You have to allow fo cultural differences here. English people think about as far back as the days of Empire, if they can be bothered - but Middle Eastern people believe that land is theirs by right and has belonged to their people since biblical times, and they can, and will fight to the death to defend it. It's a tradditional approach to their own land, and that of their neighbours, and it is indemic, in a way that is very hard to us Brits to understand. The nearest we get is the Gaelic peoples who have more of a sense of history, but to the English, their fervour and commitment and absorption of their history is difficult for us to grasp. There may be a solution, but the protagonists will fight every inch of the way to protect what they believe to be theirs, and the solution will be slow and painful in coming.
