>In that case, give it 6 months or less for US TSMC foundries to produce the finest.

It's really a blind belief in american exceptionalism that makes you think this is even possible.

No, the chip factory that has had dozens of years of experience and local talent scaling up to make the most complicated products in human existence doesn't magically get up to par in 6 months. At best in 6 months they've figured out how to be less sensitive to vibrations and reach a low yield. The US doesn't have the trained workforce for this job, nor the infrastructures _around_ the fab (specialized hardware, electronics and engineering schools, various bits and bobs).

US TSMC doesn't get properly running in less than 5 years, and even that would be a miracle. You're also assuming that US TSMC has the current N2P or even N3E processes, and that agent orange doesn't burn bridges with europe hard enough that ASML stops selling to anyone related to the US.
