He understood those – politicians and “regular folks” – who did not take his chancellorship seriously. Humanly speaking, they were right, of course – he had a chance of a snowball in hell to stay in power (quite limited, actually) for longer than several months. And acquiring plenary powers in Germany was flatly impossible – there was no question about that.
But it was humanly speaking – i.e. in the opinion of those who did not believe in the supernatural. In Providence. In God. In the Almighty Power. And Adolf Hitler believed in “all of the above” (which for him were one and the same omnipotent spiritual entity).
Hence he knew for a fact that he was, indeed, a fully authorized agent, tool, an instrument of this Almighty Power. The power that will provide him with all supernatural support that he will need to accomplish his Divine Mission – (a) fight and win the existential war with the godless Bolshevik Soviet Union (and with the alien “Jewish race”); and (b) make the Aryan race in general and Germany in particular the masters, the rulers of our world.
Unlike just about every German politician, statesman and government official (and the overwhelming majority of ordinary Germans), Adolf Hitler knew, just knew that the existential all-out open “hot” war with the Soviet Union was inevitable.
For a very simple reason – “Red Tamerlane” Joseph Stalin (a) was totally committed to invading, conquering and transforming Europe (and subsequently the whole world) into a one totalitarian Communist state – a global Union of Soviet Socialist Republics; and (b) by 1933 had the absolute power in the Soviet Union (much more absolute than Hitler would even have in Germany).
As was the war with France and Great Britain. Neither would accept the fusion of immense Soviet resources with the German technologies and management (and thus the emergence of a global German superpower) inevitable after the German victory in the existential war with the Soviet Union.
To win this war, German Army had to launch a pre-emptive strike on the latter. Which required a common border between Germany and the USSR making war between Germany and Poland (and occupation of the latter by the former) inevitable as well.
Which would almost definitely lead to France and Great Britain declaring war on Germany. The war made even more inevitable by the “Alsace-Lorraine problem” as the overwhelming majority of the population of that territory still were of German nationality and thus wanted to be part of Germany, not France.
Germany had neither the resources nor stamina to win the war of attrition (the previous war was lost precisely because it turned into the latter); consequently, the only way to win these wars was by blitzkriegs lasting no more than a few months.
Blitzkrieg against France was crystal-clear – destroy sufficient chunk of French armed forces and occupy sufficient part of French territory to force the French government (not terribly eager to fight even the defensive war in the first place) to essentially surrender.
Soviet Union was simply way too big for its government to be forced to surrender; consequently, the only realistic military objective was to force it (by the abovementioned means) to sign peace treaty on German terms (“Brest-Litovsk II”, if you will).
And after the fall of France and (especially) the defeat of the Soviet Union Britain will have no choice but to accept peace on generous German terms as winning the war without Soviet “cannon fodder” (and a lot of it) was simply impossible. Especially after the German Kriegsmarine (especially its U-boat arm) and incessant Luftwaffe attacks will make everyday life on the island very uncomfortable.
To win these inevitable wars, Germany (more precisely, its Nazi government and Adolf Hitler personally) had to transform its tiny Reichswehr – not capable of protecting the country from an attack by Poland – into the most powerful, fearsome and efficient military force in the world (excluding purely naval operations, of course).
And support it with sufficiently industrial complex (system) – both military (production of military hardware, ammunition and other supplies) and civilian “foundation industries” (oil, coal, metals, energy, chemicals, foodstuffs, etc.).
Obviously, making Germany self-sufficient in foodstuffs and basic raw materials to the maximum extent possible – by developing whole industries for manufacturing substitute “ersatz” products (petrol, synthetic rubber, etc.), increasing the amount of land available for agriculture and maximizing the productivity of existing agricultural land.
And, of course, by acquiring industries and agricultural lands of the whole nations – Czechoslovakia, Austria, Poland and subsequently (for fighting the war with the mighty Soviet Union and no less mighty British Empire) France and other European nations.
