You have a point... right up until the next major war and we’re entering that period right now. 100 years between major wars seems to be the established pattern. The British Army and French Armies prior to WW1 were very professional and very experienced at small colonial wars. The Kaiser’s Army dealt a near death blow to both in 1914. Point is: you don’t necessarily get to chose the fight if your enemy brings it to you.

You want to place your entire national defense in a few airplanes that can easily be shot down or fail to fly due to ridiculous maintenance schedules??
You talk about 100 year wars, yet you fail to recognize the Germans were defeated in part in WWII because quantity is a quality all it sown and they spent time, money, and resources on bleeding edge weapons that allowed them only to buy a few.
