Turkey needed an Air Defence system urgently, it was basically an emergency because there was no high altitude ad system. The only defence we had was our own fighter jets.
A stealth fighter jet is less important and not an emergency because non of our neighbours have it.
The West did not sell air defence systems. And Russia was willing to. The Singaporean military estimated the F-35 would run for only 4 months after a US supply embargo.
Ukrainian S300 have done an amazing job denying Russia air superiority. I also think drone strikes are assisted by EW.
i think Turkish High Command knows more than the F35 fanboys here. Let's develop indigenous systems so we don't have to suck up to them.
