Definitely defense, if you study history - how bacon grease was collected from homes to make lubricant for cartridges during WWII; making pins and buttons for clothes was turned into component manufacturing for airplanes almost overnight. Within a few days, people worked to convert equipment, draft new mechanisms, turn them at the machine shop, fixer-upper some machines - converted the entire enterprise into making shaft pins and washers. There were countless examples of how quickly manufacturing of A was converted to manufacturing of B. Ken Burns documentary goes much deeper into this and I find it totally fascinating. Chinese populace has an insane level of "jerry-rigging" capability because of how they bring costs down. This is a huge advantage in war manufacturing theater. This is now questionable as Americans (and Europeans alike) are constantly in consumption mode.
