[these private observations by Adolf Hitler were recorded by the early National-Socialist Hermann Rauschning in 1934 and later published in 1939]
In the future, whole nations will stand against each other, not merely hostile armies.
We are obliged to depopulate as part of our mission of preserving the German population. We shall have to develop a technique of depopulation. If you ask me what I mean by depopulation, I mean the removal of entire racial units. And that is what I intend to carry out—that, roughly, is my task. Nature is cruel, therefore we, too, may be cruel. If I can send the flower of the German nation into the hell of war without the smallest pity for the spilling of precious German blood, then surely I have the right to remove millions of an inferior race that breeds like vermin! And by ‘remove’ I don’t necessarily mean destroy; I shall simply take systematic measures to dam their great natural fertility. For example, I shall keep their men and women separated for years. Do you remember the falling birth-rate of the world war? Why should we not do quite consciously and through a number of years what was at that time merely the inevitable consequence of the long war? There are many ways, systematical and comparatively painless, or at any rate blood-less, of causing undesirable races to die out. We shall undermine the physical health of our enemies as we shall break down their moral resistance.
After all these centuries of whining about the protection of the poor and lowly, it is about time we decided to protect the strong against the inferior. Natural instincts bid all living beings not merely conquer their enemies, but also destroy them. In former days, it was the victor’s prerogative to destroy entire tribes, entire peoples. We should remember, too, that we are merely doing unto others as they would have done to us.
Just as the Jews became the all-embracing world power they are today only in their dispersal, so shall we today become in our dispersal the omnipresent power, the masters of the earth…and bring into operation throughout all Europe and the whole world this process of selection which we have carried out through National Socialism in Germany.
