I do think there is some merit on too much focus on a peer conflict in the future. While I do agree you need to look to the future, and develop the best for the future, perhpas there could be more focus on "good enough" programs and keeping existing fleets in top condition. A "high/low" mix is preferred to ensure you have a good mix of world beating and good enough platforms, and pehaps there has been too much focus on the "high" end. Insisting on the gold plated F-22 and F-35 and the next generation bomber seem to support to much emphasis on world beating technology.
The apparant abandonment of the A-10 and the lack of a "low" COIN aircraft indicate too little emphasis on low. The recent COIN programs for partner use came up with warmed over Tucanos and Texan II's- is that really the best that US aeropsace can come up with?
A new build F-15 is another example. With improved avionics (yes expensive) and a zero timed airframe you would have a fighter that would likely be "good enough" for most conflicts.
The USAF insistance on fully qualified pilots as drone operators is indicative of a pilot run organization, and perhaps slow to change. The power of the flight suit is strong.
