They have, essentially, no economy. They have little arable land, and their water supplies are almost all (except for that which is supplied by Israel) contaminated with salt and (mostly) sewage….They can barely (OR NOT) grow enough food to feed their people….
So who pays the bills? Water, energy, food, etc? Where does the money for this come from? Who pays for the people, the infrastructure (what is left)? It certainly isn’t from exports or industry….Someone is paying….It isn’t Israel, it isn’t Jordan, It isn’t Syria and it isn’t Egypt. None of those countries, not even the majority Muslim ones, wants the “Palestinians” as refugees, and they aren’t giving money to feed, or house the folks in Gaza..
So who is?
