Nigger if all it costed was a few months of defense spending the US would have abandoned TSMC years ago.
As would have China and India.
You dumb fucks simply don't get that at that level of advanced fabs and incremental improvement it's not something you can buy off a shelf, because every country/region would have by now. It's a culture, one that for some reason the US, China and EU have been unable to replicate for decades now.
Building advanced chips is the most advanced manufacturing process on Earth by far, if someone can drop node size while you spend that much on now shitty wafers it's over.
No amount of government gibs or le orange man tarrifs will change that
