Quickly looked at those two wiki links, seems to support my point of view. Feel free to point me to the examples in there that aren't refuted in the very same article.
You're right to be sceptical of wiki links of course, however you don't seem to take what sources they use and list into account.
This link is from the document I linked to.

This is from the Japanese Aerospace Exploration Agency. This explains how they during their SELENE mission made 3D images of the surface of the moon, then showing how the images from the Apollo landing site looks pretty much exactly like in the photos in their 3D model.
This is of course absolute evidence that the moon landings happened. Unless you want to state that this is just part of the conspiracy, this then would again adds even more people to the list of conspirators.
Seeing as this is from 2008 that would not only invalidate your claim that that this was done because of the cold war and of course mean that your estimate of "20 people" would have to be added to, to say the least.
That was looking at the sources of just one of the points in that wiki article...
