A lot of the IP in what ASML does is held by KLA, Intel, IBM, etc. So america has quite a lot of say in it.
Yes, but their say will only work as long as both parties feel that the other party honors their contractual obligations.
Hearing the inaugural speech of President Trump, I feel that some treaties and contracts might soon be worth less than the paper they were written on, if breaking those somehow gives national benefits in the quest to "make America great again".
That is how Mr. Trump's speech came across to me anyway. Perhaps and hopefully that is untrue, I'm not a native speaker, so perhaps I lost some subtle nuances.
