David Irving tells of files he saw/has in a speech relating how MI5 was intimately involved in the 'holocaust' propaganda to the point where he stated something like this:
A Director of MI5, in the wartime propaganda department, talking about the holocaust propaganda said "is was as a wheel, spinning so fast that nobody dared put a hand to it, to stop it, as they would get burned"
I know the holocaust stories & extortion racket really started around the 60s, . Could it be the 'soon to be' extortioners waited until they were sure the British & perhaps the French & USA would not 'confess the truth' as they had for WWI propaganda' (Germans throwing babies into the air and catching them on their bayonets etc.)
This could account for the 'late start' of, and show the 'political power' infesting the racket.
