I wasn’t saying China has no right to have a rover on the moon. But the mere act of doing so is what causes technology to boom. That technology blooms into all kinds of uses for good and bad. Us keeping spurs our innovation to keep pace. Those uses can not be imagined or foretold. I used present day computing as an example.
Take Sputnik, we were in a Cold War with the USSR. If they could put a satellite into it orbit what else could they do? Could they put a Nuclear warhead up there. Even had they not been able to, had we sat by then there is no “Star Wars” that Reagan used to pretty much spend the USSR into submission ending the Cold War.
China has already has a stated goal of becoming THE ONE superpower on Earth. The technology they derive from their activities of going to and exploring the moon may very well make that goal much more likely. Us keeping up will enhance our space capabilities which will be important in ensuring the protection of all the satellites that keep our current way of life possible. If we can’t protect our satellites enabling communication, enabling our television broadcast, and our military capabilities then we are royalty screwed. We all have GPS on our phones as a byproduct of the US military having satellites in space. Plus the simple fact that we are keeping up is a deterrent to them using the technology they glean from going to the moon for nefarious actions that may disable those very satellites. As I said, disabling a nation without ever firing a shot.
What if the big step forward that happened at Kitty Hawk happened in Berlin instead and we decided not to keep up, 20 years later a Hitler comes along and has that technology at his disposal and dominates the world. You have to look way beyond the fact that they have a rover up there. And it’s not being scared. We didn’t develop the hydrogen bomb because we were scared. We did because it was the next step up as the USSR had matched our weapon capabilities. If you can’t wrap your head around that then I hate it for you.
