The only things that matters for this consideration are: A. How bad is the consequence of not having them? B. How long does it take to tool up domestic production if there's a supply disruption? C. How long can you tolerate the shortage of them? D. How easy is it for a disruption or disaster to disrupt international supply? The answers to A and D are fairly different, but both are "bad enough" to trigger this kind of thinking. The ratio of B to C are probably similar between food and critical integrated circuits.
