I think GlobalFoundries pretty much abandoned the idea of actually improving their tech (https://www.anandtech.com/show/13277/globalfoundries-stops-all-7nm-development https://www.anandtech.com/show/13277/globalfoundries-stops-a...). I'm not sure what's changed since then. It may work for GF, but it's not enough for national security interests - critical parts of the supply chain depend on a potentially hostile foreign power (and it's not just silicon). I'd say the US should invest in TSMC, and push to expand manufacturing capabilities to domesticate some production - but good luck convincing taxpayer's that that's a good idea.
