I dont think the majority of germans supported war, I dont think the majority of Germans were pro Nazi either, in the sense that the Nazis wanted war. Most germans in the early 30's wanted relief from the economic hardships of the depression , they also wanted some justice (as they saw it) from the humiliation of Versaille.
In the beginning Hitler worked to those aspirations. Using an essentially keynesian economic model, Hitler got germany working again......and then gradually many of those workers were tranferred to armament production, a subtle but dangerous shift .
Hitler at the same time worked to right the perceived "injustices" brought about by Versailles. Whether Versailles was in fact an injustice or not is an altogether different debate. i happen to think it was not. Germany at the end of WWI should have been forced to the negotiating Table unconditionally, as Pershing had advocated. But they werent. The treaty was supposed to follow Wilsons "14 points" but ended up being a nasty petty but inneffective treaty. Because it was a relatively benign negotiated settlement, but with typically French nastiness about it, it fostered the myth in post war germany that she had been "stabbed in the back","betrayed", and "undefeated".
Whatever the truth about Versailles, the perception across Europe in the 1930s was that it had injustices about it, so as Hitler worked to eliminate those "injustices", many European neighbours, anxious for peace, allowed the Germans to tear up the treaty restrictions. Fair enough. I dont agree with the thinking but i can understand it. But Hitler never had the slightest intention of just getting rid of Versailles. as is clearly set out in his manifesto, he intended to embark on an aggressive war of conquest and enslavement in Europe, with the objective of establishing "colonies" and "living space" in Eastern Europe. It was consciously decided in those formative years that the current occupants were not human, "untermenschen" that were like vermin to be ruthlessly exterminated. How anyone can work or believe that position to be reasonable or justafiable at any level is beyond me. It was that thinking, and the actions that served to achieve that outcome, that led to the outbreak of WWII in the traditional sense, and the immense suffering of the Polish people. We should never forget that.
