What a childish statement to say "they can take their airplanes back if they don't let us in."
That goes beyond childish. What does buying Boeings have to do with the State Department and the FAA letting in a foreign carrier?
Just goes to show you how the middle east operates. In the sand with the Command Economy one man or one department decides everything. In the Western world you have checks and balances and many different facets of the economy. One man doesn't decide everything and can not interfere in an area that does'n't belong to him.
The Arab world will never learn.
