The reality is that F18'es are a complete waste of money as they're simply targets for most of the newer Russian kit. The testing they did wrt the teen series in general (15,16,18) vs late model Flankers & triple digit sams was not pretty.
In fact (in keeping with the IT bent of this place) the really nasty threats are that dear old linux etc is giving the really old SAM's a whole new lease of life. Pop out the old controller, pop in a new one built from a smartphone et voila bit's of fighter come down like leaves in Autumn.
& that's before the fact that passive radar works now that processors are cheap & powerful & we're all bathed in radiation from phone masts, FM transmitters, satellite TV etc.etc. Heck flying over a populated area with widespread wifi routers is a a stealth nightmare
Basically it's down to drones and airliners. Pilots don't like it because the airliners simply do racetracks a nice safe way back & provide refuelling for the drones, a nice comfy room with a view, and a signal repeating function for the drones.
The same is happening on the ground with the whole MLI (Modern Light Infantry) process i.e. man portable weaponry + a laptop & if you need transport use a 4x4 truck which can be cheaply sourced locally and is expendable vs damn great tanks & heavy kit in general. Even artillery can be sourced by rockets (including vertical launch containerized pods) or via drones.
At least the Taliban, Hezbollah et al have woken to this but then they have less budget for toys.
The F35 is the last hurrah of the fighter jock but at least the flat tops are by their nature....flat tops so will still find a use as an airbase.
