I was talking with a member of the Palestinian Observer mission to the UN the other day about a product I sell. I mentioned my discomfort about dealing with Hamas because I am Jewish. He pulled me up sharp [appropriately so] and said that the products will be used to benefit ALL of the Palestinian people, not just those on the West Bank.
The point is, if you treat a group as a unity, there is a chance they will all grow. If they become better educated and more generally prosperous, not just oil rich, there is a chance that all of the people in the region will get along.
