Ken, I think that I was trying to say that if it is taken as read that 5th generation planes are so much better than 4th or 4.5 generation aircraft, with an 8:1 kill ratio over non 5th generation, then you are as I read it suggesting that any country not training pilots for 5th generation is wasting time, as they will be pure cannon fodder, albeit expensive cannon fodder?
"Any country"? Absolutely not. For many nations a 4th gen fighter would be ideal. It is unlikely that nations like Brazil, Indonesia, Pakistan, and many others will have a need for a stealthy tactical aircraft designed to defeat integrated air defenses or engage in combat with 5th gen opponents. In similar fashion, back in the day a simple day fighter like an F-5 or F-16A was "good enough" for many air arms while the top tier air arms were acquiring sophisticated F-4s, F-14s, F-111s, F-15s, F-18s, Tornados, MiG-31s, Su-24s, etc, etc.
