The Power of Lies :
By means of shrewd lies, unremittingly repeated, it is possible to make people believe that heaven is hell and hell heaven. The greater the lie, the more readily it will be believed. (Adolf Hitler, Mein Kampf)
A lie repeated a thousand times becomes a truth, (Joseph Goebbels, Minister of Propaganda of IIIe Reich,)
"...a truth is not hard to kill and that a lie told well is immortal..."
(Mark Twain, American Jewish writer)
