You are absolutely right – but Turkey urgently needs access to American/European high-end platforms.
The best example of this is the TAI KAAN: without participation in the F-16 and F-35 programs, this project would have been virtually impossible in its current form.
This is not about imposing new dependencies on ourselves with an aircraft overburdened with ITAR restrictions, but rather about diversifying our own fleet. To do this, it is entirely sufficient to procure 60–70 aircraft in order to participate credibly and effectively in NATO operations – purchasing over 100+ aircraft is therefore not necessary.
Another aspect is the nuclear dimension: Currently, the F-16 is Turkey's only platform capable of carrying US nuclear warheads in Incirlik.
Even if their use would only be possible with Washington's approval, this factor remains a strategic element that should not be underestimated in view of the future security situation with Russia and China – no one knows what will happen in 10–15 years.
It is unlikely that we will ever use it, but having access to it is deterrent enough.
Neither the US/EU nor Russia/China are friends or true partners, but access to it is key to showing Russia and China that we can become pro-NATO again if necessary and if you exert pressure.
Furthermore – and I'm sure you'll agree with me here – Turkey needs comparable high-end systems.
Only through detailed analysis, cooperation, and direct comparison can the KAAN and its successors be consistently developed and improved technologically.
A role as co-developer or OEM partner in the GCAP program would be a valuable step in this context.
The passive transfer of technology alone would be enormously valuable.
