Those plants are national assets from a defense standpoint. We would need them i.e. like we did in WWII this is foolish.
Spoke with a friend about the Santelli oil spike prediction. His synopsis (he is in the raw matls/chem arena)? It is China based demand. Steel is in demand here, but we have only one iron pellet US source. That to me that is scary.
Do we have the ability to build complete airplanes still?
Yes, I know we can assemble the airframe, but can we even come close to providing the avionics package?
It is a China based demand, coupled with increased usage of oil products in Russia and other oil producing nations (leaving less for them to export).
