Yeah, having fabs in the US as well as other countries could pay off yuuugely. If potential fab customers are truly afraid of Intel copying their designs - Intel could enter an agreement with say Qualcomm that it won’t design any ARM CPUs for X years. Surely there’s a market for US made SoCs once you can assemble the logic board of a smartphone in the US, and a smartphone from parts. You’d still import some parts but shift production to the US for what’s possible - but you need to start with the end product and work your way down because otherwise you’re shipping components back to China for final assembly. And the more expensive the components you can produce in the US, the less you’re affected by tariffs.
