ITAR blocks export, not import. It has nothing to do with TSMC building fabs here. $50B in incentives might have something to do with that.
And like sister comment says, ITAR is not about industrial or economic policy. It’s about maintaining a qualitative edge in weaponry. How is there a qualitative edge when you can buy the restricted components freely from China?
Just noticed the other comment on GP saying they’re restricted through a different list (EAR). It serves the same purpose so I’m leaving my response as is.
A benefit of those same restrictions means TSMC is building foundries in the US for a change.
GaAs sensors are awesome. Combine those chips with ML optimized compute on a silicon interposer and drone warfare gets a hockey stick in adoption.
As civilians we get functional self driving cars via trickle down.
