@luridape7486 No, that's not how it works. Strictly speaking, the inverse square law only applies to point sources of light. The total amount of light you get from an object is proportional to the inverse square of your distance, but only if you can see the same area of the object.
At some point as you approach, say, the Moon, it will fill your entire field of view. After that point, the amount of area you can see will decrease as to the square of your distance. This exactly cancels out the increase in light intensity from a given area with decreasing distance, so the intensity remains the same after that point.
You can test this with your computer screen. Make it all white or some solid color, put your eye maybe two inches away, so it fills your entire field of view. Now reduce the distance to one inch. Did the light double in intensity?

"Technology" can mean devices, such as computers, rockets, the assembly lines to build them, etc, or it can mean knowledge: physics, engineering, blueprints, etc. The technology that NASA lost when Congress defunded then was the devices, not the knowledge.
None of the countries you mentioned has attempted Moon landings recently. Only the Soviet Union ever tried, and they gave up after their N-1 rockets kept blowing up.
