While your facts are correct, I don't agree with your conclusion.
1) Offensive capability is MUCH more costly than defensive capability. Example; Stealth technology vs. electronic attack.
2) Sensor fusion is a great concept but still think it's nice to keep a man in the loop. Example; I don't want my jet to have a check engine light - I want to analyze what's going on by looking at the instruments.
3) If long range missiles were so reliable all our fighters would be designed with the same g capabilities as a C-17 and much cheaper, lighter, faster, and have much better range.
4) On tech / tactics - I would say flight that like almost any other technology has a curve of diminishing returns. The Wright Brothers flew in the early 1900's. Less than 70 years later we* put a man on the moon. The F-22 or F-35 doesn't fly 10x as fast as the F-4 or 10x as high - the progression is not linear.
I HATE the F-35. Our senior acquisitions folks are in bed with congress who are in bed with LM and the end result is an overpriced, under-performing aircraft that no real fighter pilot wants.
Read Boyd - the gold plated fighter returns. We need a Boyd right now to kill this cancer in the DOD.
If I were to design a fighter it would have:
10-11g capable airframe
Very low wing loading
Specialized for the mission (I.e. A-10 vs. F-22)
Excellent cockpit visibility
LOTS of internal fuel
Two motors to provide for a high thrust to weight ratio and thrust vectoring
Stealthish design but not at the expense of maintainability
Internal gun with lots of bullets
Internal reprogrammable EA capability
Sensors commensurate with the latest F-35 stuff
* real men with slide rules and mustaches.
