>Yes, you can probably build a cheaper Tomahawk missile today. However, can someone else build a cheaper drone that is even better for the battlefield theaters of the next several decades?
I heard the US produced knockoffs of the Iranian ~$10-50k drone and produces it for ~$35K and its a modular and an upgradable platform (ie. not just a dumb copy). If you ask me, that ability to not only produce castles but also 'cheap cannons' as per your analogy when needed for cheaper and then improve on top of it is a pretty darn good skill.
Much of WWII was based on overwhelming cheap (and field reparable) machinery backed by industrial capacity while the Germans had the finely crafted equipment.
Somewhere in the next decades, the US has switched to being the finely crafted military equipment.
The point I was trying to make that seemed to go completely over OP's head is that the US appears to be nimble and pivots fast enough to be able to do both when needed.
