Not sure why any of that matters.. its their land, they did nothing to deserve loosing it and were simply invaded. So until the occupying force leaves and especially when they are the ones overpowered and forced into ghettos,then there is absolutely no chance for the Israelis to be the good guys.
The whole "but we built up the area after we stole it and killed everyone" is a pretty damn poor excuse for why they should keep it.
