Uncle Sam wouldn't allow that. Why not just sell them to Egypt, Indonesia, or some country like that?
Uncle Sam is butt hurt over Venezuela and would not let them sell them to the USAF even if the USAF needed them badly.
They won't be able to openly sell them to anyone because that would mean Venezuela getting money and they don't want Russia to sell gas to Europe because Russia gets money... why would they let Venezuela get money from selling their planes?
New Zealand is supposed to be a US ally but they stopped us from selling our Skyhawks because they had upgrades in them that were also used on F-16s.
It was nothing to do with keeping anything secret... they were just butt hurt because they expected us to return the Skyhawks and buy F-16s instead...
