Stop assuming things.
I didn't think there were any homes to go back to. But anyway, up to them. I don't think Israel should pay for rebuilding since hamas terrorist attack started this particular conflict off. Many hamas funds sat in Qarat bank accounts could be utilised first, then Israel contribute.
The world's billions in aid should be distributed to people and not stolen by hamas for selling for their gain (sneaky bastards, doing their own people out of freely provided food etc).
Hamas gone (will they go, or hang on though) and if any exist moderate Palestinian leaders or if they cannot find any a coalition from other countries.
In the end the one thing many hopefully agree on is no hamas, but have to get rid of the nasty shits is going to be difficult. They won't go voluntarily, do the people want them gone, by the cheering and clapping when they strut their stuff who knows.
