> about security and economic on-shoring > increases the likelihood smaller states can build locally and solves for most chip needs I'm not sure what does that mean? What specific chip needs that would that solve and what benefits would this provide? If those chips are not competitive nobody would buy them? So what would governments do with them? Stockpile them for the future just 'in case'? The problem is that unlike grain or oil chips are not exactly fungible if your military production or other vital industries lose access to their current suppliers they wouldn't be able to use your slow, outdated and overpriced chips anyway (and forcing them to do that under normal circumstances would make your products less competitive). > BOM for the challenger tank How many other components does the Challenger tank contain (IIRC it's not really produced anymore anyway) which are not manufactured in the UK? In any case stockpiling necessary chips etc. just in case the UK won't able be able to acquire anything from the US/Germany/etc. seems like a practical approach than trying to develop everything inside the country.
