As for a madman "seizing" power, and leaving aside that he took power by constitutional means, see Walter's post.
In the 1980s (1986, i believe) a German economist showed that the inflation which is usually blamed for Germany's troubles began in 1914, before
the war began. In 1916, the Chief of Staff, Falkenhayn, instituted a war of attrition with his Verdun campaign--he himself referred to his plan as a war of attrition in his memoirs written after the war. He had also wanted to conduct a limited war in the East, but bowed to the pressure of other German officers and committed major resources in the East, as well. Run-away inflation began in 1917, due to the horrible cost of the Verdun campaign, and the hammer blows Haig had rained on the Germans in the Somme campaign. (Haig wanted to continue his attacks in1917, but was overruled by the weasel Lloyd George, who had driven H. H. Asquith from power--but that's not germane to this discussion.) Not only did inflation continue, the rate at which inflation increased began to increase itself, thus leading to the run away inflation.
In fact, one could make a reasonable case that the Paris Peace Conference went rather easy on the Germans. Whether or not, the Germans did not pay their reparations. The bulk of what they did pay was "in kind" in that the Allies seized equipment, machinery and stockpiled resources when the French marched into the Rhineland. What the Germans actually paid, before their debt was forgiven
was worthless because of the astronomical inflation. The hyper-inflated marks they paid were a tiny, tiny fraction of the value which would have been paid if it had been "real" marks. There was absolutely no incentive for the Wiemar government to take steps to end inflation while they were paying reparations. When the reparations were forgiven. inflation was curbed pretty damned quickly.
Essentially, there were two political myths which were promoted relentlessly by right wind politicians in Germany in the post-war period. The first was the "Stab in the back" myth, which held that the German army had never been defeated in the field, but had been betrayed by left-wing politicians. That can be dismissed in one--Ludendorff had set up a new civilian government in the first week of October, 1918, and although he later blamed them for the terms imposed, at the time he admitted to von Hindenburg that they could not avoid negotiations.
The second political myth was the "Versailles Diktat" myth. I've already canvassed that. Compare the case to the terms imposed on France in 1871--five billion gold francs (and gold, of course, is "inflation-proof"). The French not only paid those reparations, they astounded European observers by paying them off in under three years. Part of the Versailles Diktat myth was a claim that this was simply revenge on the part of the French--but that's BS because the Germans didn't pay their reparations (not until after the second world war), and it is indisputable that they did massive damage to French and Belgian infrastructure as they retreated, purely in a spirit of revenge. Although the German reparations had been calculated in gold marks, they were continually reduced, and in 1931, they were cancelled contingent upon the cancellation of Allied war debts to the United States. In 1933, it became irrelevant because Hitler unilaterally cancelled reparations, and at that time, Germany had paid about 13% of its reparations. Of the Central Powers, only Bulgaria paid its full reparations bill.
So basically, Bill, although i'm sure you're too ignorant to understand it, you're just being a stooge for Nazi propaganda.
