The middle east is growing economically as the Untied States and Russia pump money and weapons into the area. These war ridden nations are still deciding on which side they want to join, so everyone is trying to "help". Most of us know that war increases economic opportunities and countries like Israel and Saudi Arabia are great examples. The economy of most middle east countries have always been on the rise since the popularity of oil, but now they are the main attraction of the world.
I hope this helps! :)
