"My motto is: Destroy by all and any means. National-Socialism will reshape the world."
"To me all means will be right. My motto is not: 'Don't, whatever you do, annoy the enemy!' My motto is: 'Destroy him by all and any means.' I am the one who will wage the war!" [Rauschning, The Voice of Destruction, p. 10]
The film distorts the meaning of the sentence that appears here. When the film omits the word "him" from the sentence as it appears in Rauschning, then places a statement about National-Socialist designs on the world after that (without any indication of an ellipse such as "..." to indicate that the two sentences did not originally appear together ) it thereby places in Hitler's mouth a nihilistic declaration of war against the entire world, rather than a theoretical statement about how to conduct some hypothetical war against a hypothetical enemy, which is all that it seems to be in Rauschning.
"With the conception of race, National Socialism will carry its revolution abroad and recast the world." [Rauschning, The Voice of Destruction, p. 143]
Unlike the first clause, this line from Rauschning seems more or less consistent with the notion of National-Socialist worldwide subversion that the film was trying to convey, but remember that Rauschning's conversations with Hitler were already fraudulent before the Hollywood screenwriters got hold of them and started making modifications.
At 15:35 this statement is attributed to Adolf Hitler:
This view attributed to Hitler is quite important, because it rules out negotiated peace with Hitler. It leaves war as the only option. The source for it alleged in the film is "Hitler Interview, October, 1933." But it's not a real interview. It's Rauschning again. It's on page 109 of Rauschning's The Voice of Destruction. This fake quote is still used by some shoddy professional historians, e.g. Martyn Housden at the University of Bradford (UK), and Christian Leitz at the University of Auckland, and David Jablonsky of the U.S. Army War College, are still quoting despite the fact that Rauschning's fraud was exposed in 1983.
This statement attributed to Ernst Hanfstaengl at 24:02 in the second episode of Why We Fight --
"Democracy has no convictions for which men would be willing to stake their lives."
-- also comes from Rauschning. It is a slightly simplified version of what Rauschning represents Hanfstaengl as saying on page 75 of The Voice of Destruction.
"Demoralize the enemy from within by surprise, terror, sabotage, assassination. That is the war of the future."
"When the enemy is demoralized from within, when he stands on the brink of revolution, when social unrest threatens—that is the right moment. A single blow must destroy him. Aerial attacks, stupendous in their mass effect, surprise, terror, sabotage, assassination from within, the murder of leading men, overwhelming attacks on all weak points in the enemy's defense, sudden attacks, all in the same second, without regard for reserves or losses: that is the war of the future."
