I think it was Alvin Toffler who predicted last century that the 21t century would feature Islamic Jihads and wars fought over water. The Nile, the Tigress and the Jordan were all candidates. Before anyone gets on their high horse, look at the water problems in our own West. California regularly takes water from others and the Rio Grande is nothing but a few muddy puddles when it reaches the Mexican border.
With the water from the Nile the rest of its tributary countries have an opportunity to develop. But Egypt will suffer in equal measure to their development. The Turks said they would never use water as a weapon...yeah, sure.
One bright spot in this is Israeli technology for desalinating sea water. That and the advent of cheap modular reactors might prevent a few wars, but that is a long, long way off. A lot of people will die before they either accept Israeli help or the world allows more reactors, regardless of how safe they can be made.
We have our mighty rivers, including the mighty Mississippi River. I am from a state that has its own mighty river, called the Connecticut.
All good points. Excellent read.
