What I don't get is Turkey advertising it's so-called 5th-Generation fighter, after having been kicked out of the Joint-Strike Fighter program and cancelled deliveries of the F-35s. Turkey is buying up spare parts for its huge F-16 fleet, in anticipation of America expanding it's punishment on Turkey for being adamant about buying S-400s. Then how in the world does Turkey think it would be able to develop their 5th-Generation fighter without any engines? I mean if they're thinking that European Union would be able to collaborate with them, then they're more naive than I thought previously. The E.U has shown clear evidence that it cannot exercize independent foreign policy, as it gets stamped down by U.S under the "NATO" treaty. So what is Turkey hoping to accomplish here? It is in way too deep with U.S arms to ever hope to get out of any U.S sanctions or exercize it's own foreign policy. As far as I am concerned, if Turkey follows through on it's S-400 procurement. Then it will face further repercussions, severe ones, from the U.S, without a doubt.
