Well, most of the companies that tried and failed can be faulted for two things. First, they were criminally stupid! They all hired lazy arrogant managers, and allowed same to lead them to ruination. Second, kickbacks and other "cash drains" on revenue took their life blood. Finally, pilots were treated quite poorly, so it quickly becomes a "us vs them" downward spiral.
The Middle East is a gold mine, they just need a few operators with local knowledge, business savvy, and good management. Surprisingly, this has been hard to find, like water in the ---.
