If the Russians thought faking a moon landing was possible, they would have accused the Americans of it. I've read some of the (mostly very stupid) hoax conspiracy theory sites and some of the debunker sites, and I'm 100% sure that the best way to convince people you've been to the moon is to actually go there. There is no doubt at all that the Apollo landings happened, and nothing in the conspiracy theories that doesn't evaporate when exposed to a little high-school science.
