The Middle East of today is not the middle east it was yesterday and neither is it what it will be tomorrow.
In my lifetime I have seen country and city names change. Boundries change, alliances with nations change.
I seen Persia become Iran. Constanople became Istanbul, French Morocco and Spanish Morocco became Morocco. I watched much of North Africa switch alliances from Spain, to France, to Usa, to Germany and Italy, Back to USA, to Saudi Arabia. Etc. I seen prdominetly nomadic people settle down and become city dwellers after thousands of years wandering the Sahara and then Settling in Sudan, Eritrea, and Ethiopia. I seen Saudi Arabia go from isolation from the world to the modern technology of the 20th century.
Yes, there will be a new Mid-East, The only questions are what countries will be welcome into it.
