Finland and Sweden have done what the three countries agreed on in Madrid. Turkiye has added more conditions for approval of Finland and Sweden. The Turkish economy is in the drain, Erdogan wants to be reelected and what is better than portraying himself as a strong leader. His objections have been directed to the US and I bet he will say yes if he gets the F-16 upgrades and the new F-16. The US has another possibility to pressure Erdogan and that is to sell more advanced weapons to Greece.
The Greeks are already part of the F-35 program, I think they purchased 20-25 of them about 6 months ago.
I think the significant part of this though is the comment that "Once the NATO accession protocols are ratified by Türkiye, Congress can consider the sale of F-16 fighter jets. A failure to do so, however, would call into question this pending sale,"
This is not a "give it some thought" comment, it is a "sign it or else" comment, Erdogan has no wiggle room left.
