All this was inspired by the principle—which is quite true within itself—that in the big lie there is always a certain force of credibility; because the broad masses of a nation are always more easily corrupted in the deeper strata of their emotional nature than consciously or voluntarily; and thus in the primitive simplicity of their minds they more readily fall victims to the big lie than the small lie, since they themselves often tell small lies in little matters but would be ashamed to resort to large-scale falsehoods.
It would never come into their heads to fabricate colossal untruths, and they would not believe that others could have the impudence to distort the truth so infamously. Even though the facts which prove this to be so may be brought clearly to their minds, they will still doubt and waver and will continue to think that there may be some other explanation. For the grossly impudent lie always leaves traces behind it, even after it has been nailed down, a fact which is known to all expert liars in this world and to all who conspire together in the art of lying.
— Adolf Hitler, Mein Kampf, vol. I, ch. X[1]

Last April, perhaps in a surge of Czech nationalism, Ivana Trump told her lawyer Michael Kennedy that from time to time her husband reads a book of Hitler’s collected speeches, My New Order, which he keeps in a cabinet by his bed. Kennedy now guards a copy of My New Order in a closet at his office, as if it were a grenade. Hitler’s speeches, from his earliest days up through the Phony War of 1939, reveal his extraordinary ability as a master propagandist.

“Did your cousin John give you the Hitler speeches?” I asked Trump.

Trump hesitated. “Who told you that?”

“I don’t remember,” I said.

“Actually, it was my friend Marty Davis from Paramount who gave me a copy of Mein Kampf, and he’s a Jew.” (“I did give him a book about Hitler,” Marty Davis said. “But it was My New Order, Hitler’s speeches, not Mein Kampf. I thought he would find it interesting. I am his friend, but I’m not Jewish.”)

Later, Trump returned to this subject. “If I had these speeches, and I am not saying that I do, I would never read them.”
