In the funniest timeline, the US nationalizes Nvidia to delay China from making chips that work well with LLM's... by a year tops.

To do that, Raimondo said the Commerce Department’s Bureau of Industry and Security, which manages export controls for the US, needs more funding from Congress.

TSMC doesn't make their manufacturing tools. They buy all of their production tools from other companies (ASM, KLA, Hitachi, Applied Materials, Tokyo Electron, etc), they only create the facilities and chip designs. It's the same structure throughout the whole semiconductor industry.
They don't create the chip designs, they create the manufacturing processes, which aren't as difficult to catch up to as people think.
I work in manufacturing. If there's is a will, there's a way.
