"No postwar German government believed it could accept such a burden on future generations and survive ...".  Paying reparations is a classic punishment of war but in this instance it was the "extreme immoderation" that caused German resentment. Germany made its last World War I reparation payment on 3 October 2010,  ninety-two years after the end of World War I. Germany also fell behind in their coal payments. They fell behind because of a passive resistance movement against the French.  In response, the French invaded the Ruhr, the region filled with German coal, and occupied it. At this point the majority of Germans were enraged with the French and placed the blame for their humiliation on the Weimar Republic. Adolf Hitler, a leader of the Nazi Party, attempted a coup d'état against the republic to establish a Greater German Reich  known as the Beer Hall Putsch in 1923. Although this failed, Hitler gained recognition as a national hero amongst the German population. The demilitarized Rhineland and additional cutbacks on military infuriated the Germans. Although it is logical that France would want the Rhineland to be a neutral zone, the fact that France had the power to make that desire happen merely added onto the resentment of the Germans against the French. In addition, the Treaty of Versailles dissolved the German general staff and possession of navy ships, aircraft, poison gas , tanks, and heavy artillery was made illegal.  The humiliation of being bossed around by the victor countries, especially France, and being stripped of their prized military made the Germans resent the Weimar Republic and idolize anyone who stood up to it. 
To bring about peace in the world, to stop all wars, there must be a revolution in the individual, in you and me. Economic revolution without this inward revolution is meaningless, for hunger is the result of the maladjustment of economic conditions produced by our psychological states – greed , envy, ill-will and possessiveness. To put an end to sorrow, to hunger, to war, there must be a psychological revolution and few of us are willing to face that. We will discuss peace, plan legislation, create new leagues, the United Nations and so on and on; but we will not win peace because we will not give up our position, our authority, our money, our properties, our stupid lives.
