All the Western countries upgrading to 5th gen / F-35 / etc will free up countless F-16's and other similar aircraft. Used should be fairly cheap. And there are thousands of F-16's alone operating globally outside the US. Ex: Norway sold it's F-16s to Romania, in 2022; and just a few days ago, Argentina decided to abandon the JF-17 and opted for used Danish F-16's.The aerospace industry is in a peculiar place right now as there are no cheap "proper multirole" aircraft already in production or entering production apart from:
Western aircraft are too expensive. T-7 won't make it to the market. Turkey plans to replace F-16s with 5gen. Lack of outsourced F-16 production will maintain cost barrier.
The US controls the Iraqi budget. Iraqi government funds are stored in US bank accounts. And the US has a say in how they spend their own budget. It's a US colony.
