Well how good is google earth? Can’t you make out something say the size of a car easily?
You have to know the military spysat’s are much greater, so there is a quick answer for you as to how well they can see things. To my point whatever they have if armed with a powerful laser could probably strike a target from up in space.
Google Earth is limited by the laws of physics, too. And the highest-resolution imagery they have is from aircraft or even cars, not from satellites. And, in fact, a lot of their database does in fact come from spy satellites.
There are no minerals on the moon that are so rare on earth that it would be economical to get them from the moon. As for helium3, first solve the problem of hot fusion, and explain why you prefer going all the way to the moon for helium3 rather than the much easier Deuterium tritium reaction, then we can talk.
I think the president guy wants a Space Force so that he can take diplomacy up there, throw it out the window and watch it burn up in the atmosphere. Much easier to immolate it than to try to figure out how to make it work.
“How powerful are cameras on modern spy satellites? No-one knows, but here is a misleading photoshopped artist’s conception, and they must be far more powerful than commercial satellites, because reasons!”
And when he fails to do that, he’ll then take it back inside, and try to burn it with a lighter, and claim that that’s the same thing. And then he’ll fail at that, too, because he’s just opened a window and let all the oxygen out.
