I have to agree with you ... I know Turkey has a pretty solid MIC but in aviation, it is still far behind that of France and the UK. The French and the UK have demonstrated their ability to procure top notch fighters for generations, with the most recent being the Rafael and Typhoon respectively. For Turkey just to entirely side step is going to be extremely difficult. For the TFX to succeed, it will undoubtedly have to use a lot of EU/American components, with the engine being just being the tip of the spear. Meanwhile, France and the UK have demonstrated the ability to build top notch gas turbines in the form of the M-88 and the EJ-200.
I highly doubt Turkey will have a domestic F-110-GE129 class engine by 2030. Just because it has access to the engine's technology does not mean it can build one from the ground up without licensing and TOT from GE.
