IMO, Qatar's EFs are hardly second-hand. They received their first jet in 2022 and as far as I know, full operational capability has not yet been declared. Deliveries have not been completed anyway. In fact, the Qatari Air Force has purchased more aircraft than its capacity, almost like filling its plate from a buffet, due to the comfort provided by vast financial resources, political support recruitment-lobbying and planning mistakes. Qatar's special position is its network of diplomatic relations, not hardpower. Apart from the EF, Qatar also continues to order F-15s and has 36 Rafale aircraft, some of which are in Konya. Very probably, they will also want to buy KAAN in the first available schedule.
The Kuwaiti air force is a bit more reliant on the EF. So even if we take this speculation as true, I don't see Kuwait and KSA as likely, the country he is referring to is probably Qatar.
On the other hand, I think that there is a negotiation package that aims for concrete significant progress in defense cooperation with the EU region, including not only the purchase of 20+20 EFs, but also additional A400Ms, MRTT kits and its domestic retrofit activities. Even though no longer a must for us, we can expect an acceleration in the joint air defense project, taking into account the needs for EU. From unmanned aviation to air defense, we are no longer just buyers; there is significant mutual potential here. Joking but true, if they give the Eurodrone project to Baykar or TAI, they will have a ready-to-go platform within 2 year.
