Do you think US had a vast supply chain network and skilled manufacturing workforce in 40s? When most men were gone fighting and women replaced them in factories?
US prodution of airplanes for instances exploded during this period. And yeah, they are very much capable of doing it.
All this supply chain bullshit you believe will go out of window the moment they decide to invoke Defense Production Act. That removes profit motive and lets US to produce things at a warfooting.
Remember, US was able to mass produce mRNA vaccines during 2020 pandemic? There was NO supply chain for mRNA vaccines anywhere because it was never mass produced before.
That vaccine was used to vaccinate entire western europe and americas.
How do you think that happened? DPA.
