You obviously fall into the trap of believing that hard science cares about politics, and that money thrown at problems as part of national strategic planning magically solves them. But for anyone else legitimately interested in understanding the topic better and having a glimpse at its complexity, those are great resources:

If the above is too advanced, this can serve as a good primer and answers "how the heck did we get there": https://www.youtube.com/watch?v=Pt9NEnWmyMo

Also, I never wrote that China will never get to EUV (or eventually something beyond that), just that it will take a very long time, because the complexity is spread across several very distinct scientific disciplines, integrating them is a challenge of its own (again, watch the videos), and packaging this into a system that meets the scale and reliability requirements to make it commercially viable hasn't been reproduced to date.

EUV is complex, unlike nuclear weapons and energy, 5G, space stations, probes to the dark side of the moon and hypersonic missiles. Those things are simple.

EUV is complex. And more so than the accomplishments you mentioned: nuclear weapons were cracked in the 1940's, probe moon landings in the 50's and space stations in the 70's. All have since been reproduced by several nations in isolation. That is not the case of state of the art lithography. No single nation "owns" it because it truly is a multinational endeavor.

(And actual hypersonic missiles haven't made it to the battlefield, and 5G is about commoditization and standardization, by the ITU, an organ of the united nations, so I'm not sure exactly how that adds to your rhetoric)
