Even in war time and under the influence of propaganda , 19 July 1941 Hitler stated:
“Stalin is one of the most extraordinary figures in world history. He began as a small clerk, and he has never stopped being a clerk. Stalin owes nothing to rhetoric. He governs from his office, thanks to a bureaucracy that obeys his every nod and gesture.
This is a criticism, not a compliment!
https://www.quora.com/What-did-Hitler-and-Stalin-think-of-each-otherHitler once summed up Stalin brilliantly: “Stalin started out as a desk clerk and he is still a desk clerk.” What he meant, of course, is that Stalin thought and acted like a mediocre bureaucrat, not a statesman and visionary like himself.
More Hitler quotes that shows Hitler's dislike for Stalin (rooted in anti-Turanism, not merely anti-communism):
"When Russia barricades herself within her frontiers, it's to prevent people from leaving the country and making certain comparisons. That's why Stalin was obliged to introduce Bolshevism into the Baltic countries, so that his army of occupation should be deprived of all means of comparison with another system."
"A people can prove to be well fitted for battle even although it is ill fitted for civilisation. From the point of view of their value as combatants, the armies of Genghiz Khan were not inferior to those of Stalin (provided we take away from Bolshevism what it owes to the material civilisation of the West)."
"Stalin pretends to have been the herald of the Bolshevik revolution. In actual fact, he identifies himself with the Russia of the Tsars, and he has merely resurrected the tradition of Pan-Slavism. For him Bolshevism is only a means, a disguise designed to trick the Germanic and Latin peoples. If we hadn't seized power in 1933, the wave of the Huns would have broken over our heads."
"Stalin is half beast, half giant. To the social side of life he is utterly indifferent. The people can rot, for all he cares."
"Stalin is an anarchist educated in an ecclesiastical college! Our newspapers ought to ask whether he and Churchill sang psalms together in Moscow!"It is only correct to say that Hitler dared not underestimate Stalin:
"Stalin, too, must command our unconditional respect. In his own way he is a hell of a fellow ! He knows his models, Genghiz Khan and the others, very well, and the scope of his industrial planning is exceeded only by our own Four Year Plan."When Hitler uses the term 'respect', it is in the sense of viewing Stalin as a serious threat not to be taken lightly, not in the sense of viewing him as a rolemodel.
