You know, "Well, if we can't have it, neither can you?"
Note: France/UK still have nukes and the Netherlands can develop its own if it needs any
New sanctions?, existing sanctions?, tariffs?, that threat is a recurring theme and is losing its power since Trump can just impose sanctions if he wakes up in a bad mood.
What happens if ASML/The Netherlands refuses to comply?
The US imposes sanctions and prevents suppliers from selling to ASML?
That would mean ASML in turn starts refusing to sell to the US and maintain equipment used in the US...
Who's losing the most here?, who caves first?
As for the ban... it's for older DUV machines which China can already build themselves.
EUV machines are still banned.
Hard to protect against espionage and hard to compete with a company that has massive state subsidies.
Easier to just sell them the equipment to prevent this.
Note: they can already produce DUV equipment, just probably not economically viable (yet)
