“There must never again be and there will never again be a November 1918 in Germany,” was his first political resolution after a great many political ponderings and speculations. It was the first specific objective the young private politician set himself and incidentally the only one he truly accomplished. There was certainly no November 1918 in the Second World War—neither a timely termination of a lost war nor a revolution. Hitler prevented both.
Let us be clear about what this “never again a November 1918” implied. It implied quite a lot. First of all the determination to make impossible any future revolution in a situation analogous to November 1918. Secondly—since otherwise the first point would be left in the air—the determination to bring about once more a similar situation. And this implied, thirdly, the resumption of the war that was lost or believed to be lost. Fourthly, the war had to be resumed on the basis of a domestic constitution in which there were no potentially revolutionary forces. From here it was not far to the fifth point, the abolition of all Left-wing parties, and indeed why not, while one was about it, of all parties. Since, however, one could not abolish the people behind the Left-wing parties, the workers, they would have to be politically won over to nationalism, and this implied, sixth, that one had to offer them socialism, or at least a kind of socialism, in fact National Socialism. Seventh, their former faith, Marxism, had to be uprooted and that meant—eighth—the physical annihilation of the Marxist politicians and intellectuals who, fortunately, included quite a lot of Jews so that—ninth, and Hitler’s oldest wish—one could also, at the same time, exterminate all the Jews.
