When explorers first set out to conquer inhospitable places, Antarctica, the poles etc, it was obviously fraught with danger. And the people who got to these places could only stay for a limited duration. Over time, a couple of years at the most, explorers from other countries came and stayed a bit longer, and so on.
Up to present day, people now live and work and study in these conditions for months and months at a time. Mainly because of technology and logistics being as good as they are.
This should be the exact same scenario with the moon.
I can't for the life of me understand how the Russians (who at one point were neck and neck with USA to get there) can be so far behind still with their abilities to get to the moon.
Nor how, as quick as the Chinese or Indians are progressing, that they haven't yet put a man on the moon, seeing as they've been doing it longer than the USA were when they eventually went.
A venture to the moon in this day and age would be a hugely profitable enterprise for whatever country that announced they were going there. The rights for the TV coverage, the merchandise, they would make billions from it over years to come.
The whole world would be watching. It would be one of the biggest events ever to happen ever in the modern age. The end results would far outweigh the initial costs.
But there's not even a snifter of that happening.
In my opinion there are only two reasons why NO ONE has been back in over forty years. Either they found something on the moon originally that could or would be a potential danger to the human race, and warned or showed other countries who intern ceased to try themselves.
Or they simply didn't go in the first place....

...They would make billions in the long run, and I'd strongly disagree with you if you believe otherwise. I mean c'mon, simple disney films rake in millions from merchandise. A manned trip to the moon would rake in astronomical revenues...

That's exactly my point. That's how they would take the money in. People will pay it. Would you honestly not pay £40 to watch it live? I bet you would. I despise pay for view stuff, I pay enough as it is. But I would definitely pay to see it.

They might...might...pay for it once.
And then, just like with Apollo, the novelty of it wears off, and the public stops caring enough to pay again.

Instead of there being six missions, which was overkill, one would suffice.
It would work. Imagine a country announcing a year to the day they will set foot on the moon. It would fire everyone's imagination, especially those who didn't experience it first time around.
Those who did experience it, I can understand their "meh" attitude towards it. For the younger generation it would be "their" experience...

Go to the remains of the Apollo landers to show the amazing feat that happened years ago. Let's see them walking round in HD.

Clearly this is all you have: crossing the VAB is your "they did not have the technology", as this is the only thing you challenge.
Your challenge don't hold up.
Longer term missions are not just briefly mentioned in the introductions, they are specifically the topic of discussion.
Let's look at this one www.stfc.ac.uk...
What is the title?
Mars Radiation Risk Assessment and Shielding Design for Long-Term Exposure to Ionizing Space Radiation
Can we see a few clues there? I don't know about you but the words "Mars" and "Long Term" are pretty major hints that we are not talking about a fast jaunt through the VAB and a week or so in space.
The other article you use ntrs.nasa.gov... is also specifically looking at long term doses for astronauts based on modern standards for exposure. It doesn't just vaguely mention them, it refers to annual dosage rates for long term space workers.
You completely gloss over the fact that both these papers refer to long term exposure levels and just pick out the sentences where they say that aluminium is maybe not the best thing to use in that type of mission given that fancy new materials (and the key word there is "new") are available. Tell us what they should have used then.
You also managed to do some very skilled copying and pasting from an article revealing refinements in our understanding of the VAB. What they discuss are the very dynamic nature of the belts, how they change over a matter of hours as a response to intense solar events. How many of these intense solar events occurred during Apollo missions.
The quote you give about particles penetrating aluminium - which ones do they refer to? Very very very very high energy ones. How many of these are there likely to be? You're also assuming that any craft passing through the VAB would spend a long time in the zone to which the paper refers. The article says they build satellites to survive these problems - are they covered in a foot of lead?
You have, as usual, cherry picked quotes and references that suit your purposes, glossed over the bits that don't suit you and failed to deal with the fundamental issue of proving that Apollo did not cross the VAB, land on the moon and return again, or what the radiation levels would have been during that journey. You ignore the fact that dogs and turtles were given long exposures in space without being instantly fried, and that Gemini XI spent significant periods in the VAB without killing either astronaut, both of whom went on to crew Apollo 12.
Tell us what radiation levels would have been experienced during the Apollo missions. Here's a start:
www.hq.nasa.gov...
Don't forget to chase up the references.
Aluminium was the construction material they used because it matched the design requirements of being both light and provided sufficient protection for the mission duration. It was not the only material involved in the spacecraft's construction. Apollo missions did not spend long enough in the VAB to suffer enough radiation to cause concern. You have failed to provide any evidence that they spent too long in the VAB and you have failed to provide any evidence that the radiation levels they would have experienced, or did experience, were any kind of problem.
If you look at pretty much any study of missions beyond LEO to (for example) Mars or asteroids or wherever the major concern is not what will happen to astronauts crossing the VAB, it is long term exposure to the risks of radiation in deep space. Apollo knew about that risk, had contingencies for it and had monitoring programmes in place to make sure they had enough warning to deal with any solar events that might occur. They put more effort into preventing micro-meteorite damage than they did radiation protection and for good reason - it's more likely to be a real and immediate danger, as opposed to radiation exposure that might cause illness at some point in the future.
Finally, you cannot include a time machine in your claims. You can't produce modern data and modern materials and say "well they should have known this and they should have used these". They didn't have them so couldn't have used them. They built spacecraft and designed missions and procedures based on knowledge they had and made informed judgements about what they considered to be acceptable risks. Changing levels of understanding and changing ideas of what constitutes 'acceptable risk' does not invalidate what went on before.
All you have is this big radiation bogeyman that you think is so important but we're all still waiting for you to produce actual numbers that prove Apollo couldn't have got to the moon without killing its crew. Jarrah tried that and failed miserably.

They don't say anything about short-term missions, or any mention of a time period...none.
The title and introduction refer to longer missions, like to Mars, as 'future' missions. Longer missions are exposed to more of this hazard, compared to shorter missions, as we know.

You contradict yourself within a sentence, the rest of your post is you wriggling on a hook.
Please post evidence that the Apollo shielding provided inadequate protection from the VAB during the astronaut's brief passage through them. You have never done this, no matter how many times you claim to have done so.
Please tell us which technology was not available during Apollo that prevented astronauts landing on the moon.
