Syria and Egypt are dying. They were dying before the Syrian civil war broke out and before the Muslim Brotherhood took power in Cairo. Syria has an insoluble civil war and Egypt has an insoluble crisis because they are dying. They are dying because they chose not to do what China did: move the better part of a billion people from rural backwardness to a modern urban economy within a generation. Mexico would have died as well, without the option to send its rural poor - fully one-fifth of its population - to the United States.
