Look at the difference in Defense and Commercial mix amongst Chinese and American primes.

Commercial market is brutal and hyper-competitive. It punches you in the face everyday. It makes you better, faster. Those gains compound.
Chrysler used to make missiles and General Mills, the cereal company, had a mechanical division selling weapons.
Commercial market pressure is required for compounding price performance improvements in design, manufacture, and operations.
Innovation is a consequence of productivity - and production and pressure for production improvements exist at scale in commercial markets.
At the dawn of WW2 we didn't have an Defense Industrial Base. We had an American Industrial Base.
That's what winning looks like.
