go back to the present times. On their part the Israelis may also live in peace. May your god help you to a better life.
