But surely that should be ASML's choice?

[someperson]

ASML machines include a large amount of technology from the US, and so can be controlled under US export control laws.

A country is free to develop all those technologies locally and not face US export control, but that's such a difficult task that nobody has achieved it.

_Every_ country is subject to US technology transfer laws if they want to retain access to the global banking system.

The US can simply put an offending company on a black list and every financial institution will drop them.

ASML is a Dutch company that doesn't export from the US

[Slikey]

That doesn't matter. If they want to export TO the US they are subject to US export laws. The US has a history of their economical and political power forcing companies that have no business with the US to do their bidding to stay in business. Just look at the Iran sanctions.

History has demonstrated that public companies aren’t going to make the right choice from a Western POV.

Short term gain always beats strategic defeat.
