Useless AF’s
Anyone of these AF’s that maintain a symbolic “air-defense” capability with 12 or so jets. That means the likes of Croatia, Qatar, Hungary (how many of those MiG-29’s are actually operational?), Czech Republic (L-159 is a glorified trainer), Moldova etc.
12 – 20 jets are not going to last at all in major combat operations so maintaining such an AF is a waste of taxpayers’ money.
