They basically (almost) did. In 2013 ASML bought US Cymer(the maker of EUV light sources) and in 2001 ASML acquired the US-based lithography equipment manufacturer Silicon Valley Group (SVG) after it had encountered liquidity issues.
Basically, the US had everything needed, the EUV light sources and lithography machines, just spread over different companies facing financial issues, so ASML came at the right moment and bought them all and integrated into their own business.
Just because ASML is based in NL doesn't mean all of its EUV secret sauce IP is domestically Dutch. Most of it comes from the US, which is why the US government maintains such a high influence of ASML's trade restrictions.
