Finally, a very valid question!
A 5 to 10 bln € participation (in TFX) from Qatar is even less than peanuts...considering how much they have committed to spend on a few French and US fighters...with zero leverage in return.
Turkey stuck her neck out for Qatar in the present GCC crisis...with some considerable cost in diplomatic relations with other GCC countries... so if Qatar has any sense of gratitude or self respect then it should demonstrate by investing in TFX and other shipping and aerial programs that TAI and other Turkish firms are pursuing...
Otherwise, I would say Turkey's goodwill and support is taken forgranted.
It is upto Turkish Gov to 'persuade' Qatar to see the light.
But let us see what happens!!!
