I do not think US will allow Nato members to enter into an actual air war against each other but lets say such an event does happen and Turkey goes against Greece-France-Egypt alliance and US has to take side..
USA even deployed 15 F-15 Fighter Jets in Greece
everything for tiny İsrael .....
smart İsrael-USA uses proxies FETO, PKK/YPG ,Greece , Egypt against Turkey
France has its own interests in Syria,Libya and in the Eastern Mediterranean against Turkey
USA will not sell even F-16V to Turkey ...... no need to lose more time
Turkey needs new Fighter Jets and Russian SU-35 , SU-57 can protect balance of power in the region
otherwise Turkey with only F-16s can not match with F-16V , F-15 , Rafale , SU-35 ( USA-France-Greece-Egypt alliance )
also S400 will add deterrence to the Turkish Armed Forces
for Naval Power , Turkey has tons of weapons to turn all enemy Warships into crap of metal , if they enter Turkish EEZ in the Eastern Mediterranean
