Maybe they can use salt water for it? If they have to desalianate it one would think that would be a dealbreaker. Tis a good question you ask. Why indeed. Just currying favor with the group that controls the superpower I suppose, what with the child fucking tapes Israel has on the president and a critical mass of politicians in the US and UK, and businessman and other swells. And whatever other blackmail. I can't think of any other reasons, other than currying favour with Israel.
