A huge percentage of the nation's R&D efforts (for DOMESTIC MANUFACTURING) is going to be completely and utterly fucked if they can't rush-deliver niche items from China. This is a disaster.
And it's not just R&D! If you have a big factory here in the USA but you need a rare part/tool/electrical component to fix the factory - often the OEM you buy it from will ship it from their China warehouse and it'll arrive in 1-4 days.
As a person who works in domestic manufacturing, this seems really, really bad for domestic manufacturing.
