Don't forget that people make up this kind of thing too. People on forums. The KKK made up all kinds of distorted quotes from Jewish holy books that are still used in conspiracy circles. You'll probably find that it stems from a misquote taken out of context, or is made up. As there is no official record of it ever coming from his mouth it is logical to assume it never did, until evidence DOES crop up, that is.
If you can prove it you have to accept it.
I don't doubt that the lower ranks of the military and government make up all kinds of stuff to stir up conspiracy folk too. I saw footage supposedly of a mice being knocked out by a psychic funded by the US government. It looked suspiciously like what happens when you cut off oxygen and then return it.
They also provided footage to show a goat under the same influence and it looked very much like the narcoleptic goats that came to the fore around that time.
This was all from this guy...
