This basic belief allowed us to write trade deals that reduced manufacturing capacity relative to non-manufacturing.
Totally agree with you the Ukraine war has been incredibly important in previewing what would have been much worse in a Taiwan war.
I think supply chain risk through peak COVID is also a huge factor giving this shift momentum. Supply chain shocks were comprehensible and visible to most Americans and impacted practically every business owner. It kickstarted renewed calls for localism and reassessments of worst-case scenarios for business continuity. Bringing up the home industrial base is a necessity for shortening those supply chains and bringing that risk under control.
Reducing risk from suppliers based in countries where government policy is less predictable or west-aligned was also highlighted by the pandemic. Shanghai locked down in May 2022, for example, and I am sure many Americans were surprised and annoyed at the time.
The one-two of COVID then the Russia-Ukraine war seems to have knocked us into a new alignment. Remains to be seen how it plays out against our current, difficult social backdrop.
Industrial base takes time to spin up, but if you have solid economy (as the US currently does) then using monetary policy and other incentives to push capital toward industrial base development is good for the country. It also plays well on TV since these factories are revitalizing towns and cities that previously were suffering from a lack of industry.
As a result, I don't see these shifts so much as a "reversal of Reganomics" so much as a realization from the Russian-Ukraine war that "globalism" isn't something authoritarians really like. And if you're primary trading partner is run by an authoritarian regime, that is bad.
