Perhaps. Who cares? It is a publicly traded company with widely disperse ownership.
I don't know about stock ownership,but for sure the IPs ASML uses for the cooler machines are all licensed from the US government.
The technology was developed in national labs in 1980s and 1990s and licensed to Silicon Valley Group, which was bought by ASML in 2001. But I assume the old patents all expired by now and ASML has many new ones. But I don't think with anything so complex one can really assign this to a single country anyway.
