This is an honest question, I'm trying my best to word it to not sound like a troll.
ASML was permitted to acquire Cymer in 2013 during the Obama administration under a strict technology sharing and export control agreement with the US government.
The R&D, technology, manufacturing, and all other operations had to remain in the US.
A tiny fraction of the technology itself started as an ineffective "American" invention, copying a Japanese discovery/invention. In fact when ASML acquired the company, specifically because it couldn't do what they wanted and they needed to vastly improve it, a Japanese company had a superior product in the same space, but ASML saw the Japanese company as too much political baggage given how protectionist the Japanese often are.
How funny it all turned out, right?
