“It is not Germany that will turn Bolshevist but Bolshevism that will become a sort of National Socialist. Besides, there is more that binds us to Bolshevism than separates us from it. There is, above all, genuine revolutionary feeling, which is alive everywhere in Russia except where are Jewish Marxists. I have always made allowance for this circumstance, and given orders that former Communists are to be admitted to the party at once. The petit bourgeois Social-Democrat and the trade-union boss will never make a National Socialist, but the Communist always will…. Our spirit is so strong, and the power of our magnificent movement to transform souls so elemental, that men are remodeled against their will… A social revolution would lend me new, unsuspected powers. I do not fear permeation with revolutionary Communist propaganda.”

Context: The Germany of today is a National Socialist State. The ideology that dominates us is in diametrical contradiction to that of Soviet Russia. National Socialism is a doctrine that has reference exclusively to the German people. Bolshevism lays stress on international mission. We National Socialists believe a man can, in the long run, be happy only among his own people. We are convinced the happiness and achievements of Europe are indissolubly tied up with the continuation of the system of independent and free national States. Bolshevism preaches the establishment of a world empire and recognizes only section of a central international. We National Socialists grant each people the right to its own inner life according to its needs and its own nature. Bolshevism, on the other hand, establishes doctrinal theories that are to be accepted by all peoples, regardless of their particular essence, their special nature, traditions, etc. National Socialism speaks up for the solution of social problems, issues and tensions in their own nation, with methods that are consistent with our common human, spiritual, cultural and economic beliefs, traditions and conditions. Bolshevism preaches the international class struggle, the international world revolution with the weapons of the terror and the violence. National Socialism fights for the reconciliation and consequent adjustment of the differences in life and the union of all for common benefits. Bolshevism teaches the overcoming of an alleged class rule by the dictatorship of the power of a different class. National Socialism does not attach importance to a only theoretical rule of the working class, but especially on the practical improvement of their living conditions and standard of living. Bolshevism fights for a theory and, for it, sacrifices millions of people, immense values of traditional culture and traditions, and achieves, compared with us, only a very low standard of living for all. As National Socialists, our hearts are full with admiration and respect for the great achievements of the past, not only in our own people but also far beyond. We are happy to belong to an European cultural community that has so tremendously embossed today's world with a stamp of its mind. Bolshevism rejects this cultural achievement of mankind, claiming that has found the beginning of the real cultural and human history in the year of birth of Marxism. We, National Socialists, do not want to be of the same opinion as our church organizations in this or that organizational question. But we never want a lack of belief in religion or any faith, and do not wish that our churches become club-houses or cinemas. Bolshevism teaches the godlessness and acts accordingly. We National Socialists see in private property a higher level of human economic development that according to the differences in performance controls the management of what has been accomplished enabling and guaranteeing the advantage of a higher standard of living for everyone. Bolshevism destroys not only private property but also private initiative and the readiness to shoulder responsibility. It has not been able to save millions of human beings from starvation in Russia, the greatest Agrarian State in the world. It would be unthinkable to transfer such a catastrophe into Germany, because, at the of the day, in Russia there are 10 city dwellers for every 90 country dwellers, but in Germany for only 25 farmers there are 75 city dwellers. National Socialists and Bolshevists both are convinced they are a world apart from each other and their differences can never be bridged. Apart from that, there were thousands of our people slain and maimed in the fight against Bolshevism. If Russia likes Bolshevism it is not our affair, but if Bolshevism casts its nets over to Germany, then we will fight it tooth and nail.
