I think your analysis is sophomoric. You need both antibiotics and microchips in a large scale war. We (the US) don't make a high volume of weapons ammunition such as artillery shells because we have a huge stockpile that is carefully managed and rotated. We make new shells, they go into storage, and the older shells come out and are used for training. Production went from about 14k shells per month a few months ago to over 30k per month today, and will flex up production to over 100k shells per month in the next year. That is just a relatively mundane engagement of our production capacity, if military planners believed they needed 2 million shells per month we would be able to reach that level of production do that in less than a year.
