It is not clear to me that the power here lies with the US Govt.

Imagine Anthropic is declared a "supply chain risk" thus cannot be used by all sorts of big industry players. How will the CEOs of those companies feel about the govnt telling them they cannot use what their engineers say is the best model? How many of those CEOs have a direct line to powermakers?

How many of those CEOs are already making the phone calls? The "supply chain" threat is a threat to every US company that currenly uses Anthropic.

Oh, and that includes Palentir, who is deeply embedding in the govt.

Side example: remember the 6 congresspeople who made the video about military orders? They won.
