Trying to trace things like this is a fools errand though. Trace things back further than that, the microscope was invented in Europe, and further back the magnifying glass somewhere in the Middle East/Mediterranean. You'll just stop wherever it's convenient for the point you're trying to make.
Ultimately, what was available + what was known was put into practice by ASML and they're the ones best at executing that thing right now today, and some things they're the only ones able to too, which isn't very too common.
But I guess only time will tell if they can use whatever they've built and make it into something even more.
It is not. EUV was literally invented in America in government funded research, and licensed to ASML. Taiwan (TSMC) purchased ASML machines.

These have nothing to do with each other. One is a private corporation that made a strategic mistake. The other is a government agency.
Modern, high-yield EULV was not. The CRADA efforts did not produce high-yield dies, nor did it get beyond theorizing modern nodes.

Maybe that's how you wish things were. But we have two admins back-to-back scraping Intel's corpse off the pavement.
If you have a source that says "modern, high-yield EULV" does not use ASML machines, or does not use the laser pulsed tin plasma light source invented in the US, I'd be interested
Claiming that America invented modern high-yield EUV in the lab is like saying Germany invented the Ferrari because Italy imported their steel presses to manufacture it. Not only are you being pedantic, you're not using pedantry to make a distinction that anyone will respect. Chipmaking is not a pushbutton process with line-replaceable units. This kind of reductive reasoning is what puts detail-oriented cultures ahead of profit-oriented ones.
Regardless of what other prior inventions it depended on, EUV technology itself was invented in the US, and we know that factually - it’s not a fool’s errand. ASML literally approached the US government for a chance to license the technology. This was in the late 90s. That’s not to take away the work ASML has done since then to make it commercially viable through their machines (or TSMC in implementing and integrating ASML machines).
