The more they sell, the less likely China & others are going to make a real alternative.

They will still make a real alternative, it's in their own national security interests to do so.

If national security interests drove development, the US would have local manufacturing of current-process-node chips instead of being dependent on TSMC.

If 5nm semiconductors were essential for some military core capabilities, they'd start building the whole production chain domestically in a hurry at eyewatering cost and probably finish it over budget and 15 years late.

There is also a massive difference between making them uneconomically and making them economically at scale.

This is not my impression of how things generally go with China.

These could be used for military purposes, wouldn't the best use case be let them try to make a real alternative instead of providing them the tools?
