Gripen is more difficult option to be bought than f16. Gripen is actually the embodiment of European and US components so handling the permission of one component will not guarantee the other. The best option is still the EF If UK is still in same position about EF's source codes.
The second issue is the sale of the F16. As can be seen, a senator who speaks with bribes every day comes out and comments on the sale of the F16 and proposes new conditions. The guys we are talking about are part of a deep state structure that has changed the name of the PKK which they actually consider a terrorist organisation and introduced it to the world as angels of freedom and now tries to demonize Turkiye over it and issue embargoes based on operations Turkiye carry out against PKK and issue conditions not to use their weapons against PKK. For such structures, every sale is actually a political move.
Therefore, No matter who rules the country, the only way to buy F16s or sonething serious from USA under these conditions will be possible if we take the position of surrender they want. For example, the guarantee of not being a threat to the lands US is trying to divide with PKK in Syria, the approval of Finland and Sweden's membership, act like a docile cat against Greece which they use as a pawn and that we do not defend our legal sea rights against all kinds of unlawfulness and Greek claims. Otherwise, every new day a hired congressman will set new terms and continue to use the F16 as a tool to belittle us.
What we have to do is prove that we don't need them anymore. In the upcoming dates, it must be organize a very spectacular introductory ceremony for Hürjet and TfX in a way that will include all segments of the public and participate in the flight of the KizilElma and/or introduce new twin engine variant prototype with participation of all levels of the public representatives and to put our surprise missile systems on them. In this way, it will be to remind how the pawns they are encouraging against us will remain in a cloud of dust and fire when the time come and to show that F16 can no longer be used as a political trump card against Turkiye. I have no doubt that they would start begging to sell the F16s if one of those programs was in advanced stage in flight trials.
